Description

The device and method of sedimentary ripple silk thread on a receiving surface

Technical field

The present invention relates to tire manufacturing arts.

More particularly it relates to the sedimentary ripple silk thread on cylindric deposition surface (such as tire base).

Background technique

Tire or cover tire be understood to be intended to be mounted on wheel rim through vulcanized article.

Tire base is understood to that before vulcanization, (semi-finished product can by each semi-finished product of assembling rubber plies form Can be enhanced or compound with other semi-finished product) and rubber-moulding element (the rubber-moulding element may with compound each other) and Metal beads line etc. and formed intermediate products.

In order to which sedimentary ripple silk thread, first method may include before depositing to the receiving surface on a receiving surface Assign silk thread corrugated shape.

This is described in document EP 0976538, and the document discloses the method for being used to prepare radial carcass casing ply, In the silk thread with corrugated shape is deposited on rubber strip.In first variant form shown in Fig. 1, in flat rubber Sedimentary ripple silk thread on item.In second variant form shown in Fig. 2, sink on the rubber strip shaped in cylindrical core in advance Product soie ondée.In one of these variant forms or another one, the uncinus being mounted on belt can deposited extremely Silk thread corrugated shape is assigned before rubber strip.

First of precipitation equipment described in the document EP 0976538 is the disadvantage is that be not suitable for a part in tire base Sedimentary ripple silk thread on width.

This is because uncinus must be positioned at the outside of rubber strip in one of variant form proposed or another one Or boundary can just cause to be fully rotatable to discharge silk thread after depositing soie ondée to rubber strip, and especially will not Influence the deposition quality of silk thread.

Another in the document EP 0976538 is the disadvantage is that, silk thread must slide depositing on uncinus It is endowed corrugated shape before.Therefore, uncinus used in the document EP 0976538, which is not suitable for deposition, has certain journey The silk thread of the viscosity (such as due to being coated with rubber coating) of degree.Not only due to silk thread be adhered to uncinus slowed down deposition or Person causes not can be carried out deposition, and uncinus may damage silk thread and its coating.

Finally, another of the document EP 0976538 by soie ondée the disadvantage is that, deposit to cylindric rubber Before item, the ripple of silk thread is formed in the planes.Therefore it needs that uncinus is made to advance around loop, the loop packet At least one linear segment and at least one bending or circular portion are included, the bending or circular portion allow uncinus to be back to Linear segment.The arrangement of the loop with linear segment and bending part may limit the movement speed of uncinus, Therefore the deposition velocity of soie ondée is limited.

In addition, another document EP 1208963, which is disclosed, is more suitable for the sedimentary ripple silk thread on a part of width of tire base Equipment.

Since the purpose of the document EP 1208963 more specifically prepares the so-called zero degree casing ply in tire, So that enhancing silk thread is wound for several times around tire base.

Since the silk thread for being used to prepare zero degree casing ply is inextensible, the document EP 1208963 proposes the ripple of silk thread Deposition.

Ripple deposition be understood to mean such method: by make across the deposition surface silk thread along traveling wave lines diameter to Deposit silk thread, the ripple deposition with the above method the difference is that, silk thread is endowed corrugated shape before the deposition.

It is deposited by means of the ripple, it is described to be therefore capable of increasing the straight of tire base beyond length to deposit silk thread beyond length The risk of the silk thread stretching, extension or fracture of deposition may be not present in diameter.More specifically, during tire base diameter increases, the wave of silk thread Line amplitude reduces, and silk thread straightens in the circumferential direction of tire base, and the diameter of every circle silk thread around tire base deposition increases.

In order to carry out the ripple deposition of silk thread on tire base, the document EP 1208963 proposes a kind of bringing device, institute Stating bringing device includes the device for transmitting silk thread, for making the device of silk thread transverse shifting, and for silk thread to be laid with Device on tire base.

More specifically, the device for transmitting silk thread includes entering pulley, it is described to guide silk thread to capstan winch into pulley, The rotation speed of the capstan winch is subordinated to the rotation speed of tire base to control the wire length of the every circle transmission of tire base, mobile device Seeker including swing connecting bar form installs two silk threads in the swing connecting bar and guides roller bearing, and laying apparatus is It is laid with the form of roller bearing, the laying roller bearing is installed into be rotated freely around the axis for being parallel to tire base rotation axis.

In order to which the ellipse for describing to turn to silk thread laterally is mobile, swing connecting bar is via articulated linkage and rotatable bar It is mounted on the end of rotary shaft.

Although device described in the document EP 1208963 allows to carry out silk thread on a part of width of tire base Ripple deposition, however it is with some defects.

Firstly, the silk thread of deposition must have a degree of rigidity to be greater than the rotation of tire base when the transmission speed of silk thread The transverse shifting of swing connecting bar is caused when rotary speed.

Secondly, the maximum speed that deposits of the ripple of the maximum frequency of the transverse shifting of swing connecting bar and the device must be by The friction of silk thread and the mechanical restriction of inertia.

Finally, discovery is due to keeping silk thread lateral in the use process of the device described in the document EP 1208963 The distance that mobile device (i.e. guidance roller bearing) and the device (i.e. laying roller bearing) that silk thread is deposited on tire base must separate, silk thread Tend to tighten.In addition, the tension in silk thread may cause plant failure and influence the silk thread deposition quality on tire base, together When future tires manufacture quality be based in part on the deposition quality of the silk thread.

Summary of the invention

Therefore, the purpose of the present invention is to overcome at least one disadvantage of above equipment.

Meanwhile it is a further object to provide the solution of the sedimentary ripple silk thread on cylindrical tire base, institutes Desired silk thread can be deposited beyond length, particularly independently of tire base relative to its theoretical diameter on tire base by stating solution Change in size.

For this purpose, subject of the present invention is a kind of equipment, the equipment deposits on a receiving surface has had corrugated shape Silk thread make the ripple of silk thread cross receiving surface width extend.

The depositing device includes supporting element and deposits soie ondée to the deposition head of receiving surface, which includes the right side Side conveyer and left side conveyer, each conveyer convey multiple element, and the element is for catching silk thread, assigning silk thread ripple Shape and by soie ondée be supplied to receiving surface, the element of each conveyer is along the loop for belonging to each conveyer Alignment, and at least one conveyer is installed into removable relative to another conveyer so that a conveyer is relative to another The movement of one conveyer can change the amplitude of the ripple of the silk thread of deposition.

According to the present invention, depositing device is characterized in that it includes resetting apparatus, and the resetting apparatus tends to make one Conveyer is mobile relative to another conveyer so that the amplitude of the ripple of the silk thread of deposition increases, and depositing device includes passing Equipment is sent, the transmission equipment is used to control the linear velocity of the element for the conveyer that silk thread is sent to deposition head.

The combination of resetting apparatus and transmission equipment make it possible to guarantee soie ondée around cylindrical reception surface (such as Tire base) each circle in deposit desired silk thread and exceed length.Specifically, due to transmission equipment with based on other constant speeds and The constant transmission speed that theoretical size determines transmits silk thread, and resetting apparatus can change the ripple of the silk thread of deposition by moment Amplitude is to compensate variation of the tire base diameter relative to its theoretical value.

Preferably, two conveyers are installed into can rotate around the same adjustment axis.For this purpose, each conveyer peace On warp rail.

It is further preferred that transmission equipment is the form of capstan winch, the capstan winch includes central pulley and centrally disposed pulley Approaching side and two rotation roller bearings for leaving side.

Meanwhile the present invention also proposes the method for the sedimentary ripple silk thread on cylindrical reception surface, the reception table Around center axis thereof rotation driving, which includes using above-mentioned depositing device sedimentary ripple silk on a receiving surface in face Line, while the receiving surface is around center axis thereof rotation driving.

Specific embodiment

As shown in Figure 1, the present invention relates to the equipment 10 for the sedimentary ripple silk thread 12 on receiving surface 14.

In the present invention, silk thread 12 is assigned corrugated shape before depositing to receiving surface 14 in advance.In addition, deposition is set The deposition of silk thread 12 to receiving surface 14 is made the ripple O of silk thread 12 cross the width W14 extension of receiving surface 14 by standby 10.

In target application (i.e. Tire production) of the invention, receiving surface 14 is usually cylindric tire base, and is surrounded Tire base sedimentary ripple silk thread 12 can increase the diameter of the tire base during so-called forming step after making.

Still in the application relevant to Tire production, receiving surface 14 can be tire base or in cylindrical support Manufacture and be intended to be transferred to later the semi-finished product of tire base.

Silk thread 12 is understood to the set of single wire or braiding or twisted silk thread.Silk thread 12 can be (poly- to benzene two by PET Formic acid glycol ester), aramid fiber, nylon, metal, composite material etc. be made.In addition, the set of silk thread 12 or silk thread 12 can be coated with Or insertion rubber compounding object.

According to the present invention, depositing device 10 includes supporting element 16 and deposition head 18, and the deposition head 18 is used to receive table Sedimentary ripple silk thread 12 on face 14.The deposition head 18 includes right side conveyer 20D and left side conveyer 20G, and each transmission Machine 20D, 20G convey multiple element 22, and the element 22 assigns 12 corrugated shape of silk thread and by ripple for catching silk thread 12 Silk thread 12 is supplied to receiving surface 14.

As shown in the top view and side view of the depositing device 10 in Fig. 2 and Fig. 3, the element of each conveyer 20D, 20G 22 are aligned along closed circuit CFD, CFG for belonging to each conveyer.

In order to allow to catch silk thread 12 in a manner of uncinus, the element 22 of each conveyer 20D, 20G are closed towards it The external E of circuit CFD, CFG extend.The external E of loop CFD, CFG are understood to, in the projection of a plane, are located at All parts outside perimeter limited in the plane by loop.

In order to catch silk thread 12, assign 12 corrugated shape of silk thread and the sedimentary ripple silk thread 12 on receiving surface 14, often The element 22 of a conveyer 20D, 20G are configured to move along its loop CFD, CFG.

Advantageously, element 22 is set to move around its loop CFD, CFG so that can not only be moved in translation Flat receiving surface 14 on sedimentary ripple silk thread 12 and also can surround center axis thereof A14 moving in rotation R14 cylinder Sedimentary ripple silk thread 12 on shape receiving surface 14.

As shown in Figure 1, silk thread 12 is transmitted with the rectilinear form extended along delivery axis A12 at deposition head 18.

In order to cause silk thread 12 to be gradually presented corrugated shape, right side conveyer 20D and left side conveyer 20G are facing with each other It is mounted on supporting element 16, so that when each element 22 carries out a whole circle of loop CFD, CFG of its conveyer, one The element 22 of conveyer 20D, 20G row at two positions E1, E2 and along the element 22 of another conveyer 20D, 20G Loop CFD, CFG intersect.

Therefore, as shown in Figures 1 to 3, in the first part P1 for catching silk thread 12 of loop CFD, CFG, one The element 22 of a conveyer 20D, 20G are mobile at the rear of the element 22 of another conveyer 20D, 20G, and in loop CFD, CFG's is used to assign 12 corrugated shape of silk thread and be deposited into the second part P2 of receiving surface 14, a biography Send the element 22 of machine 20D, 20G mobile in the front of the element 22 of another conveyer 20D, 20G.

More specifically, when each part P1, P2 of loop CFD, CFG by conveyer advance, each element 22 are gradually distance from loop CFD, CFG movement of row along the element 22 of another conveyer 20D, 20G, then the element 22 Loop CFD, the CFG for being increasingly towards row along the element 22 of another conveyer 20D, 20G are mobile.Two conveyer 20D, The element 22 of 20G toward and away from gradually move each other allow silk thread 12 gradually forming and allow silk thread 12 shape and No matter it is rigidity or flexibility.

During using depositing device 10, following setting is provided: transmitting silk thread 12 at deposition head 18 and connecing Receive surface 14 in region Z1, Z2 sedimentary ripple silk thread 12, the member of two conveyers 20D, 20G in described region Z1, Z2 Loop CFD, CFG of row are furthest away along part 22.

More specifically, silk thread 12 reaches the arrival region Z1 of the first part P1 of loop CFD, CFG, in the arrival The element 22 of conveyer 20D, 20G are furthest away and back-to-back in the Z1 of region, as shown in Figure 1.Therefore, in arrival region Z1 Later, silk thread 12 is gradually caught by element 22, and the element 22 tends to be moved upward to toward each other at the E1 of first position First crosspoint.

Later, soie ondée 12 is deposited from the deposition region Z2 of the second part P2 of loop CFD, CFG to reception table Face 14, the element 22 of conveyer 20D, 20G are furthest away and face-to-face in the deposition region Z2, as shown in Figure 4.Cause This, when ripple O maximum, silk thread 12 is deposited to receiving surface 14.

Silk thread 12 is received by using identical device (i.e. conveyer 20D, 20G and its element 22) and to assign its corrugated It shape and is deposited to receiving surface 14, the design of depositing device 10 according to the present invention is simplified, therefore its operation is more It is reliable.Advantageously, the gradually forming of silk thread 12 enhances the reliability of depositing device 10.

From the viewpoint of more typically, in the process of the test carried out using prototype laydown equipment 10 according to the present invention In, using conveyer 20D, 20G rather than pendulous device makes element 22 is mobile depositing device 10 according to the present invention is allowed to reach heavy The higher deposition velocity of up to 2.5 meter per seconds of product silk thread 12.

In order to obtain depositing device 10 correct operation and successfully assign 12 corrugated shape of silk thread, conveyer 20D, The movement setting of the element 22 of 20G is synchronous with the movement of the element 22 of another conveyer 20D, 20G setting.More specifically, one The movement setting of the element 22 of a conveyer 20D, 20G is synchronous with the movement of the element 22 of another conveyer 20D, 20G setting, So that then silk thread 12 is alternately caught by the element 22 of conveyer 20D, a 20G by the member of another conveyer 20D, 20G Part 22 is caught.

Meanwhile element 22 also forms silk thread 12 along the synchronization of loop CFD, CFG of conveyer 20D, 20G moved Regular ripple O, when need to accurately control deposition to receiving surface 14 silk thread 12 beyond length when this is extremely important 's.

In order to be easier to implement the synchronization, each conveyer 20D, 20G convey equal number of element 22, such as 12 to 18 A element.

For the same purposes, it is known that the length of loop CFD, CFG are understood to these circuits in the on-state Length, the length of loop CFD, CFG of two conveyers 20D, 20G are identical, and element 22 is closed back along each The length on road is distributed in the same manner.

As described in more detail below, the element 22 of two conveyers 20D, 20G can be made in a manner of mechanically or electrically Mobile synchronization.

In order to avoid must resort to the guidance equipment for helping element 22 to catch silk thread 12 when element 22 intersects, conveyer Each element 22 of 20D, 20G and element 22 leading in loop CFD, CFG of its conveyer 20D, 20G and fall behind Element 22 separates, and right side conveyer 20D and left side conveyer 20G are mounted on supporting element 16 and to hand over when these elements 22 The engagement of element 22 of the element 22 of one conveyer 20D, 20G and another conveyer 20D, 20G when fork and it is preferred that do not contact from And it avoids rubbing.

More specifically, two continuous elements 22 of conveyer 20D, 20G are separated by interval E, when the member of two conveyers When part 22 moves, the interval E allows the element 22 of another conveyer to slide between the two continuous elements 22.

Preferably, all elements 22 of each conveyer pass through along loop CFD, CFG of its conveyer 20D, 20G Aturegularaintervals E separation.Therefore, the period of the ripple O of the silk thread 12 between the different elements 22 of each conveyer 20D, 20G keeps It is constant, and can only change the amplitude of these ripples O to change the silk thread 12 of deposition beyond length, it is as will be explained hereinafter.

Certainly, due to the engagement of element 22, the synchronizing moving of the element 22 of two conveyers 20D, 20G is necessary, no Then element 22 can collide.

According to the present invention, profile of at least one portion P1, P2 of each loop CFD, CFG along row circular shape. However, it is preferred that the second part P2 of loop CFD, CFG in the Z2 of deposition region along the profile of row circular shape, described The element 22 of conveyer 20D, 20G are for sedimentary ripple silk thread 12 on a receiving surface in the Z2 of deposition region.By heavy in silk thread Circular contour is provided in product region Z2, two loops CFD, CFG allow sedimentary ripple silk thread 12 and soie ondée 12 is not It can be slided on cylindrical reception surface 14 (such as tire base).

It is further preferred that each conveyer 20D, 20G are the form for taking turns 24D, 24G, described wheel 24D, 24G are mounted on supporting element On 16 and around rotation RD, RG driving of center axis thereof AD, AG.It is, for example, chain conveyor compared to conveyer 20D, 20G The design of the form of (element 22 is fixed to the chain conveyor), the circular shape of conveyer 20D, 20G simplify design because This reduces the manufacturing cost of deposition head 18.

Certainly, for the appropriate operation of depositing device 10 and due to the engagement of element 22, two wheel 24D, 24G with circle RD, RG driving are rotated on the direction of rotation R14 of column receiving surface 14 opposite direction.

Due to the preferred circular shape of conveyer 20D, 20G, loop CFD, CFG of these conveyers be it is round simultaneously And element 22 is distributed around the circumference of these loops CFD, CFG with aturegularaintervals E.

Again less preferably, round sealed circuit CFD, CFG of two conveyers 20D, 20G have same diameter D20.

Further, central axis AD, AG of two wheels 24D, 24G are located in the same reference planes PR, and two Central axis AD, AG and two round sealed circuit CFD, CFG of wheel 24D, 24G are in reference planes PR at the PI of crosspoint With intersecting angle AI intersection, so as to limit the amplitude of the ripple O deposited to the soie ondée 12 of receiving surface 14.Therefore, When angle A I is zero, central axis AD, AG of two wheels 24D, 24G are consistent and element 22 cannot catch silk thread 12 or assign Its corrugated shape.In addition, intersecting angle AI increased more, the member of two wheels 24D, 24G in the deposition region Z2 of silk thread 12 The distance between part 22 D increased more, as a result, the amplitude of the ripple O of the silk thread 12 of deposition increases.

More specifically, round sealed circuit CFD, CFG is being located at two of the two sides reference planes PR along reference straight line DR At point PT1, PT2 intersect, it is described with reference to straight line DR perpendicular to reference planes PR and from the central axis in reference planes PR The crosspoint PI certain distance of AG, AD, two crosspoints PT1, PT2 are also equidistant with the crosspoint PI of central axis AD, AG.Cause This, two points PT1, PT2 are accurately defined two positions E1, E2 that the element 22 of two conveyers intersects.

In order to allow the element 22 of conveyer 20D, a 20G and the element 22 of another conveyer 20D, 20G to engage, and And known wheel 24D, 24G include cylindrical body 26, each element 22 of wheel 24D, 24G are mounted on the end of arm 28, the arm 28 extend on the axial direction DA that at least one is parallel to central axis AD, AG of the wheel 24D, 24G from cylindrical body 26.

In the more advanced variant form of Fig. 5 and conveyer 20D, 20G shown in fig. 6, each arm 28 also perpendicular to It takes turns and extends on the radial direction DR of central axis AD, AG of 24D, 24G from cylindrical body 26.Therefore, because each element 22 It is radially offset from relative to its cylindrical body 26 for taking turns 24D, 24G, can include having in the areas adjacent of deposition silk thread 12 Sedimentary ripple silk thread 12 on the receiving surface 14 (such as tire base) of excessive thickness or part outstanding.

Again in the further variant form of conveyer 20D, 20G shown in Figures 5 and 6, arm 28 is detachable Ground is mounted on the independent component on the cylindrical body 26 of wheel 24D, 24G.It therefore, can be simply by changing arm 28 to change Dependent element 22 being axially displaced from and/or being radially offset from, therefore can be avoided integral demounting wheel 24D, 24G, especially avoids from branch The disassembly of support member 16 takes turns 24D, 24G and avoids that wheel 24D, 24G is made to rotate driving device disengaging.

In first embodiment of the invention, such as by means of universal joint or the connector of constant-velocity joint type 47 Mechanically realize the synchronization of wheel 24D, 24G, the connector 47 is visible in Fig. 4.

However, since such mechanical fastener is prone to wear and presents increasing clearance, shown in Fig. 6 In two embodiments, more reliably realizes synchronize in an automated manner.For this purpose, each wheel 24D, 24G is enclosed by following device It rotates and drives around center axis thereof AD, AG: the motor 25D, 25G of its own, the rotation speed of the two motors can be made synchronous Electronic device, and pulley/belt component 27D, 27G of connection each motor 25D, 25G and its wheel.

Preferably, each element 22 is pin 23, and the pin 23 is along the central axis for taking turns 24D, 24G perpendicular to it The longitudinal axis A23 of AD, AG extend.

Therefore, in order to shape and deposit the silk thread 12 with a degree of viscosity, each pin 23 can be surrounded Its longitudinal axis A23 rotation, or alternatively each pin 23 is equipped with guidance roll shaft 30 as shown in Figures 1 to 4, it is described to draw Guide roller axis 30 is mounted to rotate around its longitudinal axis A23.

In order to improve deposition quality of the soie ondée 12 on receiving surface 14 and avoid the receiving surface 14 by pin 23 labels, each pin 23 are mounted to along the first expanded position its longitudinal axis A23 shown in Fig. 7 and such as Fig. 8 Shown in translation T23 is mobile between the second retracted position, pin 23 catches silk thread 12 to assign under first expanded position Its corrugated shape is given, pin 23 discharges silk thread 12 to be deposited to receiving surface 14, instead under second retracted position ?.

In order to which the installation can translate the mobile purpose of T23, each pin 23 is installed into the arm 28 by the pin 23 It is slided in the casing 32 of carrying.

In Fig. 7 and the non-limiting variant form shown in Fig. 8 for installing pin 23 on arm 28, pass through rolling bearing 36 Casing 32 is installed on ring 34 and realizes that pin 23 surrounds the rotation R23 of its longitudinal axis A23, such as force-fitting of ring 34 or viscosity knot It is bonded in the hole 38 being arranged in the arm 28 of the pin 23.

In the use process of depositing device 10, more accurately when pin 23 and receiving surface 14 contact, the pin 23 Pushed towards its retracted position and discharge silk thread 12 to making silk thread 12 be adhered to receiving surface 14, the receiving surface 14 or The offer of silk thread 12 carries out depositing required a degree of viscosity.Advantageously, in the contraction process of pin 23,32 direction of casing Receiving surface 14 squeezes silk thread 12.

Furthermore resetting apparatus 40 is set, the resetting apparatus 40 makes each pin 23 be reset to its expansion from its retracted position Position.Therefore, during new one circle of loop CFD, CFG, each pin 23 can be re-used for catching silk thread 12 And assign its corrugated shape.

In the non-limiting variant form shown in Fig. 7 and 8, in order to install pin 23 on arm 28, it is known that pin 23 is The form of longitudinal ontology 43 with lower end 44, these resetting apparatuses 40 are to be fixed to arm 28 and against 23 lower end 44 of pin The form of leaf spring 42.

As described above, the intersecting angle AI of central axis AD, AG of two wheels 24D, 24G in reference planes PR makes it possible to The amplitude of the ripple O of silk thread 12 is enough limited, therefore length can be exceeded by the silk thread 12 of these ripples O control deposition.

In addition, each wheel 24D, 24G are mounted on respective in first embodiment of the invention shown in Fig. 1 to 4 On half supporting element 16D, 16G, by be positioned relative to each other half supporting element 16D, 16G and by the deposition of soie ondée 12 to connecing It is held in place half supporting element 16D, 16G to letter by means of any suitable device during the deposition cycle on receipts surface 14 Singly adjust intersecting angle AI.

Furthermore it is advantageous that changing the amplitude of the ripple O of silk thread 12 during the deposition process, such as the silk thread to make deposition The variation of 12 diameter for adapting to cylindric tire base in real time beyond length.

In addition, depositing device 10 includes for adjusting the angle of the crossing in of the invention second embodiment shown in Fig. 6 Spend the automation equipment 46 of AI.

More specifically, each wheel 24D, 24G are mounted on mounting plate 48D, 48G, each mounting plate, which is directed into, to be bent It is rotated on track 50D, 50G and each mounting plate 48D, 48G is configured to motor 52D, 52G by its own via tooth Item/pinion assemblies 54D, 54G rotate on its warp rail 50D, 50G.

Preferably, two mounting plates 48D, 48G and two wheels 24D, 24G surround the same tune perpendicular to reference planes PR Nodal axisn line AR rotation driving.

More specifically, in order to make silk thread 12 be located at it is ideal enter in axis A12, adjustment axis AR the two circuits CFD, The first part P1's of CFG enters the circle that two wheels 24D, 24G are substantially tangential in region Z1 (i.e. the rear of deposition head 18) Shape closed circuit CFD, CFG.

Finally, depositing device 10 further includes making deposition head 18 around orientation in second embodiment of the invention The device 56 of axis AO orientation, the orientated axis AO are separated perpendicular to reference planes PR but with adjustment axis AR.Preferably, Orientated axis AO is located at the front of deposition head 18 and in the deposition region Z2 of soie ondée 12 and along row circular shape The second part P2 tangent of loop CFD, CFG of profile.Therefore, when receiving surface 14 is cylindric, orientated axis AO Also with 14 tangent of receiving surface.Preferably, deposition head 18 is driven to surround the rotation of its orientated axis AO by means of motor 58 R18, and rotation R18 makes it possible in arch or with sedimentary ripple silk thread 12 on the receiving surface 14 for protruding shape.

More generally, and again for during the deposition process change silk thread 12 ripple O amplitude, the present invention propose to Few conveyer 20D, a 20G are installed into can be mobile relative to another conveyer so that the conveyer is relative to another The movement of conveyer can change the amplitude of the ripple O of the silk thread 12 of deposition.

For example, the single 24D that takes turns is configured to around adjustment axis in third embodiment of the invention shown in Fig. 9 Line AR rotates R24, and the ideal that the adjustment axis AR preferably corresponds to silk thread 12 enters axis A12.For this purpose, wheel 24D is installed On supporting element 60, the supporting element 60 is directed on warp rail 62 to be rotated around adjustment axis AR.

Again in the third embodiment, depositing device 10 includes resetting apparatus 64, and the resetting apparatus 64 is inclined to 24D is mobile relative to another wheel 24G so that the amplitude of ripple O of the silk thread 12 of deposition increases in making to take turns, these resetting apparatuses 64 are associated with transmission equipment 66, as shown in figure 11, enable control over by silk thread 12 be sent to wheel 24D, 24G pin 23 (or Person more generally, is sent to the element 22 of conveyer 20D, 20G of deposition head 18) linear velocity V12.

More specifically, resetting apparatus 64 acts on the supporting element 60 of wheel 24D and works as in the third embodiment Squeeze operation when tending to increase the amplitude of the ripple O of silk thread 12.

In the 4th embodiment shown in Fig. 10, depositing device 10 includes two wheels 24D, 24G, described two wheels 24D, 24G are mounted to rotate R24D, R24G around adjustment axis AR, and the adjustment axis AR preferably corresponds to silk thread 12 The ideal resetting apparatus 70 that enters axis A12, and taken turns between 24D, 24G between two tend to make a wheel relative to another One wheel is mobile so that the amplitude of the ripple O of the silk thread 12 of deposition increases.

As described above, these resetting apparatuses 70 are associated with transmission equipment 66, as shown in figure 11, enable control over silk thread 12 are sent to the pin 23 (or more generally, being sent to the element 22 of conveyer 20D, 20G of deposition head 18) of wheel 24D, 24G Linear velocity V12.

More specifically, each wheel 24D, 24G are mounted on supporting element 72D, 72G, described in the 4th embodiment Supporting element 72D, 72G are directed on warp rail 74D, 74G to be rotated around adjustment axis AR.In addition, resetting apparatus 70 is situated between Between the two supporting elements 72D, 72G, and its tensioning operation when it tends to increase the amplitude of the ripple O of silk thread 12.

In the third of depositing device 10 or the 4th embodiment, transmission equipment 66 is capstan winch form, the capstan winch Approaching side including central pulley 76 and centrally disposed pulley 76 and two rotation roller bearings 78E, 78S for leaving side.

The two sides of two centrally disposed pulleys 76 of rotation roller bearing 78E, 78S are to squeeze silk thread towards central pulley 76 12.In addition, the rotation speed V76 of central pulley 76 makes it possible to directly control the transmission linear velocity of the silk thread 12 at deposition head 18 V12.Further, it is also possible to which belt (not shown) is arranged, the belt squeezes silk thread 12 towards central pulley 76 and avoids silk thread 12 slide on central pulley 76.

The combination of resetting apparatus 64,70 and transmission equipment 66 makes it possible to guarantee in soie ondée 12 around cylindrical reception The desired silk thread 12 for exceeding length is deposited in every circle on surface 14 (such as tire base), particularly no matter the receiving surface 14 surrounds How is the diameter D14 of center axis thereof A14.

Specifically, it interacts via the tensioning of silk thread 12 and with transmission equipment 66, when silk thread 12 is in 66 He of transmission equipment The amplitude of the ripple O for the silk thread 12 that resetting apparatus 64, the increase of 70 moments deposit when relaxation between deposition head 18, when deposition head 18 connects When receiving the speed of silk thread 12 than by the speed of the deposition of silk thread 12 to receiving surface 14 faster, such as due to the diameter of receiving surface 14 D14 reduces relative to the previous circle silk thread 12 around receiving surface 14, and the tensioning of silk thread 12 reduces.

Again, it interacts via the tensioning of silk thread 12 and with transmission equipment 66, when silk thread 12 is in 66 He of transmission equipment The amplitude of the ripple O for the silk thread 12 that resetting apparatus 64, the reduction of 70 moments deposit when tightening between deposition head 18, when deposition head 18 is heavy When the speed of product soie ondée 12 is than receiving the speed of soie ondée 12 faster, such as due to the diameter D14 phase of receiving surface 14 Previous circle silk thread 12 around receiving surface 14 is increased, the tensioning of silk thread 12 increases.

More specifically, tensioning confrontation is filled by resetting when silk thread 12 is tightened between transmission equipment 66 and deposition head 18 The power of 64,70 applications is set, therefore intersecting angle AI reduces between central axis AD, AG of two wheels 24D, 24G, causes silk thread 12 Ripple O amplitude reduce.

In addition, tensioning no longer confrontation is filled by resetting when the relaxation between transmission equipment 66 and deposition head 18 of silk thread 12 The power of 64,70 applications is set, therefore intersecting angle AI increases between central axis AD, AG of two wheels 24D, 24G, causes silk thread 12 Ripple O amplitude increase.

The invention further relates to the method for the sedimentary ripple silk thread 12 on cylindrical reception surface 14, the cylindrical reception table Face 14 is around center axis thereof A14 rotation R14 driving.According to the present invention, which includes using third or the 4th Depositing device 10 in the embodiment sedimentary ripple silk thread 12 on receiving surface 14, while the receiving surface 14 surrounds its center Axis A14 rotates R14 driving.

During the deposition method, the rotation R14 of receiving surface 14 is mobile synchronous so that working as element with element 22 The linear velocity V22 of element 22 is equal to the tangential velocity that receiving surface 14 surrounds center axis thereof A14 when 22 contact receiving surface 14 VT14.Therefore this avoids following situation: element 22 relative to surface 14 by sliding during sedimentary ripple silk thread 12 And damage receiving surface 14.

Preferably, and independently of deboost phase and boost phase, the element 22 during sedimentary ripple silk thread 12 The tangential velocity VT14 of linear velocity V22 and receiving surface 14 is kept constant.

It is thus known that receiving surface 14 carries out time T used in a full circle around center axis thereof A14 and is considered as Cross silk thread 12 to be deposited during each circle of the silk thread 12 of the width W14 of receiving surface 14 beyond length S, according to Deposition method of the invention proposes that each circle of the silk thread 12 for being considered as crossing the width W14 of receiving surface 14 is depositing To transmit linear velocity V12 transmission silk thread 12 at first 18, the transmission linear velocity V12 is constant and to be deposited equal to during the circle Silk thread 12 beyond length S divided by receiving surface 14 carry out the ratio that time T is obtained used in the circle, i.e. V12=S/T, Wherein the unit of V12 is meter per second, and the unit of S is that the unit of rice and T are the second.

By carrying out in this way, each circle of the silk thread 12 for being considered as crossing the width W14 of receiving surface 14, It ensure that depositing the desired silk thread for exceeding length S around receiving surface 14, resetting apparatus 64,70 automatically adjusts ripple O's Amplitude is to adapt to the ratio between the transmission linear velocity V12 of silk thread 12 and the tangential velocity VT14 of receiving surface 14.

Further, since the amplitude of ripple O can be automatically adjusted to adapt to the transmission linear velocity V12 of silk thread 12 and receiving surface Ratio between 14 tangential velocity VT14, resetting apparatus 64,70 can also be decreased or increased by moment the amplitude of ripple O from And the reception table as caused by the scrambling of the shape of receiving surface 14 or the diameter D14 variation of receiving surface 14 is compensated automatically The positive variation or negative variation of the tangential velocity VT14 in face 14.

It is advantageously discovered that, when using above-described deposition method, is equipped with resetting apparatus 64,70 and transmission equipment 66 Depositing device 10 can deposit diameter of the desired silk thread 12 beyond length S without knowing tire base, this is in Tire production Aspect is particularly advantageous.

Particularly, in target application of the invention, deposition method and depositing device 10 are used for the sedimentary ripple on tire base Silk thread 12.

Advantageously, the ripple O of the silk thread 12 of deposition allows the subsequent increase of tire base diameter.

Thus, for example being used to prepare the soie ondée 12 of so-called zero degree enhancing casing ply can be deposited with " flat " state To tire base, i.e., before the tire base is subjected to forming step to realize cylindrical shape or annulus shape.

Certainly, soie ondée 12 be also used to prepare tire base other reinforcements or other casing plies, and can also calculate The ripple O of silk thread 12 and the other increases for allowing tire base diameter, for example, the tire base undergone in its sulfurizing mould it is additional at Shape.

In the case where preparing so-called zero degree enhancing casing ply, a few soie ondées 12 are deposited around tire base.

It is of course also possible to around tire base deposit a few soie ondées 12 to prepare other types of tire texture or its The reinforcement of its type.

Since the final shape of tire base is annulus shape rather than cylindric, the tire shoulder for needing to reduce around future tires is heavy The width of the ripple O of silk thread 12 in the central part of the amplitude of the ripple O of long-pending silk thread 12 and the crown for increasing future tires Degree.

In addition, the deposition method proposes, the amplitude of the ripple O of the silk thread 12 of deposition is from being considered as crossing the width of tire base Circle silk thread to an another circle silk thread of W14 changes.For this purpose, in tire base around the process of the new circle of each of center axis thereof A14 In be enough to change intersecting angle AI between central axis AD, AG of two wheels 24D, 24G.
