Substantially such machines consist in oval shaped baths inside of which the dyeing bath is circulated through a predisposed paddle moving mechanism which allows the garments immersed in the dyeing bath to follow the impressed circulation movement.
- the dyeing process "on yarn” substantially provides for the use of two technologies of a different kind, according to which the dyeing of the yarn occurs when the same is wound in reel or in skeins.
- the arrangement of the reels to be dyed are in suitable pressurized autoclaves where the dyeing bath is moved and forcedly circulated between the reels to be dyed.
- the dyeing method providing for the use of skeins is particularly employed in the tinting of wool yarns of the thin and delicate type. Substantially, the yarn skeins, aligned in rows, are set inside suitable cabinets being sustained by suitable rods, where the dyeing bath is forcedly circulated between the arranged skeins. Another used process is that providing for the dyeing of the woollen fabric in opened or tubular fabric.
- an autoclave inside of which the material to be dyed in the form of contiguously seamed "patches" forming a sort of rope seamed at the ends is placed circulating in the dyeing bath as well as the material to be dyed.
- the fabric in the form of head-tail seamed rope is closed on the outside of a reel and, by means of the rotational motion of the reel, the rope of fabric is moved in the area of the autoclave following a forced circuit.
- the reel is placed on the upper part of said forced circuit and just before the injection point of the dyeing bath is located in such a way that the fabric is coloured passing through such point.
- the dyeing bath is provided for placed in the underside of the autoclave and part of it circulates together with the fabric.
- the injection of the bath in the dyeing point usually occurs by means of circulation pumps or systems conventionally defined "jet".
- a first solution can be found in US2002/0017118 (Held et al. ) in which a type of drum for a fabric dyeing machine is illustrated.
- the solution provides a drum subdivided in sections according to a radial partition.
- the provided partitions are connected to the walls of the drum through narrow perforated walls through which the dyeing liquid is discharged.
- the wall of the drum and the provided partitions on the contrary have no perforations.
- Said partitions are connected to a perforated pipe placed at the centre of the drum through which the introduction of the dyeing liquid is provided.
- a second solution is described in W02004/044300 (Arizzi ) in which a machine for treating fabric immersed in a bath is described, particularly for the dyeing of clothes.
- the machine includes a rotating drum defining a charging compartment in which the clothes to be treated are placed, where further a sealing closed outer wall is present in order to avoid letting the dyeing bath exit.
- JP2004060107 (Takigawa ) in which a rotating drum type apparatus for treating textile fibres is described.
- the declared aim of the invention aims to realize a delicate dyeing bath without the use of a pump for the movement of the dyeing bath itself.
- the claimed apparatus provides for the charging of the apparatus itself with the textile fibres to be treated with the dyeing within a first drum similar to an internal cylinder rotationally installed relatively to a horizontal shaft in an external drum.
- the solution provides a lot of paddles for the liquid collection interposed between the internal drum and the external drum in a block at the rear end of the internal drum.

Abstract
Description
- This invention has as object an apparatus for dyeing delicate garments.
- The invention, finds particular but not exclusive application in the field of the production of devices for dyeing fabric, particularly fabric and garments made with delicate fabric.
- Dyeing techniques for fabric and yarns have been known and diffused for some time. In extreme synthesis the dyeing process provides the bestow of a colour different from the one that would be the natural colour of the yarn or fabric transferring the colouring from the dye bath to the fibre, so as to distribute it uniformly and steadily fix it. The state of the art provides different dyeing possibilities according to the fact that the dyeing is respectively performed: on patch, on fibre, on paste, on yarn or on garment. Substantially, the dyeing process "on patch" consists in dyeing the fabric once its weaving phase is completed, as for the dyeing process "on fibre", the painting is carried out on tapes of fibres later coupled, ironed and submitted to spinning. The dyeing process "on paste", that occurs on chemical fibres, sees that the dyeing is carried out adding some coloured pigments to the paste to be extruded in such a way that after the extrusion coloured yarns are obtained. In the dyeing process "on yarn", the yarn itself, wound in reel or in skein, is provided for submission to the dyeing operation so as to obtain the homogenous colouring of the yarn itself. Finally, the dyeing process "on garment", at present obtaining results with scarce value, provides immerging off-the-pegs in a dye bath. Referring to the off-the-peg dyeing, particularly of items in wool such as sweater or outerwear, the results of current dyeing processes revealed to be little appreciable because of the noteworthy difficulties encountered for obtaining a quality finished product. In the present state of the art, with reference to knitted garments, the dyeing methods substantially are of three kinds. A first method provides the dyeing of the finished garment by means of the use of machines conventionally defined of the "Dutch" type. Substantially such machines consist in oval shaped baths inside of which the dyeing bath is circulated through a predisposed paddle moving mechanism which allows the garments immersed in the dyeing bath to follow the impressed circulation movement. The dyeing process "on yarn" substantially provides for the use of two technologies of a different kind, according to which the dyeing of the yarn occurs when the same is wound in reel or in skeins. If the dyeing of the yarn occurs when the same is wound in reels, the arrangement of the reels to be dyed are in suitable pressurized autoclaves where the dyeing bath is moved and forcedly circulated between the reels to be dyed. The dyeing method providing for the use of skeins is particularly employed in the tinting of wool yarns of the thin and delicate type. Substantially, the yarn skeins, aligned in rows, are set inside suitable cabinets being sustained by suitable rods, where the dyeing bath is forcedly circulated between the arranged skeins. Another used process is that providing for the dyeing of the woollen fabric in opened or tubular fabric. To carry out such a type of working an autoclave is used, inside of which the material to be dyed in the form of contiguously seamed "patches" forming a sort of rope seamed at the ends is placed circulating in the dyeing bath as well as the material to be dyed. Substantially, the fabric in the form of head-tail seamed rope is closed on the outside of a reel and, by means of the rotational motion of the reel, the rope of fabric is moved in the area of the autoclave following a forced circuit. The reel is placed on the upper part of said forced circuit and just before the injection point of the dyeing bath is located in such a way that the fabric is coloured passing through such point. The dyeing bath is provided for placed in the underside of the autoclave and part of it circulates together with the fabric. The injection of the bath in the dyeing point usually occurs by means of circulation pumps or systems conventionally defined "jet".
- In the known present state of the art, there are multiple traceable solutions in patent literature about machines or improvements to machines for dyeing yarns and/or fabrics with particular reference to the solutions with a basket for the positioning of the material to be treated. Merely as an example, a first solution can be found in
US2002/0017118 (Held et al. ) in which a type of drum for a fabric dyeing machine is illustrated. In short, the solution provides a drum subdivided in sections according to a radial partition. The provided partitions are connected to the walls of the drum through narrow perforated walls through which the dyeing liquid is discharged. The wall of the drum and the provided partitions on the contrary have no perforations. Said partitions are connected to a perforated pipe placed at the centre of the drum through which the introduction of the dyeing liquid is provided. - A second solution is described in
W02004/044300 (Arizzi ) in which a machine for treating fabric immersed in a bath is described, particularly for the dyeing of clothes. Briefly put, the machine includes a rotating drum defining a charging compartment in which the clothes to be treated are placed, where further a sealing closed outer wall is present in order to avoid letting the dyeing bath exit. - Another solution is present in
JP2004060107 (Takigawa - Furthermore, with particular reference to the technical field of dyeing apparatuses, in patent literature the following solutions are pointed out:
- D1
US4111104 (Ikeda Yoshio ), - D2
US5950459 (Takagi Shinya ), - D3
US298691 6 (John Bochan ) - In D1 a washing machine comprising: an outer casing open at a top end thereof; a cylindrical washing tub coaxially disposed in said outer casing and rotatable about a fixed vertical axis, said washing tube formed with (1) a constant diameter upper peripheral wall section located at an upper region thereof, and (2) a stirring member, provided beneath said upper peripheral wall section and separately rotatable therefrom, with the only portion of said washing tub that is above a top-most end of said stirring member being said constant diameter upper section, said stirring member extending substantially halfway up the height of said washing tub, and having an inner peripheral surface formed such that its diameter gradually linearly increases from its lower portion toward its upper portion; and means for rotating: (a) said stirring member and said tub together during a dehydration operation, and (b) said stirring member alternately in opposite directions during a washing operation while holding said tube stationary, said stirring member thereby rotating a bottom-most portion of said washing machine, while said upper peripheral wall remains stationary, which washes laundry due to the friction between the laundry and the rotating stirring member, and between the rotating laundry and the stationary upper peripheral wall, the varying diameter of said stirring member causing vertical motion of said laundry and increasing the washing effect.
- In D2 an electric washing machine, comprising: a washing machine body; a water tank having a bottom surface with an opening and fixed in said washing machine body; a double-cylindrical axes body formed of outer and inner rotary axes passing through said opening of said water tank bottom surface; a washing tank attached to an upper end of said outer rotary axis, arranged in said water tank, and having a large number of dehydration holes through a sidewall of said washing tank; a container type agitator attached to an upper end of said inner rotary axis, arranged at a bottom of said washing tank, and having a shape which is open upward; a planetary gear mechanism coupled to a lower end of said double-cylindrical axis body, said planetary gear mechanism including an input axis, a planetary gear outer periphery portion fixed to said outer rotary axis, and a group of planetary gears coupled to said inner rotary axis, engaging with an outer periphery of said input axis and an inner surface of said planetary gear outer periphery portion, and rotating in a group around said input axis; an electric motor and power transmission mechanism for rotatably driving said input axis; and a brake arranged near an outer periphery of said planetary gear outer periphery portion, releasing said planetary gear outer periphery portion at least during washing, and clamping said planetary gear outer periphery portion during dehydration.
- In D3 a vertical axis laundry machine comprising: a basket formed as an inverted cone open at its top; a tub surrounding said basket and extending above and over said basket; means for rotating said basket and tub together at a speed sufficient to fling clothes and liquid outwardly over the edge of said basket; means for holding said tub stationary during rotation of said basket, said tub being formed to guide clothes and liquid inwardly over said basket when said tub is stationary and said basket is rotating; said tub having openings formed therein for removal of liquid from said basket during rotation of said basket and tub together ; means for reciving and draining liquid passed through said openings during rotation of said basket and tub together; and means controlling said tub holding means, said machine providing a washing operation during rotation of said basket alone and providing a centrifugal extraction operation during rotation of said basket and tub together.
- All these things considered it is therefore reasonable to consider known:
- fabric dyeing apparatuses provided with a perforated moving basket in a dyeing bath;
- fabric dyeing apparatuses provided with an internal moving basket and an external basket;
- fabric dyeing apparatuses provided with devices in order to obtain a cascade effect.
- dyeing apparatuses with double vertical rotation axis
- All said solutions have, though in different measures, drawbacks and/or limitations.
- A first characteristic limitation of all of the known solutions for fabric dying apparatuses consists in the present impossibility to proceed to a quality dyeing of the outerwear and in particular of the finished garment made with delicate fabric such as, for example, wool.
- A second limitation, also involving all of the known solutions for fabric dying apparatuses, in the opinion of the applicant, consists in the verified difficulty of dyeing finished garments, particularly if they are made using delicate fabric. In fact it has been noticed that at present it is impossible to eliminate the disadvantage given by the mechanical action exercised by the movement of the fabric against the walls of the basket with consequent abrasion problems, anomalous tensioning of yarns, matting, permanent creases formation and possible formation of "striations".
- Another limitation consists in the fact that the known current solutions for fabric dying apparatuses not obtaining noteworthy results on finished garments determine a considerable lengthening of the confection time of the garment often creating problems related to the stock remnants of dyed yarns or fabrics with negative consequent repercussions regarding the overall costs of the product.
- The drawbacks found in the illustrated solutions of dyeing apparatuses are as much numerous as the previous ones.
- Particularly concerning the solution illustrated in D1:
- The provided frusto-conical shape of the agitator (stirring member) whose intake diameter is greater with reference to that of the base, causes, as an effect of the rotation of the same, the linen content placed inside it to be pushed also upwards and toward the walls of the washing container (washing tub) consequently causing a friction effect on the linen items. This characteristic is particularly disadvantageous in the tinting treatment, notably of delicate items where the friction effects must be minimized.
- The substantially frusto-conical shape provided for the agitator (stirring member), whose intake is lacking in any type of front wall opposite to the bottom wall, does not allow to assimilate said agitator to a drum in the strict sense of the word. In this way, said shape of the agitator does not allow its use with the axis in a horizontal position because the items placed inside it would inevitably slide on the washing tank damaging them. Furthermore, the same configuration does not allow said agitator to be usefully used in a dyeing apparatus, particularly for delicate items, because the shape of the same and its necessary positioning would not allow an optimal distribution of the dyeing liquid on the items to be dyed.
- The washing container (washing tub) is not provided with blades. In this way, such structured washing container is not allowed to be usefully used in a dyeing apparatus for delicate items because it's not suitable to correctly move the dyeing liquid. Furthermore, such a structure does not allow to obtain any shower effect on the items to be dyed.
- The pointed out structure of the washing-machine requires the washing container (washing tub) and the agitator (stirring member) to be placed in a vertical position, otherwise there will be a substantial missed functionality of the agitator (stirring member), and it requires the movement and support axes of the same to be vertical as well, which is also a claim object. In this way, said structure precludes a useful operation in the case of a transposition of the D1 patent solution in the field of the dyeing apparatuses for delicate items in the case in which the positioning of the washing container and the positioning of the agitator were placed in a horizontal position because inevitable damages of the items to be treated would occur.
- Providing the rotation mechanism of the washing container and of the agitator, which are put in motion by a single motor, does not allow a wide rotational modulability of the washing container and of the agitator, the one independently; from the other, said rotational modulability being required in a dyeing apparatus, particularly for delicate items, on the one hand, in order to obtain an optimal dyeing liquid circulation and on the other hand in order to obtain a motion as lower as possible of the items themselves.
- Particularly concerning the solution illustrated in D2:
- The plurality of projections of which the wall of the washing tank is internally provided are shaped in such a way as to provide a rectangular planar shape extending in the vertical direction and having rounded corners of a few millimetres in height. Furthermore, it is provided that the projection may be of any shape as do as it causes friction between the laundry and washing tank and it does not causes damage to the laundry. In this way, the transposition of such a solution in a dyeing apparatus, particularly for delicate items, would be disadvantageous because said shape of the provided projections is not suitable to induce a suitable movement of the dyeing liquid. Furthermore, the D2 patent solution, providing that, being the shape given to said projections of any other type, it must be constrained in order to cause a friction between the linen and the washing tank said friction not causing damages to the linen itself, limits the shape of said projections to the stated purpose of destination, which purpose is anyhow incompatible with the same purpose for which a dyeing apparatus for delicate items is made, in which it's important for the items to be treated not to be subject to friction.
- The provided container type agitator provided at the lower portion inside washing tank have a curved surface as a hemispherical shell or cycloid which is open upward above. The provided shape of the agitator does not allow to assimilate said agitator to a drum in the strict sense of the word. In this way, said shape of the agitator does not allow its use with the axis in a horizontal position because the items placed inside it would inevitably slide on the washing tank with easily predictable damages to the same.
- The pointed out structure of the washing-machine requires the washing container (washing tank) and the agitator (container type agitator) to be placed in a vertical position, otherwise there will be a substantial missed functionality of the agitator (container type agitator). In this way, said structure precludes a useful, operation in the case of a transposition of the D2 patent solution in the field of the dyeing apparatuses for delicate items in the case in which the positioning of the washing container and the positioning of the agitator were placed in a horizontal position.
- Furthermore; the rotation of the washing container (washing tank) and of the agitator (container type agitator) carried out by a single motor with the interposition of a planetary gear mechanism coupled to a lower end of the double-cylindrical axis body, does not allow a wide rotation modulability of the washing container and of the agitator, the one independently from the other, said rotational modulability being required in a dyeing apparatus, particularly for delicate items, on the one hand, in order to obtain an optimal dyeing liquid circulation and on the other hand in order to obtain a motion as lower as possible of the items themselves.
- Particularly concerning the solution illustrated in D3:
- The D3 patent provided structure of the washing-machine with a vertical axis, essentially comprising a basket formed as an inverted cone open at its top; a tub surrounding said basket and extending above and over said basket; means for rotating said basket and tub together at a speed sufficient to fling clothes and liquid outwardly over the edge of said basket; means for holding said tub stationary during rotation of said basket, although it is suitable for purpose for which a washing apparatus is intended, even taking into consideration such a domain only, the D3 proposed solution, generating a sometimes considerable friction effect, for sure is not to be considered suitable for washing delicate items because it would cause their fast deterioration. Given said structure, the transposition of the D3 patent solution in the field of the dyeing apparatuses, particularly for delicate items, can hardly be supposed because, on the one hand the shape of the basket formed as an inverted cone open at its top and of said tub surrounding said basket does not allow a correct circulation of the dyeing liquid, as well as a correct positioning and a correct movement of the items to be dyed.
- Furthermore, the provided rotation in the same direction and at the same speed of the basket formed as an inverted cone open at its top and of said tub surrounding said basket is a disadvantageous circumstance for the dyeing process because it s not suitable to ensure the homogeneity of the dyeing itself on the items to be dyed.
- Furthermore, providing a single motor and the described rotation mechanism for the basket and the tub, does not allow a wide rotation modulability of said elements the one independently from the other, said rotational modulability being required in a dyeing apparatus, particularly for delicate items, on the one hand, in order to obtain an optimal dyeing liquid circulation and on the other hand in order to obtain a motion as lower as possible of the items themselves in order to avoid abrasion problems, anomalous tensioning of yarns, matting, permanent creases formation and possible formation of "striations".
- It is therefore necessary for the enterprises of the field to find optimal solutions to obtain the following set aims.
- These and other aims are reached by this invention according to the characteristics as for the included claims, solving the abovementioned problems by means of an apparatus for dyeing delicate garments including a body (2) equipped with a dyeing bath containment basin (3) within the dyeing basin there being a drum (4) hinged to a rotational hollow shaft (43) provided with a lot of bath movement paddles (44), where internally to the drum (4) there is a basket (7) whose rotational axis is housed inside the hollow shaft (43) of the drum (4) where a pulley is keyed to the rotational hollow shaft (43) of the drum (4) and a pulley is keyed to the rotational axis of the basket (7), each pulley being conventionally moved by means of belts by independent electric motors in such a way that the movement of the drum (4) and the movement of the basket (7) are independent.
- By means of the considerable creative contribution whose effect constitutes an immediate technical progress different aims and advantages are achieved.
- A first advantageous aim consists in the realization of an apparatus for dyeing delicate garments thanks to the innovative structuring of which a finished garment optimal dyeing can be realized also and particularly in the case in which the confection of the same has been made using delicate fabric.
- A second advantageous aim consists in the realization of an apparatus for dyeing delicate garments with the innovative structuring which allows for the solving of the current models' problems regarding the dyeing of delicate garments, particularly preventing their characteristic drawbacks allowing for the avoidance of the mechanical rubbing of the garment and the consequent arising damages, as well as avoiding the dyeing process causing damages to the garment made with delicate fibres due to the occurring of an anomalous tensioning of yarns rather than to problems concerning matting, forming of permanent creases or due to the formation of striations of anomalous colouring.
- A third advantageous aim consists in the realization of an apparatus for dyeing delicate garments with the innovative structuring which obtains an optimal dyeing of woolen garments or garments made with other delicate fibres, as well as of those made knitted and items in fabric.
- One more advantageous aim consists in the realization of an apparatus for dyeing delicate garments whose innovative structuring, allowing for the dyeing directly on the finished garment, allows the finishing treatments to be carried out directly on the raw fabric.
- A last advantageous aim consists in the realization of an apparatus for dyeing delicate garments whose innovative structuring remarkably reduces the processing times of the confectioned garment avoiding the drawbacks deriving from the necessary waste of coloured material following the confectioning and, furthermore, allowing for the product cost contain.
- These and other advantages will appear from the following detailed description of some preferred embodiments with the aid of enclosed schematic drawings whose embodiment details are not to be considered limitative but only illustrative.

Figure 1 , is a sectional view of the apparatus for the dyeing of delicate garments regarding the invention object of this invention; -
Figure 2 , is a sectional view along the axis A-A of the apparatus for the dyeing of delicate garments offigure 1 . - With reference to the figures one can observe an
apparatus 1 for the dyeing of delicate garments the base solution of which as described in the disclosed example (fig. 1 andfig. 2 ) includes a weight-bearing body (2) conventionally realised in such a way as to encompass and be suitable for the allocation of the functional components of the apparatus and of the devices and controls that conventionally integrate the functioning. More in detail, the body (2) is provided to comprise a basin (3) for the dyeing bath containing, the basin (3) conventionally provided with an opening (31) suitable for allowing the loading of the apparatus (1) with the garments to be dyed. - Inside the provided basin (3) the apparatus (1) there is a cylindrical drum (4) including a perforated cylindrical perimetrical wall (41) being provided with a lot of through-holes on the whole surface, conventionally but not necessarily equidistantly located one with respect to the other usually, but not necessarily, being placed in parallel rows. Conventionally, the cylindrical perimetrical wall (41) is orthogonally connected and sustained by a circular bottom wall (42). The bottom wall (42) of the drum (4), at the centre, has a through-hole (421).
Furthermore, the bottom wall (42) of the drum (4), in order to make rotational motion of the same possible, keys a rotational hollow shaft (43). - The hollow shaft (43), in the drum (4), is to be placed at a shaft-carrying body (21) which is in the body (2) of the apparatus (1). The provided shaft-carrying body (21) realizes a passing-through housing (211), conventionally realized in such a way that it is able to allow the axial holding of the hollow shaft (43) regarding the drum (4), where the holding of the hollow shaft (43) to the shaft-carrying body (21) occurs by means of the interposition of friction reduction devices conventionally such as antifriction bearings (5). The obtained housing (211) of the shaft-carrying body (21) of the body (2) is such that it is centrally positioned relatively to the back wall (31) of the basin (3), in such a way that the drum (4) is centred relatively to the basin (3) itself, the basin (3), in the example, being shaped in such a way as to be cylindrical.
- In order to be able to give the drum (4) a rotational movement, that can be in clockwise as can be anti-clockwise, there is a pulley (6), keyed at the rear end of the hollow shaft (43), opposite the end connected to the bottom wall (42), conventionally keyed to the hollow shaft (43). Indifferently the rotational motion of the drum (4) can be carried out also by means of different, conventional, systems for the transmission of the motion to the hollow shaft (43) such as, for example, gears. The cylindrical perimetrical wall (41) of the drum (4) has further, at the internal surface, a series of paddles (44) which, in the example described as preferred embodiment, are identically shaped, radially arranged and each of them extending for the entire length of the cylindrical perimetrical wall (41) itself.
- More in detail, each paddle (44) is shaped in such a way as to be shaped as a rectangular plate, where each paddle (44) is to be positioned parallel with respect to the contiguous paddle (44). However, there is also the possibility for each paddle (44) profile to be shaped differently with respect to the rectangular shape provided in the basic solution, likewise the reciprocal positioning of each paddle (44) may also not be parallel. Moreover, there is the possibility for the provided paddles (44) to also be arranged so that not all of them are on the same plane being positioned in a scalar way and/or alternative scalar way.
- Internally to the drum (4), axially to the same, there is a cylindrical basket (7), able to contain the garments to be treated, shaped in such a way as to comprise a cylindrical wall (71) conventionally perforated in order to allow the passage of the dyeing liquid, at the external edge of which there is an orthogonal closed circular bottom (72), oppositely to this circular bottom (72) conventionally there is a front wall (73), with a central opening (731) the latter, near the edge, having a protruding reinforcing edge (732) in such a way that through the provided central opening (731) the loading of the basket (7) with the garments to be treated is conventionally allowed.
- Centrally joined to the circular bottom (72) of the basket (7), there is a rotational axis (74) for the support and the movement of the basket (7). More in detail, the axis (74) of the basket (7), by means of the interposition of friction reduction devices conventionally such as some antifriction bearings (5), is placed internally to the hollow shaft (43) of the drum (4), the axis (74) of the basket (7) being provided to be centred relatively to the inside of the hollow shaft (43) in such a way that, on its part, the basket (7) is centred relatively to the drum (4). Furthermore, the axis (74) of the basket (7) has a length which is relatively greater than the length of the hollow shaft (43) in such a way that the rear end of the axis (74) itself on the side protrudes from the hollow shaft (43) of the drum (4). In order to be able to give the basket (7) a rotational motion, which is established to be possibly both in clockwise as anti-clockwise, a pulley (6), conventionally keyed to the axis (74), is provided to be keyed at the end of the axis (74) exiting from the hollow shaft (43) of the drum (4). In the same way as provided for the drum (4), indifferently the rotational motion of the basket (7) is provided to be able to be made also by means of different, conventional systems for the transmission of the motion such as, for example, gears. As the rotational motion of the drum (4) as the rotational motion of the basket (7) are allowed by means of independent electric motors, each of them being connected to the related pulley (6), in the embodiment example described, conventionally by means of driving-belts. As disclosed in
figure 1 and infigure 2 the drum (4) as well as the basket (7) are horizontally placed. - Furthermore, the cylindrical wall (71) of the basket (7) internally has protrusive walls (75) radially arranged conventionally being shaped in such a way that the orthogonal section of the same is shaped as a trapezium and that they are equidistantly placed the one from the other whether or not being perforated. In the preferred solution that will be described, the distance intercurring between the cylindrical perimetrical wall (41) of the drum (4) and the cylindrical wall (71) of the basket (7) is provided to preferably be contained between 5 and 10 centimetres, while the distance intercurring between the cylindrical perimetrical wall (41) of the drum (4) and the circular wall of the basin (3) is provided to preferably be 3 centimetres.
- Furthermore the apparatus (1) is provided to have, mounted externally to the machine body, a heat exchanger consisting of a plate provided with a series of pipes inside of which a fluid at a controlled temperature is circulated, whose provided heat exchanger is placed outside at the underside of a wall of the body (2) in order to be able, by means of thermal conduction, to heat or cool the dyeing bath.
- Operatively, the basin (3) contains the dyeing bath whose level is such as to reach at least the lower end of the basket (7). The dyeing bath circulation is ensured by means of the rotation of the drum (4) that, preferably rotating at a rotational speed between 150 and 200 revolutions per minute, allows, thanks to the action of the paddles (44) with which the drum (4) itself is provided, to generate a bath vortex in such a way that the dyeing liquid is pushed by the drum (4) itself towards the walls of the basin (3) the latter generating a counter-pressure effect of the dyeing liquid in such a way that the same will be repelled inwardly being forced toward the drum (4) and the basket (7). In consequence of the effect generated by the rotation of the drum (4), the dyeing bath will be forced to go beyond both the cylindrical perimetrical wall (41) of the drum (4), as the cylindrical wall (71) of the basket (7) so as to create a shower effect able to penetrate the fibres of the contained garments in the basket (7) itself, though the item remaining substantially still. However, in order to allow for the minimum movement of the garments, the possibility for the basket (7) to be allowed a slow rotational motion is provided, directed in the same or in the opposite direction with respect to the rotational motion in the drum (4).
