Definitions
- the present invention relates to a deposit group of the type specified in the preamble of the first claim.
- the subject matter of the invention introduces an innovative device for depositing a liquid (such as a glue or a dye, a perfume/essence) on a suitably continuous sheet.
- a liquid such as a glue or a dye, a perfume/essence
- the sheets can be made either of a paper material (corrugated, preferably smooth), a polymeric material, or a cellulose hydrate such as cellophane.
- the deposit group also known as gluer
- gluer is suitable to place a gluing liquid on a sheet, allowing its gluing to an additional sheet, thus providing a processed sheet.
- it is used to deposit a dyeing liquid on a continuous sheet so as to colour it entirely or preferably to reproduce thereon an image or a writing.
- the deposit group consists of a tank, also called chamber, containing the liquid to be deposited on the sheet; a roller for withdrawing the liquid from the tank; a laying roller interposed between the drawing roller and the paper/polymer sheet, which is suitable to withdraw the liquid from the drawing roller and to place it on the sheet; a contrast cylinder on which the laying roller rests, coming into contact with the sheet and ensuring the laying down of the liquid on the sheet; and a crankcase supporting the laying roller, the drawing roller and the contrast cylinder.
- the tank and the drawing and laying rollers are mounted on a support structure hinged to the crankcase, and the deposit group comprises a pneumatic cylinder for controlling the rotation of the tank and the rollers with respect to the contrast cylinder between a working position, in which the laying roller is close to the contrast cylinder, and a machine stop position, in which the tank and the rollers are moved away from the cylinder at a predetermined distance from the contrast cylinder.
- This distance is important in the case of gluing for preventing, during machine stoppage, the sheet, when in contact with the laying roller, from sticking to the same laying roller and/or to the contrast cylinder.
- Such distance is equal to 25-50 mm so that, irrespective of the thickness of the sheet, said contact between the sheet and the laying roller is prevented.
- a first drawback is the complex execution of the maintenance or repair operations on the deposit groups known to date.
- the above-mentioned overturning of the tank, the drawing roller and the laying roller defines a free area of limited size, which ensures a limited freedom of movement to the operator.
- the technical task underlying the present invention is to devise a deposit group, which is capable of substantially obviating the above-mentioned drawbacks.
- a major object of the invention is to provide a deposit group, which allows maintenance and repair operations to be performed in a simple and quick way.
- Another important object of the invention is to obtain a deposit group, which avoids the presence of long sections of sheet devoid of gluing, dyeing or other liquid to be deposited.
- the measures, values, shapes and geometric references when associated with words like “about” or other similar terms such as “almost” or “substantially”, are to be understood as unless measurement errors or inaccuracies due to production and/or manufacturing defects and, especially, unless a slight difference from the value, the measure, the shape, or the geometric reference with which it is associated.
- these terms if associated with a value, preferably indicate a difference of not more than 10% of the value itself.
- the deposit group according to the invention is indicated by the numeral 1 .
- a fluid preferably a liquid (e.g. a glue or a colour)
- a raw, preferably continuous sheet 1a e.g. a glue or a colour
- raw sheet simply identifies the sheet before the liquid is deposited thereon by the deposit group 1.
- the raw sheet differs from the processed sheet 1b, which in fact comprises the raw sheet 1 a and the liquid deposited thereon.
- the deposit group 1 can deposit a (fluid, in detail liquid) glue on the raw sheet 1a, allowing its gluing to at least an additional, preferably continuous sheet 1c . It is therefore capable of gluing together two or more sheets 1a and 1c, forming a processed sheet 1 b comprising said at least two sheets 1 a and 1 c, hence with two or more layers.
- a (fluid, in detail liquid) glue on the raw sheet 1a, allowing its gluing to at least an additional, preferably continuous sheet 1c . It is therefore capable of gluing together two or more sheets 1a and 1c, forming a processed sheet 1 b comprising said at least two sheets 1 a and 1 c, hence with two or more layers.
- one or more of the sheets 1 a, 1b and 1 c can also have two or more layers.
- the deposit group 1 can be used to deposit a (fluid, in detail liquid) dye on the raw sheet 1 a so as to form a single processed sheet 1 b exhibiting a writing and/or a coloured image.
- a (fluid, in detail liquid) dye on the raw sheet 1 a so as to form a single processed sheet 1 b exhibiting a writing and/or a coloured image.
- the sheets 1 a, 1b and 1 c can be made either of a paper material (corrugated, or preferably smooth), a polymeric material, or a cellulose hydrate such as cellophane. In detail, they are made of paper and the liquid is a glue.
- the group 1 may be part of a processing line of continuous sheets.
- This line can comprise multiple deposit groups 1, so as to deposit several liquids and, for example, obtain a processed sheet 1b with more than two layers or exhibiting a multi-coloured reproduction.
- the deposit group 1 is suitable to define a sliding path (highlighted with arrows in Fig. 2b ) of at least one sheet and therefore may comprise one or more cylinders (described below) suitable for defining the sliding path, and preferably at least partly motorised, so as to control the movement of the at least one sheet along said sliding path.
- the deposit group 1 may comprise a contrast cylinder 2 along which at least one raw sheet 1a slides; at least one laying block 3 for depositing at least one liquid on the raw sheet 1a; and, suitably, a control unit suitable to control the operation of the group 1 based on a command given by the operator.
- the contrast cylinder 2 defines a preferably substantially horizontal rotation axis 2a.
- the contrast cylinder 2 can be motorised.

- the slide cylinder 4 can be motorised.
- the slide cylinder 4 may comprise an additional reproduction formed on the outer surface for the sliding of the additional sheet 1c, which is suitable to be reproduced on the additional sheet 1c.
- This additional reproduction can be somewhat similar to that of the contrast cylinder 2.
- the outer surface of the slide cylinder 4 is smooth.
- the deposit group 1 may comprise a support structure 5 for the contrast cylinder 2, the at least one laying block 3 and the slide cylinder 4, if present. It should be noted that the various cylinders are associated with the structure 5 in a resolvable manner so as to allow its replacement.
- Said support structure 5 comprises two side panels 51 suitable to enclose and support the contrast cylinder 2, the at least one laying block 3 and the slide cylinder 4, if present.
- the side panels 51 are substantially perpendicular to the rotation axis 2a, and suitably vertical.
- the side panels 51 can be anchored to the ground, and in particular they define the only points of anchorage/support of the deposit group 1 to the ground. Consequently, the laying block 3 is spaced from the ground.
- the deposit group 1 may comprise at least one laying block 3 (preferably only one) for depositing at least one liquid, suitably a glue or dye, on at least part of the raw sheet 1a when it slides on the contrast cylinder 2.
- the laying block 3 comprises, for each liquid to be deposited, a dispenser 31 suitable to dispense the liquid; and at least one roller suitable to withdraw the liquid from the dispenser 31 and to deposit it on the raw sheet 1a; and suitably a feeding apparatus suitable to withdraw the liquid from a tank and bring it to the dispenser 31.
- the laying block 3 may comprise a dispenser 31; a drawing roller 32 for withdrawing the liquid from the dispenser 31; and a laying roller 33 interposed between the drawing roller 32 and the contrast cylinder 2, which is suitable to receive the liquid from the drawing roller 32 and place it on the raw sheet 1a when it slides on the contrast cylinder 2.
- the dispenser 31 may comprise a chamber containing the liquid, and preferably at least partially filled by the feeding apparatus; and one or more blades suitable to ensure the correct dosage and distribution of the liquid on the at least one roller.
- Each roller 32 and 33 defines an additional rotation axis substantially parallel to the rotation axis 2a.
- the drawing 32 and the laying 33 rollers are, at least when the group 1 is in operation, in mutual contact so as to allow the passage of liquid between said rollers 32 and 33.
- the drawing cylinder 32 can be screened and preferably identifiable as an anilox cylinder.
- the laying roller 33 can have on its outer surface a reproduction suitable to be reproduced on the raw sheet 1a. This reproduction is identifiable as a bas/high relief reproducing, for example, dots and/or figures.
- the outer surface of the laying roller 33 can have radial protrusions (identifiable as rings equally spaced along axis 2a, figures or writings) substantially constituting the only deposit points of the liquid on the raw sheet 1a.
- the outer surface of the laying roller 33 is smooth.
- the laying block 3 may comprise a support frame 34 for the dispenser 31 and the at least one roller 32 and 33, which can allow said dispenser 31 and the at least one roller 32 and 33 to be moved simultaneously, as described hereinafter.
- the support frame 34 comprises two walls 341 suitable to enclose and support the dispenser 31 and the at least one roller 32 and 33.
- the walls 341 are substantially perpendicular to the additional axis of the at least one roller 32 and 33 and hence to the rotation axis 2a. Preferably, the walls 341 are vertical.
- the walls 341 are substantially parallel to the side panels 51.
- the distance between the walls 341 is substantially different from the distance between the panels 51 so that they can slide reciprocally, and in particular so as to superimpose the walls 341 onto the side panels 51 with respect to the rotation axis 2a. Conveniently, the distance between the walls 341 is substantially greater than the distance between the panels 51.
- Said distances are calculated along the rotation axis 2a.
- the laying block 3 may comprise a distance-adjusting member.
- the adjusting member is suitable to vary the distance between the rollers 32 and 33, thus moving the assembly of the drawing roller 32 and dispenser 31 with respect to the laying roller 33 preferably along a direction perpendicular to the rotation axis 2a, and more preferably to the gravitational gradient.
- the adjusting member is suitable to move the dispenser 31 with respect to the drawing roller 32 by varying the distance between the dispenser 31 and the drawing roller 32, preferably along a direction perpendicular to the rotation axis 2a, and more preferably to the gravitational gradient.
- the adjusting member is adapted to move both said assembly with respect to the laying roller 33 and the dispenser 31 with respect to the drawing roller 32.
- the deposit group 1 may comprise at least one pressure member 6 for pressing the sheets 1 a and/or 1 c on the cylinders 2 and/or 4.
- the deposit group 1 can comprise a pressure member 6 arranged, with respect to the raw sheet 1 a, upstream of the laying block 3 and adapted to press the raw sheet 1 a against the contrast cylinder 2.
- the deposit group 1 can comprise a pressure member 6 arranged, with respect to the additional sheet 1c, upstream of the slide cylinder 4 and adapted to press the additional sheet 1c against the said cylinder 4.
- the deposit group 1 can comprise a pressure member 6 arranged downstream of the laying block 3 and adapted to press any additional sheet 1c against the contrast cylinder 2 and hence the raw sheet 1 a, ensuring the gluing of the sheets 1a and 1c.
- the deposit group 1 comprises two of said pressure members 6, and in detail all of the above described three pressure members 6.
- Each pressure member 6 comprises a pressure cylinder 61 adapted to press said sheet 1a and/or 1c against said cylinder 2 and/or 4; and a kinematic mechanism for moving the pressure cylinder 61 adapted to move the pressure cylinder 61 with respect to the cylinder 2 and/or 4 and thus to adjust the pressure exerted by the pressure cylinder 61 on the cylinder 2 and/or 4.
- the rotation axis of the pressure cylinder 61 of each pressure member 6 is parallel to and advantageously coplanar with the rotation axis of the cylinder 2 and/or 4.
- the plane on which the rotation axes of the pressure cylinder 61 and of the cylinder 2 and/or 4 lie, against which the pressure cylinder 61 presses the sheet 1a, 1b and/or 1c, is transverse to the gravitational gradient as can be easily understood, for example, from Fig. 2b .
- the pressure kinematic mechanism may comprise a thrust piston 62 that moves the pressure cylinder 61 with respect to the cylinder 2 and/or 4; and an L-shaped lever 63 of the first kind, the ends of which are hinged to the pressure cylinder 61 and the thrust piston 62, which is pivoted to the support structure 5.
- the deposit group 1 may comprise a mover 7 adapted to move reciprocally the laying block 3 and the contrast cylinder 2, defining for the deposit group 1a working configuration ( Fig. 2b ), in which the working distance between the cylinder 2 and the block 3 is substantially not greater than the thickness of the raw sheet 1a; and a maintenance configuration ( Fig. 2a ) in which the maintenance distance between the contrast cylinder 2 and the laying block 3 is greater than the working distance.
- the working distance is not greater than 0.1 mm.
- the maintenance distance is substantially equal to at least 0.5 m, preferably substantially comprised between 0.5 m and 1 m, and more preferably substantially equal to 0.7 m.
- the working and maintenance distances are calculated between the contrast cylinder 2 and the laying roller 33 perpendicularly to the rotation axis 2a.
- the mover 7 is engaged with the support structure 5 and support frame 34, more in particular with the walls 341 and the side panels 51, mutually constraining the block 3 and the structure 5.
- the mover 7 comprises at least one actuator 71 adapted to reciprocally move the block 3 and the cylinder 2.
- the actuator 71 may be linear and its ends may be constrained to the walls 341 and the panels 51, so that it operates said reciprocal motion by varying its elongation.
- the actuator, and therefore the mover 7, are suitable to define stable positions between the laying block 3 and the contrast cylinder 2 almost exclusively at its end and start of travel, i.e. at its maximum and ⁇ or minimum extension.
- the mover 7 and, precisely, the actuator 71 define a stable maintenance configuration in which they exert a force to maintain the maintenance configuration.
- the actuator 71 can be pneumatic, electronic or hydraulic.
- the mover 7 comprises two actuators 71, each subtended between a wall 341 and the adjacent side panel 51.
- the mover 7 may comprise at least one abutment against which the deposit block 3 abuts when the group 1 passes into the working configuration.
- Said abutment is adjustable by varying the distance between the deposit roller 33 and the contrast cylinder 2 on the basis of the thickness of the sheet.
- the mover 7 may comprise at least one guide 72 integral with the support structure 5, and more precisely with the side panels 51; and for each guide 72, at least one slider 73 integral with the laying block 3, and in particular with the walls 341, and suitable to slide along the guide 72.
- the mover 7 comprises two guides 72 for each side panel 51; and two sliders 73 for each guide 72.
- the guide 72 defines a sliding axis for the slider 73 substantially parallel to the movement axis 7a.
- the deposit group 1 may comprise at least one limiter 8 suitable to limit the stroke of the mover 7 by reducing the possible mutual spacing between the contrast cylinder 2 and the laying block 3 and preventing the maintenance configuration from being reached.
- the limiter 8 enables the group 1 to vary its own configuration between the working configuration and a stationary machine configuration interposed between the working and maintenance configurations, thereby defining a machine stop distance (between the contrast cylinder 2 and the laying block 3) intermediate between the working and maintenance distances.
- the limiter 8 defines an active position in which it limits the stroke of the mover 7 and the group 1 varies its configuration, suitably exclusively between the working and the stationary machine configurations; and a passive position in which the limiter 8 does not limit the stroke of the mover 7 and the group 1 varies its configuration, suitably exclusively between the working and the maintenance configurations.
- machine stop distance is calculated between the contrast cylinder 2 and the laying roller 33 perpendicularly to the rotation axis 2a.
- the limiter 8 is adapted to define a machine stop distance ranging between a maximum value and a minimum value.
- the limiter 8 by preventing at least a further distancing between the laying block 3 and the contrast cylinder 2, allows the mover 7 to define a stable stationary machine configuration wherein, in fact, the limiter 8, by preventing a further distancing between the block 3 and the cylinder 2, causes the mover 7 to exploit the blockage provided by the limiter 8 in order to exert a force to maintain the stationary machine configuration opposing a variation in the distance between the laying block 3 and the contrast cylinder 2.
- the limiter 8 can be mechanical and, for example, limit the stroke of the mover 7 by engaging the contrast cylinder 2 with the laying block 3, and precisely the support structure 5 with the support frame 34.
- the deposit group 1 comprises two limiters 8, each of which suitable to engage a side panel 51 with the adjacent wall 341.
- a limiter 8 may comprise a slot 81 and a stop 83 , one of which is integral with the support structure 5 and the other with the support frame 34.
- the slot 81 is integral with the support structure 5, and in particular with a side panel 51.
- the stop 83 is suitable to be integral with the support frame 34, and precisely with a wall 341.
- the slot 81 has an axis extending substantially parallel to the movement axis 7a.
- the slot 81 may have a length, as calculated along the axis 7a, at least equal to the maximum value of the machine stop distance so that the stop 83 is able to slide therein along the movement axis 7a over a length substantially equal to the maximum value of the machine stop distance.
- It may be formed in the side panel 51 or in a plate integral with it.
- the limiter 8 may comprise an additional slot 82 integral with the support frame 34, and more precisely with a wall 341.
- the additional slot 82 has an axis extending substantially parallel to that of the slot 81.
- the additional slot 82 may have a length, as calculated along the axis 7a, at least equal to the difference between the maximum and minimum values of the machine stop distance so that the stop 83 can slide therein along the movement axis 7a over a length substantially equal to said distance.
- the stop 83 is connected to the control unit so as to be controlled by the same and thus it places the limiter 8 in the passive or active position based on a command coming from the control unit as described below.
- the stop 83 comprises a pin 831 suitable to fit into the slots 81 and 82 and a shifter 832 suitable to move the pin 831 with respect to the slots 81 and 82, defining said active position ( Fig. 3a ) and passive position ( Fig. 3b ).
- the pin 831 In the active position, the pin 831 is inserted in both of the slots 81 and 82. In the passive position, it is not inserted in at least one of the slots 81 and 82 (suitably it is inserted only in the additional slot 82).
- the shifter 832 is suitable to move the pin 831 along a translation axis 83a substantially perpendicular to the movement axis 7a, and in particular substantially parallel to the rotation axis 2a.
- the stop 83 may comprise an anchor plate 833 for anchorage to the wall 341 through constraining means, which are releasable, or in detail resolvable and define a passage hole for the pin 831.
- the anchor plate 833 can thus have screws or bolts.
- Said passage hole is substantially shaped against the pin 831, and in particular the shifter 832.
- the limiter 8 may comprise a regulator 84 adapted to enable adjustment, suitably in a continuous manner, of the machine stop distance between a minimum value, greater than the working distance, and a maximum value, smaller than the maintenance distance.
- the maximum value is substantially less than 10% of the maintenance distance. It is substantially less than 5 cm, and in detail less than 3 cm. More in detail, it is substantially equal to 2.5 cm.
- the minimum value of the machine stop distance is at least less than 15 times the working distance. It is substantially less than 1 cm, and in detail less than 0.5 cm, and more in detail less than 0.2 cm, and conveniently equal to 0.1 mm.
- the machine stop distance has a minimum value at least equal to 0.1 mm and a maximum value of less than 5 cm.
- the regulator 84 is suitable to vary the position of anchorage of the stop 83 to the laying block 3, and in particular to move the stop 83 along the movement axis 7a by adjusting the position of the stop 83 with respect to the slots 81 and 82, and in particular to the additional slot 82.
- the regulator 84 may comprise, at each of the resolvable constraining means of the anchor plate 833, an adjustment slot extending substantially parallel to the movement axis 7a, i.e. to the slots 81 and 82.
- Said adjustment slots are suitable to adjust the machine stop distance on the basis of the position of the passage hole and therefore of the pin 831 with respect to the additional slot 82, by modifying the stroke of the pin 831 in the slot 81.
- the operator constrains the stop 83 so that the pin 831 is at the end of the additional slot 82 distal to the cylinder 2, and so as to have the minimum value of the machine stop distance.
- the operator places the pin 831 at the end of the additional slot 82 proximal to the contrast cylinder 2.
- the operator places the stop 83, and in particular the pin 831, in an intermediate position between those described above.

- the monitoring station 9 sends a sliding error signal if it detects the absence of at least one sheet for example due to a breakage thereof.
- Another possible sliding error precisely in the case of a multilayer sheet 1 a, 1b and/or 1 c, is the breakage of only some of the layers which, by not sliding any more along the sliding path, accumulate causing spacing between two components of the group 1 (in detail between the contrast cylinder 2 and the deposit roller 33 and/or between the walls 341 and the side panels 51) detected by the station 9. It is pointed out that the monitoring station 9 can detect distance variations of the order of tenths of mm.
- the monitoring station 9 monitors the passage of the sheet at a point/area of the sliding path, detecting an error in the sliding of at least one of the sheets 1 a, 1b and/or 1 c and/or an undesired variation of the distance between the components of the group 1. It may comprise one or more of an optical/magnetic sensor and a camera.

- the control unit commands the transition to the stop configuration, and in particular it orders the mover 7 to stop the maintenance force and the stop 83 to pass into the passive position.
- the invention provides significant advantages.
- a first advantage is the presence of the monitoring station 9 which, by detecting an incorrect paper flow, blocks the group, thereby preventing breakdowns thanks to the cessation of the maintenance force that moves the block 3 away from the contrast cylinder 2, avoiding accumulations.
- This aspect brings the deposit block 3 close to the contrast cylinder 2 in complete safety, minimizing the machine stop distance, by adjusting it to the thickness of the sheet being processed, and therefore the transition time from the stationary machine configuration to the working configuration.
- Another advantage is that the deposit group 1 reduces the ratio of liquid-free sheets, thus avoiding waste from production by distributors.
- a non-secondary advantage is that, in the maintenance configuration, the laying block 3, compared to the known groups, has an increased distance from the contrast cylinder 2, thus ensuring a large operating/intervention space.
- Another advantage is that the deposit group 1, being fully anchored to the support structure 5, is transportable already assembled.

Abstract
Description
- The present invention relates to a deposit group of the type specified in the preamble of the first claim.
- In particular, the subject matter of the invention introduces an innovative device for depositing a liquid (such as a glue or a dye, a perfume/essence) on a suitably continuous sheet.
- The sheets can be made either of a paper material (corrugated, preferably smooth), a polymeric material, or a cellulose hydrate such as cellophane.
- As is well known, the deposit group, also known as gluer, is suitable to place a gluing liquid on a sheet, allowing its gluing to an additional sheet, thus providing a processed sheet. Alternatively, it is used to deposit a dyeing liquid on a continuous sheet so as to colour it entirely or preferably to reproduce thereon an image or a writing.
- To date, the deposit group consists of a tank, also called chamber, containing the liquid to be deposited on the sheet; a roller for withdrawing the liquid from the tank; a laying roller interposed between the drawing roller and the paper/polymer sheet, which is suitable to withdraw the liquid from the drawing roller and to place it on the sheet; a contrast cylinder on which the laying roller rests, coming into contact with the sheet and ensuring the laying down of the liquid on the sheet; and a crankcase supporting the laying roller, the drawing roller and the contrast cylinder.
- The tank and the drawing and laying rollers are mounted on a support structure hinged to the crankcase, and the deposit group comprises a pneumatic cylinder for controlling the rotation of the tank and the rollers with respect to the contrast cylinder between a working position, in which the laying roller is close to the contrast cylinder, and a machine stop position, in which the tank and the rollers are moved away from the cylinder at a predetermined distance from the contrast cylinder.
- This distance is important in the case of gluing for preventing, during machine stoppage, the sheet, when in contact with the laying roller, from sticking to the same laying roller and/or to the contrast cylinder. Such distance is equal to 25-50 mm so that, irrespective of the thickness of the sheet, said contact between the sheet and the laying roller is prevented.
- The above-mentioned prior art has a few major drawbacks.
- A first drawback is the complex execution of the maintenance or repair operations on the deposit groups known to date.
- In fact, in order to access it, it is necessary to remove the pneumatic control cylinder from the support structure, rotate and overturn said support structure together with the tank, the drawing roller and the laying roller, moving these elements away from the contrast cylinder.
- The above-mentioned overturning of the tank, the drawing roller and the laying roller defines a free area of limited size, which ensures a limited freedom of movement to the operator.
- Another drawback is that, at each restart of production, the pneumatic cylinder takes a few seconds to bring back the laying roller into the working position, and consequently part of the sheet slides along the contrast cylinder before the liquid can be laid down thereon.
- This drawback is important when considering the high feed rate of the sheet and the presence of many metres of unglued/uncoloured sheet.
- The above drawback is further penalising since distributors often reject a lot thus produced due to the presence of non-perfectly glued/coloured rolls.
- This rejection therefore results in a considerable waste of paper and, especially, in a substantial increase in costs.
- In this context, the technical task underlying the present invention is to devise a deposit group, which is capable of substantially obviating the above-mentioned drawbacks.
- Within the scope of said technical task, a major object of the invention is to provide a deposit group, which allows maintenance and repair operations to be performed in a simple and quick way.
- Another important object of the invention is to obtain a deposit group, which avoids the presence of long sections of sheet devoid of gluing, dyeing or other liquid to be deposited.
- The technical task and the specified objects are achieved by means of a deposit group as claimed in the appended claim 1.
- Preferred embodiments are set forth in the dependent claims.
- The features and advantages of the invention will be apparent from the detailed description of a preferred embodiment of the invention, with reference to the accompanying drawings, in which:
-
Fig. 1 shows a deposit group according to the invention; -
Fig. 2a shows a section of the deposit group according to the invention; -
Fig. 2b shows the deposit group in a different configuration; -
Fig. 2c shows a further configuration of the deposit group; -
Fig. 3a shows an assembly in section of the deposit group; -
Fig. 3b shows the assembly ofFig. 3a in a different position; and -
Fig. 4 shows a detail of the deposit group. - In the present document, the measures, values, shapes and geometric references (such as perpendicularity and parallelism), when associated with words like "about" or other similar terms such as "almost" or "substantially", are to be understood as unless measurement errors or inaccuracies due to production and/or manufacturing defects and, especially, unless a slight difference from the value, the measure, the shape, or the geometric reference with which it is associated. For example, these terms, if associated with a value, preferably indicate a difference of not more than 10% of the value itself.
- Furthermore, when used, terms such as "first", "second", "higher", "lower", "main" and "secondary" do not necessarily identify an order, a priority relationship or a relative position, but can simply be used to distinguish more clearly the different components from each other.
- With reference to the aforementioned figures, the deposit group according to the invention, as a whole, is indicated by the numeral 1.
- It is used to deposit a fluid, preferably a liquid (e.g. a glue or a colour) on a raw, preferably
continuous sheet 1a, thus obtaining a processedsheet 1b also preferably continuous. - It should be noted that the expression "raw sheet" simply identifies the sheet before the liquid is deposited thereon by the deposit group 1. The raw sheet differs from the processed
sheet 1b, which in fact comprises theraw sheet 1 a and the liquid deposited thereon. - The deposit group 1 can deposit a (fluid, in detail liquid) glue on the
raw sheet 1a, allowing its gluing to at least an additional, preferablycontinuous sheet 1c. It is therefore capable of gluing together two ormore sheets sheet 1 b comprising said at least twosheets - It should be noted that one or more of the
sheets - Alternatively, the deposit group 1 can be used to deposit a (fluid, in detail liquid) dye on the
raw sheet 1 a so as to form a single processedsheet 1 b exhibiting a writing and/or a coloured image. - The
sheets - The group 1 may be part of a processing line of continuous sheets. This line can comprise multiple deposit groups 1, so as to deposit several liquids and, for example, obtain a processed
sheet 1b with more than two layers or exhibiting a multi-coloured reproduction. - The deposit group 1 is suitable to define a sliding path (highlighted with arrows in
Fig. 2b ) of at least one sheet and therefore may comprise one or more cylinders (described below) suitable for defining the sliding path, and preferably at least partly motorised, so as to control the movement of the at least one sheet along said sliding path. - The deposit group 1 may comprise a
contrast cylinder 2 along which at least oneraw sheet 1a slides; at least onelaying block 3 for depositing at least one liquid on theraw sheet 1a; and, suitably, a control unit suitable to control the operation of the group 1 based on a command given by the operator. - The
contrast cylinder 2 defines a preferably substantiallyhorizontal rotation axis 2a. Thecontrast cylinder 2 can be motorised. - The
contrast cylinder 2 can have on its outer surface a reproduction suitable to be reproduced on theraw sheet 1a. This reproduction is identifiable as a bas/high relief reproducing, for example, dots and/or figures. - In a further alternative, the outer surface of the
contrast cylinder 2 is smooth. - At least in the case of gluing of the
raw sheet 1a to theadditional sheet 1c, the deposit group 1 may comprise aslide cylinder 4 along which theadditional sheet 1c slides before joining theraw sheet 1a downstream of thelaying block 3 with respect to theraw sheet 1a. - It should be noted that in this document the expressions "downstream" and "upstream" are to be understood in relation to the feed directions of the
sheets Fig. 2b . - The
slide cylinder 4 can be motorised. - The
slide cylinder 4 may comprise an additional reproduction formed on the outer surface for the sliding of theadditional sheet 1c, which is suitable to be reproduced on theadditional sheet 1c. This additional reproduction can be somewhat similar to that of thecontrast cylinder 2. - Alternatively, the outer surface of the
slide cylinder 4 is smooth. - The deposit group 1 may comprise a
support structure 5 for thecontrast cylinder 2, the at least onelaying block 3 and theslide cylinder 4, if present. It should be noted that the various cylinders are associated with thestructure 5 in a resolvable manner so as to allow its replacement. - Said
support structure 5 comprises twoside panels 51 suitable to enclose and support thecontrast cylinder 2, the at least onelaying block 3 and theslide cylinder 4, if present. - The
side panels 51 are substantially perpendicular to therotation axis 2a, and suitably vertical. - The
side panels 51 can be anchored to the ground, and in particular they define the only points of anchorage/support of the deposit group 1 to the ground. Consequently, the layingblock 3 is spaced from the ground. - The deposit group 1 may comprise at least one laying block 3 (preferably only one) for depositing at least one liquid, suitably a glue or dye, on at least part of the
raw sheet 1a when it slides on thecontrast cylinder 2. - The laying
block 3 comprises, for each liquid to be deposited, adispenser 31 suitable to dispense the liquid; and at least one roller suitable to withdraw the liquid from thedispenser 31 and to deposit it on theraw sheet 1a; and suitably a feeding apparatus suitable to withdraw the liquid from a tank and bring it to thedispenser 31. - In particular, for each liquid to be deposited, the laying
block 3 may comprise adispenser 31; a drawingroller 32 for withdrawing the liquid from thedispenser 31; and a layingroller 33 interposed between the drawingroller 32 and thecontrast cylinder 2, which is suitable to receive the liquid from the drawingroller 32 and place it on theraw sheet 1a when it slides on thecontrast cylinder 2. - The
dispenser 31 may comprise a chamber containing the liquid, and preferably at least partially filled by the feeding apparatus; and one or more blades suitable to ensure the correct dosage and distribution of the liquid on the at least one roller. - Each

rollers - The
drawing cylinder 32 can be screened and preferably identifiable as an anilox cylinder. - The laying
roller 33 can have on its outer surface a reproduction suitable to be reproduced on theraw sheet 1a. This reproduction is identifiable as a bas/high relief reproducing, for example, dots and/or figures. For example, the outer surface of the layingroller 33 can have radial protrusions (identifiable as rings equally spaced alongaxis 2a, figures or writings) substantially constituting the only deposit points of the liquid on theraw sheet 1a. - Alternatively, the outer surface of the laying
roller 33 is smooth. - The laying
block 3 may comprise asupport frame 34 for thedispenser 31 and the at least oneroller dispenser 31 and the at least oneroller - The
support frame 34 comprises twowalls 341 suitable to enclose and support thedispenser 31 and the at least oneroller - The
walls 341 are substantially perpendicular to the additional axis of the at least oneroller rotation axis 2a. Preferably, thewalls 341 are vertical. - It is noted that the
walls 341 are substantially parallel to theside panels 51. - The distance between the
walls 341 is substantially different from the distance between thepanels 51 so that they can slide reciprocally, and in particular so as to superimpose thewalls 341 onto theside panels 51 with respect to therotation axis 2a. Conveniently, the distance between thewalls 341 is substantially greater than the distance between thepanels 51. - Said distances are calculated along the
rotation axis 2a. - In addition, the laying
block 3 may comprise a distance-adjusting member. - The adjusting member is suitable to vary the distance between the
rollers roller 32 anddispenser 31 with respect to the layingroller 33 preferably along a direction perpendicular to therotation axis 2a, and more preferably to the gravitational gradient. - Alternatively, the adjusting member is suitable to move the
dispenser 31 with respect to the drawingroller 32 by varying the distance between thedispenser 31 and the drawingroller 32, preferably along a direction perpendicular to therotation axis 2a, and more preferably to the gravitational gradient. - Preferably, the adjusting member is adapted to move both said assembly with respect to the laying
roller 33 and thedispenser 31 with respect to the drawingroller 32. - The deposit group 1 may comprise at least one
pressure member 6 for pressing thesheets 1 a and/or 1 c on thecylinders 2 and/or 4. - The deposit group 1 can comprise a
pressure member 6 arranged, with respect to theraw sheet 1 a, upstream of the layingblock 3 and adapted to press theraw sheet 1 a against thecontrast cylinder 2. - Alternatively, the deposit group 1 can comprise a
pressure member 6 arranged, with respect to theadditional sheet 1c, upstream of theslide cylinder 4 and adapted to press theadditional sheet 1c against the saidcylinder 4. - In a further alternative, the deposit group 1 can comprise a
pressure member 6 arranged downstream of the layingblock 3 and adapted to press anyadditional sheet 1c against thecontrast cylinder 2 and hence theraw sheet 1 a, ensuring the gluing of thesheets - Preferably, the deposit group 1 comprises two of said
pressure members 6, and in detail all of the above described threepressure members 6. - Each
pressure member 6 comprises apressure cylinder 61 adapted to press saidsheet 1a and/or 1c against saidcylinder 2 and/or 4; and a kinematic mechanism for moving thepressure cylinder 61 adapted to move thepressure cylinder 61 with respect to thecylinder 2 and/or 4 and thus to adjust the pressure exerted by thepressure cylinder 61 on thecylinder 2 and/or 4. - The rotation axis of the
pressure cylinder 61 of eachpressure member 6 is parallel to and advantageously coplanar with the rotation axis of thecylinder 2 and/or 4. Suitably, the plane on which the rotation axes of thepressure cylinder 61 and of thecylinder 2 and/or 4 lie, against which thepressure cylinder 61 presses thesheet Fig. 2b . - The pressure kinematic mechanism may comprise a
thrust piston 62 that moves thepressure cylinder 61 with respect to thecylinder 2 and/or 4; and an L-shapedlever 63 of the first kind, the ends of which are hinged to thepressure cylinder 61 and thethrust piston 62, which is pivoted to thesupport structure 5. - The deposit group 1 may comprise a
mover 7 adapted to move reciprocally the layingblock 3 and thecontrast cylinder 2, defining for thedeposit group 1a working configuration (Fig. 2b ), in which the working distance between thecylinder 2 and theblock 3 is substantially not greater than the thickness of theraw sheet 1a; and a maintenance configuration (Fig. 2a ) in which the maintenance distance between thecontrast cylinder 2 and thelaying block 3 is greater than the working distance. - The working distance is not greater than 0.1 mm.
- The maintenance distance is substantially equal to at least 0.5 m, preferably substantially comprised between 0.5 m and 1 m, and more preferably substantially equal to 0.7 m.
- The working and maintenance distances are calculated between the
contrast cylinder 2 and the layingroller 33 perpendicularly to therotation axis 2a. - Advantageously, the
mover 7 is engaged with thesupport structure 5 andsupport frame 34, more in particular with thewalls 341 and theside panels 51, mutually constraining theblock 3 and thestructure 5. - It is adapted to move the
laying block 3 with respect to thecontrast cylinder 2 suitably by means of a translation along amovement axis 7a preferably substantially perpendicular to therotation axis 2a. - The
mover 7 comprises at least oneactuator 71 adapted to reciprocally move theblock 3 and thecylinder 2. - The
actuator 71 may be linear and its ends may be constrained to thewalls 341 and thepanels 51, so that it operates said reciprocal motion by varying its elongation. - The actuator, and therefore the
mover 7, are suitable to define stable positions between the layingblock 3 and thecontrast cylinder 2 almost exclusively at its end and start of travel, i.e. at its maximum and\or minimum extension. - They define a stable working configuration in which the
mover 7 and, precisely, theactuator 71 exert a force to maintain the working configuration, which orders the maintenance of the working distance, i.e. a variation in the reciprocal distance between the layingblock 3 and thecontrast cylinder 2, ensuring the correct deposit of the liquid. - Preferably, the
mover 7 and, precisely, theactuator 71 define a stable maintenance configuration in which they exert a force to maintain the maintenance configuration. Theactuator 71 can be pneumatic, electronic or hydraulic. - Preferably, the
mover 7 comprises twoactuators 71, each subtended between awall 341 and theadjacent side panel 51. - The
mover 7 may comprise at least one abutment against which thedeposit block 3 abuts when the group 1 passes into the working configuration. - Said abutment is adjustable by varying the distance between the
deposit roller 33 and thecontrast cylinder 2 on the basis of the thickness of the sheet. - To support the weight of the laying
block 3, themover 7 may comprise at least oneguide 72 integral with thesupport structure 5, and more precisely with theside panels 51; and for eachguide 72, at least oneslider 73 integral with the layingblock 3, and in particular with thewalls 341, and suitable to slide along theguide 72. Preferably, themover 7 comprises twoguides 72 for eachside panel 51; and twosliders 73 for eachguide 72. - The
guide 72 defines a sliding axis for theslider 73 substantially parallel to themovement axis 7a. - The deposit group 1 may comprise at least one
limiter 8 suitable to limit the stroke of themover 7 by reducing the possible mutual spacing between thecontrast cylinder 2 and thelaying block 3 and preventing the maintenance configuration from being reached. - The
limiter 8 enables the group 1 to vary its own configuration between the working configuration and a stationary machine configuration interposed between the working and maintenance configurations, thereby defining a machine stop distance (between thecontrast cylinder 2 and the laying block 3) intermediate between the working and maintenance distances. - In particular, the
limiter 8 defines an active position in which it limits the stroke of themover 7 and the group 1 varies its configuration, suitably exclusively between the working and the stationary machine configurations; and a passive position in which thelimiter 8 does not limit the stroke of themover 7 and the group 1 varies its configuration, suitably exclusively between the working and the maintenance configurations. - It should be noted that the machine stop distance is calculated between the
contrast cylinder 2 and the layingroller 33 perpendicularly to therotation axis 2a. - Suitably, the
limiter 8 is adapted to define a machine stop distance ranging between a maximum value and a minimum value. - The
limiter 8, by preventing at least a further distancing between the layingblock 3 and thecontrast cylinder 2, allows themover 7 to define a stable stationary machine configuration wherein, in fact, thelimiter 8, by preventing a further distancing between theblock 3 and thecylinder 2, causes themover 7 to exploit the blockage provided by thelimiter 8 in order to exert a force to maintain the stationary machine configuration opposing a variation in the distance between the layingblock 3 and thecontrast cylinder 2. - The
limiter 8 can be mechanical and, for example, limit the stroke of themover 7 by engaging thecontrast cylinder 2 with the layingblock 3, and precisely thesupport structure 5 with thesupport frame 34. - Preferably, the deposit group 1 comprises two
limiters 8, each of which suitable to engage aside panel 51 with theadjacent wall 341. - A
limiter 8 may comprise aslot 81 and astop 83, one of which is integral with thesupport structure 5 and the other with thesupport frame 34. - Preferably, the
slot 81 is integral with thesupport structure 5, and in particular with aside panel 51. Thestop 83 is suitable to be integral with thesupport frame 34, and precisely with awall 341. - The
slot 81 has an axis extending substantially parallel to themovement axis 7a. - The
slot 81 may have a length, as calculated along theaxis 7a, at least equal to the maximum value of the machine stop distance so that thestop 83 is able to slide therein along themovement axis 7a over a length substantially equal to the maximum value of the machine stop distance. - It may be formed in the
side panel 51 or in a plate integral with it. - Additionally, the
limiter 8 may comprise anadditional slot 82 integral with thesupport frame 34, and more precisely with awall 341. - The
additional slot 82 has an axis extending substantially parallel to that of theslot 81. - The
additional slot 82 may have a length, as calculated along theaxis 7a, at least equal to the difference between the maximum and minimum values of the machine stop distance so that thestop 83 can slide therein along themovement axis 7a over a length substantially equal to said distance. - The
stop 83 is connected to the control unit so as to be controlled by the same and thus it places thelimiter 8 in the passive or active position based on a command coming from the control unit as described below. - It is suitable to place the
limiter 8 into the active position by fitting into theslot 81 and into the passive position by coming out of theslot 81. In particular, in the active position thestop 83 is inserted in both of theslots stop 83 comes out of theslot 81 and is inserted only in theadditional slot 82. - The
stop 83 comprises apin 831 suitable to fit into theslots shifter 832 suitable to move thepin 831 with respect to theslots Fig. 3a ) and passive position (Fig. 3b ). - In the active position, the
pin 831 is inserted in both of theslots slots 81 and 82 (suitably it is inserted only in the additional slot 82). - The
shifter 832 is suitable to move thepin 831 along atranslation axis 83a substantially perpendicular to themovement axis 7a, and in particular substantially parallel to therotation axis 2a. - The
stop 83 may comprise ananchor plate 833 for anchorage to thewall 341 through constraining means, which are releasable, or in detail resolvable and define a passage hole for thepin 831. - The
anchor plate 833 can thus have screws or bolts. - Said passage hole is substantially shaped against the
pin 831, and in particular theshifter 832. - Moreover, the
limiter 8 may comprise aregulator 84 adapted to enable adjustment, suitably in a continuous manner, of the machine stop distance between a minimum value, greater than the working distance, and a maximum value, smaller than the maintenance distance. - The maximum value is substantially less than 10% of the maintenance distance. It is substantially less than 5 cm, and in detail less than 3 cm. More in detail, it is substantially equal to 2.5 cm.
- The minimum value of the machine stop distance is at least less than 15 times the working distance. It is substantially less than 1 cm, and in detail less than 0.5 cm, and more in detail less than 0.2 cm, and conveniently equal to 0.1 mm. Preferably, the machine stop distance has a minimum value at least equal to 0.1 mm and a maximum value of less than 5 cm.
- To adjust the machine stop distance, the
regulator 84 is suitable to vary the position of anchorage of thestop 83 to thelaying block 3, and in particular to move thestop 83 along themovement axis 7a by adjusting the position of thestop 83 with respect to theslots additional slot 82. - The
regulator 84 may comprise, at each of the resolvable constraining means of theanchor plate 833, an adjustment slot extending substantially parallel to themovement axis 7a, i.e. to theslots - Said adjustment slots are suitable to adjust the machine stop distance on the basis of the position of the passage hole and therefore of the
pin 831 with respect to theadditional slot 82, by modifying the stroke of thepin 831 in theslot 81. - In particular, the operator constrains the
stop 83 so that thepin 831 is at the end of theadditional slot 82 distal to thecylinder 2, and so as to have the minimum value of the machine stop distance. On the contrary, if the maximum value of the machine stop distance is required, the operator places thepin 831 at the end of theadditional slot 82 proximal to thecontrast cylinder 2. Finally, for any intermediate value of the machine stop distance, the operator places thestop 83, and in particular thepin 831, in an intermediate position between those described above. - Finally, alternatively or additionally, it should be stressed that the
regulator 84 can vary the position of at least one of theslots slots - Lastly, the deposit group 1 may comprise at least one
monitoring station 9 for monitoring at least onesheet raw sheet 1 a along the sliding path. - The
monitoring station 9 is suitable to detect an error in the sliding of at least one of thesheets mover 7 does not exert the maintenance force, thereby defining a stop configuration for the deposit group 1 and, advantageously, thelimiter 8 is in the passive position. - The sliding error can identify an error due to non-feeding and/or absence of at least one
sheet monitoring station 9, by detecting its presence but not its feed, sends a sliding error signal. In the second case, themonitoring station 9 sends a sliding error signal if it detects the absence of at least one sheet for example due to a breakage thereof. - Another possible sliding error, precisely in the case of a
multilayer sheet contrast cylinder 2 and thedeposit roller 33 and/or between thewalls 341 and the side panels 51) detected by thestation 9. It is pointed out that themonitoring station 9 can detect distance variations of the order of tenths of mm. - The
monitoring station 9 monitors the passage of the sheet at a point/area of the sliding path, detecting an error in the sliding of at least one of thesheets - The
monitoring station 9 is in data connection with the control unit so as to send said sliding error to said unit and therefore command the transition of the deposit group 1 to the stop configuration. - In the stop configuration, the
mover 7 is ordered not to exert the aforesaid maintenance force, thelimiter 8 is arranged in the passive position and, suitably, the feeding of the sheets along the sliding path is stopped. - In this stop configuration, the
mover 7 does not lock the deposit group 1 in the working configuration and allows a mutual spacing between the layingblock 3 and thecontrast cylinder 2, and in particular a distancing of the layingblock 3 from thecontrast cylinder 2 at a distance greater than the working distance. In detail, as thelimiter 8 is in the passive position, the distancing of the layingblock 3 from thecontrast cylinder 2 can define a distance equal to the maintenance distance. - The
monitoring station 9 can order the discharge of themover 7, allowing an idle distancing of theblock 3. Themover 7 does not exert any force on thelaying block 3 which is free to translate along themovement axis 7a and, as it is lifted from the ground, can move away from thecontrast cylinder 2 as a result of any force external to the group, such as that of the operator and/or of the pressure of the sheets on thecontrast cylinder 2 or on another component of the group 1. - Alternatively, the
monitoring station 9 can order themover 7 to reverse its action and to exert a force for moving the layingblock 3 away from thecontrast cylinder 2. Preferably, themonitoring station 9 can order themover 7 to place the group 1 into the maintenance configuration. - To control the sliding of the processed
sheet 1 b, the deposit group 1 may comprise amonitoring station 9 located downstream of thecontrast cylinder 2. - To monitor the sliding of the
raw sheet 1a, the deposit group 1 may comprise amonitoring station 9 located upstream of thecontrast cylinder 2, and in particular of thecorresponding pressure cylinder 61. - To check the sliding of the
additional sheet 1c, the deposit group 1 may comprise amonitoring station 9 upstream of theslide cylinder 4. - Advantageously, the deposit group 1 can check the sliding of all the
sheets monitoring stations 9. - In addition to or replacement of one or more of said three
stations 9, the deposit group 1 may comprise amonitoring station 9 adapted to measure a change in distance between thecontrast cylinder 2 and theblock 3 and available at thecontrast cylinder 2; and/or amonitoring station 9 adapted to measure a change in distance between therollers deposit roller 33. - The operation of the deposit group, described above as regards structure, is described below.
- Initially, the group 1 is in the maintenance configuration (
Fig. 2a ) and thestop 83 is in the passive position (Fig. 3b ). - The operator, by exploiting the
regulator 84, constrains thestop 83 to thewall 341, placing thepin 831 into a position relative to theadditional slot 82 such that, with thelimiter 8 in the active position, there is a certain machine stop distance. - Once the adjustment of the machine stop is completed, the operator orders the transition to the working configuration (
Fig. 2b ) and arranges thestop 83 into the active position (Fig. 3a ). - In particular, the operator, thanks to the
mover 7, brings the layingblock 3 close to thecontrast cylinder 2, superimposing theadditional slot 82 and thepin 831 onto theslot 81, and commands the insertion of thepin 831 in both of theslots - At this point, it orders the transition of the deposit group 1 to the stationary machine configuration (
Fig. 2c ). - In particular, the
actuator 71 extends, moving the layingblock 3 away from thecontrast cylinder 2. Thepin 831 slides in theslot 81 and, by abutting against the end of theslot 81 distal to thecontrast cylinder 2, blocks the extension of theactuator 71, thereby preventing a further advance of the layingblock 3 and the reaching of the maintenance configuration. - The deposit group 1 is in the stationary machine configuration (
Fig. 2c ). - At the beginning of the processing of the
sheets Fig. 2b ). - The
sheets mover 7 brings thedeposit roller 33 close to thecontrast cylinder 2, allowing the deposit of the liquid on theraw sheet 1a. - The transition to the working configuration brings the
pin 831 close to the end of theslot 81 proximal to thecontrast cylinder 2. - The operator, when performing maintenance, brings the
limiter 8 into the passive position (Fig. 3b ) causing thepin 831 to come out of theslot 81 so that it is only inserted in theadditional slot 82. - At this point, the operator orders the transition of the group to the maintenance configuration (
Fig. 2a ). - The transition to the passive position causes the
mover 7, since its stroke is not limited bylimiter 8, to fully extend and place the layingblock 3 at the maintenance distance from thecontrast cylinder 2. - Lastly, if one or more of
monitoring stations 9 does/do not detect the passage of thesheet 1bsheet 1a, it/they sends/send a sliding error signal to the control unit. In response to the signal, the control unit commands the transition to the stop configuration, and in particular it orders themover 7 to stop the maintenance force and thestop 83 to pass into the passive position. - The invention provides significant advantages.
- A first advantage is the presence of the
monitoring station 9 which, by detecting an incorrect paper flow, blocks the group, thereby preventing breakdowns thanks to the cessation of the maintenance force that moves theblock 3 away from thecontrast cylinder 2, avoiding accumulations. - This aspect brings the
deposit block 3 close to thecontrast cylinder 2 in complete safety, minimizing the machine stop distance, by adjusting it to the thickness of the sheet being processed, and therefore the transition time from the stationary machine configuration to the working configuration. - Another advantage is that the deposit group 1 reduces the ratio of liquid-free sheets, thus avoiding waste from production by distributors.
- A non-secondary advantage is that, in the maintenance configuration, the laying
block 3, compared to the known groups, has an increased distance from thecontrast cylinder 2, thus ensuring a large operating/intervention space. - Another advantage is that the deposit group 1, being fully anchored to the
support structure 5, is transportable already assembled. - The invention is susceptible of variations falling within the scope of the inventive concept, as specified in the independent claims, and of the related technical equivalents. In this context, all details are replaceable by equivalent elements and any type of materials, shapes and dimensions may be present.
