Description

    The present invention relates to a belt-like rubber winding method and apparatus for supplying a belt-like rubber member to the outer surface of a wound body and winding it spirally.

As a conventional method and apparatus for winding a belt-shaped rubber member, for example, the one described in Patent Document 1 below is known.
JP 2004-216603 A

  In this product, a hard core having the same outer shape as the inner surface of the product tire is rotated, a belt-like rubber member is supplied to the outer side of the hard core and spirally wound to form an inner liner, and then a rubber bead wire is spirally wound. To form an inner bead layer. Next, after knitting a carcass layer on the outer side of the inner liner and inner bead layer, the outer bead layer is molded in the same manner as the inner bead layer, and then the side wall rubber member is wound in a spiral shape to form a sidewall, A belt layer is knitted, and then a tread rubber is formed by spirally winding a belt-shaped rubber member to form a green tire.

  Here, for example, in the formation of the tread rubber as described above, the hard core is rotated around the axis while the extruder is moved in a horizontal plane along the outer surface of the hard core while extruding the belt-shaped rubber member from the extruder. Thus, the belt-like rubber member is supplied to the hard core one after another, and is wound and laminated on the outer surface in a spiral manner. At this time, the outer side in the radial direction of the hard core around which the belt-like rubber member is wound is formed. Since the side surface is curved in a substantially arc shape, the extruder is rotated around the vertical axis as the winding position changes, and the belt-like rubber member is supplied so as to be substantially perpendicular to the inclination of the hard core at the winding position. Yes.

  As a supply method / apparatus for supplying a belt-shaped rubber member to such an extruder, the present applicant has disclosed in Japanese Patent Application No. 2004-272714 a storage case storing the belt-shaped rubber member, and the storage case and the extruder. And a conveyor belt installed between them, and a belt-like rubber member is drawn out from the storage case by the conveyor and sent out to the extruder.

  In recent years, in order to improve snow and snow performance and wet performance, pneumatic tires constructed by laminating a plurality of different types of rubber with different treads have been proposed. To manufacture such tire treads, A plurality of extruders that can move synchronously in the axial direction of the wound body (tire intermediate body) are set apart from each other in the axial direction of the wound body, and between the storage case and the extruder, It can be considered that a plurality of conveying conveyors for feeding out different kinds of drawn-out rubber members to a corresponding extruder are left stationary.

  When the belt-like rubber member is wound around the wound body by such a thing, the belt-shaped rubber member of a predetermined type is placed on the covered body by an extruder located at the winding position immediately after the wound body. The belt-shaped rubber member is supplied to the wound body, and is drawn out of the storage case by the transport conveyor corresponding to the extruder at the winding position, and then fed into the extruder.

  When a predetermined type of belt-shaped rubber member is wound around the wound body in this way, all the extruders are synchronously moved in the axial direction, and the standby position separated from the winding position in the axial direction of the wound body. The extruder that has been waiting in step 1 is moved to the winding position, and the extruder that has been performing the winding operation is moved from the winding position to the standby position. After that, a belt-shaped rubber member of a type different from the predetermined type is pulled out from the storage case by a conveyor corresponding to the extruder that has moved to the winding position, and supplied to the extruder at the winding position to be wound around the wound body. To do.

    However, in the winding method and apparatus for the belt-shaped rubber member as described above, the conveyor conveyer corresponding to each extruder is left stationary even though the extruder moves in the axial direction of the wound body. Therefore, when the extruder is moved, the relative positional relationship between the corresponding extruder and the conveyor is changed. As a result, the belt-shaped rubber member that is continuously stretched between the corresponding extruder and the conveyor is swung every time the extruder moves between the winding position and the standby position, and the corresponding extrusion As a result, the distance between the machine and the conveyor is changed. As a result, the belt-like rubber member is bent and twisted during winding, and there is a problem that entanglement or breakage may occur.

  An object of the present invention is to provide a method and an apparatus for supplying a belt-like rubber member that can effectively reduce bending and twisting generated in the belt-like rubber member by synchronously moving the corresponding winding means and delivery means. To do.

    The first purpose is to pull out a predetermined type of belt-like rubber member from a storage means that temporarily stores different types of belt-like rubber members by a feeding means installed behind the winding means, and to wind the position. The belt-like rubber member is supplied to the outer surface of the rotating wound body by moving the winding means along the outer surface of the wound body while being fed to the winding means of the spiral. A step of waiting the remaining winding means at a standby position separated from the winding position in the axial direction of the wound body, and an axis of the wound body together with the plurality of winding means By moving the winding means located in the winding position to the standby position, moving the winding means located in the standby position to the winding position, respectively, and installing the winding means behind the winding means. Synchronized transfer of the delivered means with the winding means And a step of spirally winding a belt-like rubber member of a type different from the predetermined type fed from the storage means and the sending means by the winding means moved to the winding position around the outer surface of the wound body; Can be achieved by a method of supplying a belt-shaped rubber member provided with

  Second, a movable base that is movable in the axial direction of a rotatable wound body around which the belt-shaped rubber member is wound on the outer surface, and supported by the movable table, along the outer surface of the wound body A plurality of winding means that are movable and can be spirally wound by supplying a belt-like rubber member to the outer surface of the wound body, the winding means being spaced apart in the axial direction of the wound body; By moving the moving table, one of the winding means is moved to the winding position where the belt-like rubber member is wound around the wound body, and the remaining winding means are moved to the standby position separated from the winding position in the axial direction. Moving means that can be moved, storage means for temporarily storing different types of belt-shaped rubber members, and installed behind the winding means between the winding means and the storage means, and pulls the belt-shaped rubber members from the storage means Can be sent to the winding means at the winding position and synchronized with the winding means. The feeder of the belt-shaped rubber member and a possible delivery means, can be achieved.

  When different types of belt-shaped rubber members are wound around the wound body, the winding means at the winding position is moved to the standby position and the winding means at the standby position is moved to the winding position by moving the movable table. However, at this time, the corresponding winding means and the sending means are moved synchronously, and in detail, the respective sending means are arranged so that the corresponding winding means are moved so that the relative positional relationship in the axial direction does not change. Since it is always located behind the winding means, even if the winding means moves as described above, the belt-like rubber member always stretched between the winding means and the sending means is swung, There is no change in the relative distance between the corresponding winding means and delivery means, and as a result, bending and twisting that occur in the belt-like rubber member during winding are reduced. This prevents a situation where the belt-like rubber member is tangled or cut off in the middle.

  According to the third aspect of the present invention, the distance between the corresponding winding means and the feeding means is shortened, and bending and twisting generated in the belt-like rubber member stretched between the winding means and the feeding means. Is further reduced. At this time, there is a long belt-like rubber member stretched in the air under a constant tension between the corresponding delivery means and the guide means. However, since the guide means moves synchronously with the corresponding delivery means, The belt-like rubber member between the feeding means and the guide means that does not swing and the distance between them does not change, and as a result, the bending and twisting that occurs in the belt-like rubber member is reduced.

Furthermore, as described in claims 4 and 5, a storage case that can store the belt-like rubber member or a roll around which the belt-like rubber member is wound can be used as the storage means.
According to the sixth aspect of the present invention, there is no need for a separate mechanism for synchronously moving the sending means to the corresponding winding means, thereby simplifying the structure and reducing the manufacturing cost.

In FIGS. 1, 2, and 3, reference numeral 11 denotes a horizontal main shaft that is driven and rotated by a drive unit 12, and the main shaft 11 is provided with a molding drum (not shown) for forming a green tire. Reference numeral 13 denotes a tire intermediate body as a wound body supported by the molding drum. The tire intermediate body 13 is formed by attaching tire constituent members around the molding drum one after another and deforming it into a substantially toroidal shape. Has been.

A motor 30 is attached to the base 16 and an output shaft thereof is connected to the screw shaft 28. The motor 30 applies a rotational force to the screw shaft 28.

  The moving base body 18 is guided by the guide rail 17 by receiving a driving force from the screw shaft 22 when the motor 24 is operated, and the moving base body 19 is operated from the screw shaft 28 when the motor 30 is operated. While being guided by the guide rail 17 by receiving the driving force, each moves in the left-right direction, in other words, in the axial direction of the rotatable tire intermediate 13. At this time, since the screw shafts 22 and 28 are simultaneously rotated by an equal amount, the movable base bodies 18 and 19 are integrally moved synchronously by an equal distance in the same direction.

  A pair of guide rails 34 and 35 extending in the front-rear direction are laid on the upper surfaces of the movable table main bodies 18 and 19, respectively, and above the movable table main bodies 18 and 19, a lower side parallel to the movable table main bodies 18 and 19 is provided. Tables 36 and 37 are installed, respectively. Reference numerals 38 and 39 denote a plurality of slide bearings fixed to the lower surfaces of the lower tables 36 and 37, respectively. The slide bearings 38 and 39 are slidably engaged with the guide rails 34 and 35, respectively.

  The lower tables 36 and 37 can move in the front-rear direction while being guided by the guide rails 34 and 35 by receiving a driving force from a driving mechanism (not shown) such as a screw mechanism. A pair of arcuate guide rails 43 and 44 having the same curvature center as the center of curvature of the outer surface of the tire intermediate 13 are laid on the upper surfaces of the lower tables 36 and 37, respectively. The upper tables 45 and 46 parallel to the lower tables 36 and 37 are respectively installed above the upper tables.

  Reference numerals 47 and 48 denote a plurality of slide bearings fixed to the lower surfaces of the upper tables 45 and 46, respectively. The slide bearings 47 and 48 are slidably engaged with the guide rails 43 and 44, respectively. The upper tables 45 and 46 are rotated while being guided by the guide rails 43 and 44 and moved along the outer surface of the tire intermediate 13 by receiving driving force from a driving mechanism (not shown) such as a turning mechanism. To do.

  Reference numerals 52 and 53 denote support boxes fixed to the upper surfaces of the upper tables 45 and 46, respectively. The support boxes 52 and 53 are respectively attached with extruders 54 and 55 extending in the vertical direction. 56 and 57 are vertically extending screws accommodated in the extruders 54 and 55, respectively. These screws 56 and 57 receive a driving force from a rotating mechanism (not shown) built in the support boxes 52 and 53. Each can rotate.

  When these screws 56 and 57 are rotating, different types of belt-like rubber members 63 and 64 are placed in the extruders 54 and 55 through hoppers 61 and 62 provided at the lower ends of the extruders 54 and 55, respectively. When supplied, the belt-like rubber members 63, 64 are transferred upward while being heated by screws 56, 57, and then from the extrusion heads 65, 66 provided at the upper ends of the extruders 54, 55. Extruded as narrow band rubber members 67 and 68, respectively.

  70 and 71 are brackets which are fixed to the extruders 54 and 55 directly below the hoppers 61 and 62 and extend rearward.The upper surfaces of the rear end portions of the brackets 70 and 71 are a pair of guide rollers 72 extending in the vertical direction. Each 73 is rotatably supported. The guide rollers 72 and 73 rotate while pinching the rubber band members 63 and 64 from both sides, thereby guiding the rubber band members 63 and 64 to the hoppers 61 and 62 of the extruders 54 and 55, respectively. 77 and 78 are a pair of applicator rolls rotatably supported by the extruders 54 and 55 immediately before the extrusion heads 65 and 66. These applicator rolls 77 and 78 are the extrusion heads of the extruders 54 and 55. The belt-like rubber members 67 and 68 pushed out from 65 and 66 can be pressed against the outer surface of the tire intermediate 13 to be pressure-bonded respectively.

  The above-described extruder 54 and applicator roll 77 as a whole constitute the winding means 85 supported on the movable table main body 18 via the upper tables 36 and 45 and the support box 52, and the extruder 55, As a whole, the applicator roll 78 is supported by the movable table body 19 via the lower and upper tables 37 and 46 and the support box 53, and is arranged so as to be separated from the winding means 85 in the axial direction of the tire intermediate body 13. The winding means 86 is configured.

  Here, the plurality of (two) winding means 85 and 86 can move along the outer surface of the tire intermediate 13 by the operation of the drive mechanism described above. Is moved to the tire intermediate 13 from the winding means 85 and 86 by supplying the belt-like rubber members 67 and 68 to the outer surface of the tire intermediate 13 in a spiral manner. Can be wound.

  When the tire intermediate 13 rotates around the axis together with the forming drum, for example, at the winding position K where the belt-shaped rubber member is wound around the tire intermediate 13, that is, around the tire intermediate 13. When the turning means 85 is positioned, the winding means 85 receives the driving force from the drive mechanism and turns along the outer surface of the tire intermediate body 13 while turning in the horizontal plane around the center of curvature together with the upper tables 45 and 46. The belt-like rubber member 67 extruded from the extruder 54 is supplied to the outer surface of the tire intermediate body 13 and spirally wound.

  At this time, the remaining winding means 86 is supported by the movable base body 19 that is separated by a predetermined distance on the left side in the axial direction of the tire intermediate body 13 from the movable base body 18 that supports the winding means 85. The winding means 86 stands by at a left standby position L separated from the winding position K to the left in the axial direction. In this embodiment, the left standby position L is not directly next to the winding position K, but is a position where the upper tables 37 and 46 and the winding means 86 are moved slightly rearward by the drive mechanism.

  Next, the motors 24 and 30 are operated synchronously to move the movable base bodies 18 and 19 synchronously integrally to the right, and the upper tables 36 and 45 and the winding means 85 are slightly moved rearward by the drive mechanism. On the other hand, when the lower and upper tables 37 and 46 and the winding means 86 are moved slightly forward, the winding means 85 moves to the right standby position R separated from the winding position K to the right in the axial direction, The winding means 86 moves from the left standby position L to the winding position K.

  Thereafter, the winding means 86 receives the driving force from the driving mechanism and swivels in the horizontal plane, while the belt-like rubber member 68 pushed out of the extruder 55 is rotated outside the tire intermediate body 13 rotating around the axis. It is supplied to the surface and wound spirally. In this way, a plurality of, in this case two, winding means 85 and winding means 86 separated by a predetermined distance in the axial direction of the tire intermediate body 13 are configured so that the moving table 82 constituted by the moving table main bodies 18 and 19 is in the middle of the tire. By moving in the axial direction of the body 13, it is possible to move between the winding position K and the right standby position R and between the left standby position L and the winding position K, respectively.

  The guide rail 17, the screw shafts 22 and 28, and the motors 24 and 30 described above are moved as a whole by moving the moving base 82 in the axial direction of the tire intermediate body 13, thereby enabling any one of the winding means 85 and 86 to move. In the winding position K where the belt-like rubber members 67, 68 are wound around the tire intermediate 13, the remaining winding means 85, 86 are moved to the right and left standby positions R, L separated from the winding position K in the axial direction. A moving means 91 that can be moved is configured.

  Reference numerals 95 and 96 denote storage cases that are installed behind the winding means 85 and 86, respectively, and serve as storage means for temporarily storing different types of belt-like rubber members 63 and 64 that are open at the top. A large number of belt-like rubber members 63 and 64 are stored and stored in a zigzag manner. Reference numerals 100 and 101 denote horizontal transfer conveyors as delivery means installed immediately after the respective winding means 85 and 86 between the winding means 85 and 86 and the storage cases 95 and 96. Extends in the front-rear direction, and is attached to the movable table 82, that is, the movable table main bodies 18 and 19 via the lower and upper tables 36 and 45 and the lower and upper tables 37 and 46, respectively.

  As a result, the conveyors 100 and 101 move synchronously with the corresponding winding means 85 and 86, and the corresponding winding means 85 and 86 move in detail so that the relative positional relationship in the axial direction does not change. However, it always follows and moves so as to be positioned behind the winding means 85 and 86, respectively. The conveyors 100 and 101 operate when the corresponding winding means 85 and 86 are located at the winding position K, and draw the belt-like rubber members 63 and 64 from the storage cases 95 and 96. Can be sent to 85, 86.

  Here, since the transfer conveyors 100 and 101 are attached to the moving table 82 immediately after the winding means 85 and 86 as described above, the relative relationship between the transfer conveyors 100 and 101 and the winding means 85 and 86 is relatively small. The distance M is shortened, and even if the winding means 85 and 86 move to change the positions K, L and R, the relative distance M does not change. As a result, the winding means 85 and 86 are conveyed. Bending and twisting generated in the belt-like rubber members 63 and 64 stretched between the conveyors 100 and 101 are further reduced. Furthermore, since the transfer conveyors 100 and 101 are attached to the moving table 82, a separate mechanism for moving the transfer conveyors 100 and 101 to the corresponding winding means 85 and 86 synchronously becomes unnecessary, which makes the structure simpler and less expensive to manufacture. Can be made inexpensive.

   105 and 106 are a pair of support posts installed in parallel behind the conveyors 100 and 101 and immediately before the storage cases 95 and 96. The support posts 105 and 106 include guide rods 107 and 108 extending in the left-right direction. Both end portions of the screw shafts 109 and 110 extending parallel to the guide rods 107 and 108 are rotatably supported. Reference numerals 114 and 115 are guide means slidably engaged with the guide rods 107 and 108, respectively, and the screw shafts 109 and 110 are screwed in. The guide means 114 and 115 are transport conveyors 100 and 101, respectively. The belt-like rubber members 63 and 64 drawn out from the storage cases 95 and 96 are guided behind the storage cases 95 and 96.

  Here, the belt-like rubber members 63 and 64 stretched between the transport conveyors 100 and 101 and the guide means 114 and 115 in the air are given a constant tension by the guide means 114 and 115, but the storage case Since no resistance is applied to the belt-like rubber members 63 and 64 that are being drawn out from 95 and 96 to the guide means 114 and 115, almost no internal tension is generated.

   116 and 117 are motors attached to the support posts 105 and 106, and the output shafts are connected to the screw shafts 109 and 110. These motors 116 and 117 can apply a rotational force to the screw shafts 109 and 110, respectively. . The guide means 114, 115 is operated in the left-right direction while being guided by the guide rods 107, 108 by rotating the screw shafts 109, 110 when the motors 116, 117 are operated, in other words, the axis of the tire intermediate body 13. Move in the direction.

  At this time, since the operation of the motors 116 and 117 is controlled, the guide means 114 and 115 are synchronously moved at the same speed in the same direction simultaneously with the corresponding transport conveyors 100 and 101, and the guide means 114 and 115 and the transport conveyor The relative positional relationship with 100 and 101 does not change. The screw shafts 109 and 110 and the motors 116 and 117 described above constitute a guide drive mechanism 120 that moves the guide means 114 and 115 in synchronization with the corresponding transfer conveyors 100 and 101 as a whole.

  Thus, when the conveyors 100 and 101 are installed immediately after the winding means 85 and 86 and the guide means 114 and 115 are installed immediately before the storage cases 95 and 96, the corresponding conveyors 100, 101 and guide means are installed. Between 114 and 115, there are long belt-like rubber members 63 and 64 stretched in the air under a constant tension, but the guide means 114 and 115 move synchronously with the corresponding conveyers 100 and 101. Even if the distance (axial distance) between the winding position K and the left and right standby positions L and R is large, the belt-shaped rubber member between the corresponding conveyors 100 and 101 and the guide means 114 and 115 63 and 64 do not swing and the distance between them does not change, and as a result, the bending and twisting generated in the belt-like rubber members 63 and 64 is reduced.

Next, the operation of the first embodiment will be described.
Now, it is assumed that the winding means 85 is located at the winding position K and the tire intermediate 13 is rotating around the axis. At this time, the belt-shaped rubber member 63 of a predetermined type pulled out from the storage case 95 by the operation of the transport conveyor 100 is sent out toward the hopper 61 of the winding means 85. The member 63 is guided while being given a constant tension by the guide means 114 located at the rear of the conveyor 100, and then supplied to the hopper 61 of the winding means 85.

  When the belt-like rubber member 63 is supplied to the winding means 85 in this way, the belt-like rubber member 63 is transferred upward while being heated by the screw 56, and then from the extrusion head 65 of the winding means 85. It is extruded as a narrow band-shaped rubber member 67. At this time, the winding means 85 is moved along the outer surface of the tire intermediate body 13 by turning by the drive mechanism, and the belt-shaped rubber member 67 of a predetermined type pushed out from the winding means 85 is moved to the tire intermediate body. For example, a base tread is formed by supplying to the outer surface of 13 and winding it spirally. At the time of such winding, the remaining winding means 86 stands by at the left standby position L separated from the winding position K to the left in the axial direction.

  When the winding operation of the belt-shaped rubber member 67 around the tire intermediate 13 by the winding means 85 as described above is completed, the motors 24 and 30 are operated to rotate the screw shafts 22 and 28, and the moving table 82, that is, the moving table The main bodies 18 and 19 are moved along the guide rail 17 to the right in the axial direction. At this time, since the winding means 85 and 86 and the transfer conveyors 100 and 101 are supported by the moving table 82, they are integrally moved synchronously, and there is no change in their relative positional relationship. At this time, the motors 116 and 117 are operated to rotate the screw shafts 109 and 110 so that the guide means 114 and 115 are synchronized with the conveyors 100 and 101 so that the relative positional relationship in the left-right direction does not change. Move.

  The movement of the moving table 82 stops when the winding means 85 reaches the right standby position R from the winding position K and the winding means 86 reaches the winding position K from the left standby position L, respectively. Thereafter, the winding means 86 that has moved to the winding position K is similar to the above, and the belt-like rubber member 64 of a different type from the storage case 96 and the conveyor 101 is fed from the extrusion head 66 of the winding means 86. It is extruded as a narrow band-shaped rubber member 68, supplied to the outer surface of the tire intermediate 13 and wound in a spiral shape. As a result, the cap tread is affixed to the outer side of the tire intermediate 13, more specifically the base tread, and the tread is formed as a whole.

  As described above, when different types of belt-shaped rubber members are wound around the tire intermediate body 13, the winding means at the winding position K is moved to the right or left standby position R or L by the movement of the moving base 82, and the right side. Alternatively, the winding means at the left standby position R or L is moved to the winding position K. At this time, the corresponding winding means 85, 86 and the conveyors 100, 101 are moved synchronously, and their relative axial directions are changed. Specifically, in order not to change the positional relationship, each conveyor 100, 101 is always located behind the winding means 85, 86 even if the corresponding winding means 85, 86 moves. Even if the winding means 85 and 86 move as described above, the belt-like rubber members 63 and 64 that are always stretched between the winding means 85 and 86 and the conveyors 100 and 101 are swung, and the corresponding winding There is no change in the relative distance M between the means 85 and 86 and the conveyors 100 and 101. As a result, bending and twisting generated in the belt-like rubber members 63 and 64 during winding are reduced. This prevents a situation where the belt-like rubber members 63, 64 are tangled or cut off in the middle.

    FIG. 4 is a diagram showing Embodiment 2 of the present invention. In this embodiment, instead of omitting the storage cases 95 and 96 in the first embodiment, different types of belt-like rubber members 63 and 64 are temporarily stored, and the belt-like rubber members 63 and 64 are respectively wound many times. Further, rolls 123 and 124 are provided as free-rotating storage means. Since the belt-like rubber members 63 and 64 are wound around the rolls 123 and 124, when the belt-like rubber members 63 and 64 are pulled out from the rolls 123 and 124 by the transport conveyors 100 and 101, the belt-like rubber members 63 and 64 are pulled out. Thus, no tensile force due to catching or the like is generated, thereby preventing the belt-like rubber member from being cut. Other configurations and operations are the same as those of the first embodiment.

    In the above-described embodiment, the tire intermediate 13 supported by the forming drum is used as the wound body. However, in the present invention, a hard core having the same outer shape as the inner surface of the product tire is used. Also good. Further, in the above-described embodiment, as the winding means 85 and 86, the belt-like rubber members 63 and 64 received through the hoppers 61 and 62 are heated, and then extruded from the extrusion heads 65 and 66 as the belt-like rubber members 67 and 68. Although the extruders 54 and 55 and the applicator rolls 77 and 78 were used, in the present invention, the belt-like rubber member supplied from the feeding means is supplied to the wound body as it is and is constituted by an affixing roll mechanism for winding. You may do it.

  Furthermore, in the above-described embodiment, the conveyors 100 and 101 as the sending means are attached to the moving table 82 so that the conveyors 100 and 101 and the winding means 85 and 86 are moved synchronously. In the present invention, the delivery means and the winding means may be moved synchronously by driving the delivery means with a separate drive mechanism. In the above-described embodiment, the conveyors 100 and 101 are installed immediately after the winding means 85 and 86. However, in the present invention, they may be installed separately from the winding means.

  Further, in the above-described embodiment, the movable table 82 is configured by the two movable table bodies 18 and 19 that are individually driven. In the present invention, the movable table bodies 18 and 19 are connected by a connecting member. Alternatively, it may be composed of a single plate-like body and moved in the axial direction by a single drive mechanism. Furthermore, in the above-described embodiment, the motors 24 and 30 are operated synchronously. However, in the present invention, the motors 24 and 30 may be operated individually at different times.

  In the embodiment described above, the two winding means 85 and 86 are spaced apart in the axial direction of the tire intermediate 13. In the present invention, however, three or more winding means are provided in the axial direction. You may make it install apart. At this time, the same number of delivery means and guide means as the winding means are provided.
