Abstract

When a carcass ply material is produced by sequentially bonding pieces of a ply material cut into stripes, the pieces are precisely bonded without causing strain, partial overlap, gap, or the like. Every time when the cut ply material pieces are transferred from a cutting process section to a bonding process section, two sets of roller units, or left and right roller units, are used to bond a preceding ply material piece and a following ply material piece with the pieces butted to each other at their side edges. Each roller unit (65a, 66a) or (65b, 66b) is provided with a set of upper and lower pressure rollers (62a1, 62a2)(63a1, 63a2) of which each set being paired in the front/rear direction and that are able to come into pressure contact with both ply material pieces. The pressure rollers of one of the roller units (65a, 66a) are moved from central part to one side of the ply material pieces while clamping them at their both side edges, and pressure rollers of the other roller unit (65b, 66b) are moved from central part to the other side of the ply material pieces while clamping their both side edges. This causes the side edges of the ply material pieces to be pulled toward each other to bond them in a butting manner.

 Method and apparatus for producing carcass ply material

 Technical field

 TECHNICAL FIELD [0001] The present invention relates to a method and an apparatus for manufacturing a carcass ply material for tires formed by cutting and joining mainly carcass ply materials for pneumatic radial tires, in particular, strip materials for long plies. It is.

 Background art

 [0002] The carcass layer of a pneumatic radial tire is composed of a layer of force-cass ply material in which the direction of the reinforcing cord made mainly of fibers embedded in the rubber material is the radial direction of the tire, that is, the width direction. Usually, a plurality of carcass ply materials having different widths are laminated.

 [0003] Such a carcass ply material has a length corresponding to the width of the carcass ply material, in which a plurality of reinforcing cords are juxtaposed with each other and covered with a rubber material and embedded in the rubber material. It is formed by cutting and aligning the cut strip-like ply material pieces so that the cut ends form both side ends in the width direction and sequentially joining at the side edges which are non-cut edges.

 [0004] Conventionally, a long carcass ply material piece formed as described above is rolled up and stocked, supplied to a tire molding process, and laminated on a molding drum. Was going to do. In this case, the width and length of the carcass ply differ depending on the tire size, and the widths of the first layer and the second layer in the multi-layered carcass layer also differ, so depending on the type and size of the tire to be manufactured. Therefore, many kinds of carcass ply materials must be formed and stocked as described above, and a considerably large stock space is required in the factory. In addition, the work of selecting and transporting the carcass ply material according to the tire to the molding process and the replacement work are extremely troublesome, which is one factor that hinders the improvement of manufacturing efficiency. In particular, in the case of high-mix low-volume production, it was necessary to frequently perform a changeover operation for exchanging the cart that supports the carcass ply material.

[0005] Therefore, in recent years, during the tire molding process, a carcass ply material having a predetermined length is produced at a position facing the molding drum, and this is directly sent to the molding drum to be wound and molded. An apparatus for this purpose has been proposed.

 [0006] For example, Patent Document 1 discloses that a long ply strip material is cut in a predetermined length in accordance with the carcass width on the tire molding while being fed in the longitudinal direction, and the cut ply material piece ( And the ply material pieces on the conveyor are transferred onto a take-up conveyor arranged in series with the conveyor, and the ply The material piece is moved backward, and the rear side edge is positioned at the joining position set in the middle between the conveyor and the take-up conveyor, and the side edge of the ply material piece is cut next and the conveyor is cut. A method and an apparatus are disclosed in which the side edge of the ply material piece transferred by the butt is abutted and joined at the joining position. In addition, as a device for performing the above-mentioned joining, a frustoconical pulling roller that moves while contacting the upper and lower surfaces of both side edges to be joined is provided so as to be paired up and down. Further, there is also shown an apparatus for joining both side edges of both ply material pieces while pulling them in the abutting direction while sandwiching them from above and below.

 [0007] By the way, as shown in Patent Document 1, the pulling roller for joining runs over the entire length of the joining portion from one end side in the longitudinal direction to the other end side of the ply material piece. Let the edges of both sides of the ply pieces be on each other! In the process where the pulling roller is abutted and joined while being pulled, the pulling roller is moved forward from the one end side toward the other end side, and the degree of pulling (amount) ) Gradually increases, and as a result, the joint state may be distorted or loosened, or overlap may occur, preventing accurate joining.

 [0008] For this reason, in Patent Document 1, the vicinity of the side edges of the two ply material pieces to be joined is pressed by a pressing device so as to join the ply material pieces in a state in which the movement of the ply material pieces is restricted. In this case, excessive pulling can be suppressed and the occurrence of overlap can be suppressed.However, the effect of pulling, that is, the effect of ensuring the butt can not be obtained sufficiently, resulting in partial gaps or incomplete joining. There is a risk of becoming.

[0009] In particular, when both side edges of two ply material pieces are butt-joined to each other, the effect of pulling is ensured, and distortion and slack are not generated, and overlap due to excessive pulling is not generated. Can be accurately joined to obtain a high-quality carcass ply material. It becomes an important element in

 Problems to be solved by the invention

[0010] The present invention solves the above-described problem, and cuts a strip-like ply that is cut from a long ply strip material into a length corresponding to the width of the car power splice material. When joining by joining the side edges of one piece, it can be joined accurately and reliably without causing distortion, slack, partial overlap, or gaps, and a high-quality carcass ply material can be obtained. The present invention provides a method and an apparatus for producing a carcass ply material.

 Means for solving the problem

[0011] The present invention is a method for producing a carcass ply material mainly used for manufacturing a tire, and a long ply strip material is set to a predetermined length set in accordance with the width of the carcass ply material to be produced. A cutting process section for cutting, and a joining process section for sequentially joining the cut strip-shaped ply pieces at the side edges that are non-cutting ends. In the joining process section, the strips cut by the cutting process section The ply material pieces in the shape of a ply material are fed to the joining device part one after the other, with both side edges that are uncut ends, and the rear side edge of the preceding ply material piece and the front side edge of the next ply material piece In a method for producing a carcass ply material, in which the

 When joining by the joining device, an upper and lower roller unit having rotatable contact pressure rollers capable of contacting with both side edges of the butted state of both the ply material pieces in pairs at the upper and lower portions of the joining position. Using two sets of left and right as a set, the pressure roller of the upper and lower roller unit of one of the left and right is one side from the center in the direction in which the both side edges extend in a state where the both side edges are clamped, The pressure rollers of the other upper and lower roller units are moved from the center in the direction in which the both side edges extend in a state where the both side edges are clamped, and are respectively moved by the pressure rollers. By joining the half halves of both side edges so that the edges are pulled toward each other, the full lengths of the side edges are abutted and joined.

[0012] According to this method, the two sets of left and right upper and lower roller units are pulled by the contact pressure roller. The joining of the both side edges accompanied by the shift is performed approximately half by moving in the opposite direction from the vicinity of the center in the extending direction of the both side edges. As a result, the amount of pulling that is less affected by the gathering becomes excessively large and overlaps, and distortion and slack do not occur.

 [0013] In the method for producing the carcass ply material, a part of the left and right upper and lower roller units and the other upper and lower roller units in a vicinity of a central portion in the extending direction of the both side edges. As a result, it is preferable to move it so that it is double pinched. This ensures that the entire length of both side edges can be joined.

 [0014] In particular, there is a time difference between the movement of the left and right upper and lower roller units in the clamping state by the contact roller and the movement of the other upper and lower roller units in the clamping state by the contact roller. After the one upper and lower contact pressure rollers slightly move the vicinity of the center portion in the extending direction of the both side edges in a pinched state, the other upper and lower contact pressure rollers move the same portion near the center portion. After clamping, it is preferable to move both sets of roller units in opposite directions. As a result, as described above, a portion near the center of the extending direction of the both side edges can be double-clamped, and joints can be made while pulling substantially the side portions of the extending edges of the both side edges simultaneously. Thus, it is possible to securely join without causing distortion or slack due to pulling.

 [0015] In the joining step, the joining device having two sets of the upper and lower roller units on the left and right sides, and strip-like ply material pieces sequentially transferred for each cutting action from the cutting step are used at the uncut ends. Between a transfer conveyor that moves forward with a certain side edge forward and backward, and a delivery conveyor that is arranged in series in front of the transfer conveyor and that receives the ply material piece transferred by the transfer conveyor force. The rear side edge of the preceding ply material piece on the delivery conveyor is retracted by the delivery conveyor, and the front side of the next ply material piece on the conveyor The edges can be advanced by the conveyor and positioned so as to abut each other at the joining position by the joining device. As a result, the positioning of both ply material pieces can be easily performed using the feeding and retreating operations by the transport conveyor and the delivery conveyor.

[0016] According to the method for producing the carcass ply material, the produced carcass ply material is transported. The conveyor force can also be sent directly onto the molding drum in the tire molding process. As a result, the carcass ply material to be produced can be sent and used in accordance with the molding cycle on the molding drum, which does not need to be stocked and managed, and the tire molding efficiency can be increased.

[0017] The carcass ply material manufacturing apparatus of the present invention is used for carrying out the above manufacturing method, and a long ply belt-shaped material is set according to the width of the carcass ply material to be manufactured. A cutting process section that cuts to a predetermined length and a joining process section that sequentially joins the cut strip-shaped ply material pieces at the side edges that are uncut ends. The strip-shaped ply material pieces cut at the section are sent to the joining device part sequentially with both side edges, which are uncut ends, back and forth, and the rear end of the preceding ply material piece and the next ply material piece In the carcass ply material manufacturing apparatus in which the front side edge is positioned and butted to a predetermined joining position and joined by the joining device.

 The joining device includes a pair of upper and lower roller units each having a rotatable contact pressure roller that can contact and press against both side edges of the butted state of the two ply pieces at the upper and lower portions of the joining position. The two upper and lower roller units and the other upper and lower roller units are connected to a moving means for moving the upper and lower units in synchronization with each other. The one roller unit has a force in the vicinity of the center in the direction in which the both side edges extend, and the other roller unit in the state where the both end edges are clamped by the contact pressure roller. Are provided so as to move in the opposite directions from the center to the other side, respectively, and the both sides of the roller unit are moved by the contact pressure roller by the movement of the roller unit in the clamping state. The two end edges are joined to each other such that the end edges are bowed toward each other.

[0018] According to this manufacturing apparatus, the rear side edge of the strip-shaped ply material piece cut in the cutting step section and the front side edge of the next ply material piece are joined by the joining device. In this state, the two side edges are clamped so as to be pulled toward each other by the contact pressure rollers of the two sets of upper and lower roller units. At this time, one of the upper and lower roller units on the left and right is one side from the vicinity of the central portion with the both side edges sandwiched by the pressure roller, and the other upper and lower roller units are the pressure roller. By both With the side edge clamped, the force near the center moves to the other side, and the both side edges are brought into contact with each other by pulling the both side edges by the pressure contact rollers. Therefore, the ply material pieces can be joined accurately and reliably without causing any overlap or distortion caused by excessive bowing, and the above method can be carried out satisfactorily.

[0019] In the carcass ply material manufacturing apparatus, the front and rear contact pressure rollers in each roller unit are in contact with the edges of the both sides toward the side between both rollers as viewed from the plane of extension of the axial center. Inclined so as to be on the front side in the moving direction in the state, and are arranged so as to draw both side edges of the two ply material pieces joined by the rotation accompanying the movement in the pinched state be able to. Accordingly, the both end edges of the two ply material pieces to be joined can be reliably pulled and joined by the movement of the contact pressure roller in the contact pressure state.

In addition, a separating guide plate that regulates and positions the overlapping of both side edges of the two ply material pieces that are abutted with each other can be provided. As a result, excessive pulling and overlapping should not be restricted when the two side edges of the two ply material pieces positioned and abutted by the joining device are separated from each other and then joined. Therefore, both side edges can be reliably joined.

[0022] In the carcass ply material manufacturing apparatus, the delivery conveyor is capable of forward and reverse rotation, and the ply material piece is moved backward by reverse rotation after the preceding ply material piece is conveyed to a predetermined position. Position the rear side edge at the joining position by the joining device, It may be provided so as to rotate forward and transport to a predetermined position after completion of joining by the joining device. Thereby, positioning of both ply material pieces can be performed using a conveyor.

 [0023] In the carcass ply material manufacturing apparatus, the cutting step section transfers the ply strip material pulled out in the longitudinal direction from the supply section intermittently along the feeding section by the predetermined length. An apparatus, a cutting device that cuts the leading end portion of the strip-shaped material into the predetermined length for each transfer by the transfer device, and a cut strip-shaped ply material piece is transferred to the joining process section And the joining process section intermittently conveys the strip-shaped ply material pieces sequentially transferred from the cutting process section, with both side edges that are non-cutting ends as front and rear.

Yes. In the joining process section, each time the strip-shaped ply material pieces are sequentially transferred from the cutting process section onto the transport conveyor, the strip-shaped ply material pieces are intermittently transported by the transport conveyor. The side edge on the rear side of the preceding ply material piece on the delivery conveyor transferred from the conveyor and the side edge on the front side of the next ply material piece to be conveyed next by the conveyor By using the retreating of the conveyor or the feeding operation of the conveyor, it is possible to position and abut at the joining position by the joining device, and thus the both side edges can be joined sequentially.

[0025] The delivery conveyor moves the ply material piece backward by positioning the preceding ply material piece to a predetermined position, and positions the rear side edge at the joining position by the joining device. At the same time, after completion of the joining by the joining apparatus, it is rotated forward and conveyed to a predetermined position The operation is controlled as follows.

Further, screw shafts 95 and 96 are arranged along the base members 81 and 82, and engaging blocks 97 and 98 attached to the movable support plates 71 and 75 are screwed onto the screw shafts 95 and 96, respectively. The screw shafts 95, 96 are provided so as to move in the left-right direction. The upper and lower screw shafts 95, 96 are synchronized with a pulley 95a, 96a provided at one end (the right end in Fig. 12). And is provided to rotate. A servo motor 100 for driving is connected to one of the upper and lower screw shafts, for example, the lower screw shaft 96 so that power can be transmitted, and when the screw shafts 96 and 95 are rotated by the servo motor 100, the upper and lower screw shafts 96 and The movable support plates 71 and 75, that is, the upper and lower roller units 65b and 66b supported by the movable support plates 71 and 75, are configured to move mainly in the right half as viewed from the conveying conveyor 40 side.

 [0071] The movement of the two left and right roller units 65a, 66a and 65b, 66b driven by the servo motors 90, 100 as described above is controlled in combination with the lifting operation by the cylinder devices 72, 76, respectively. At the time of joining, the two side edges bl, b2 are sandwiched and moved from the vicinity of the center to the opposite side.

 [0072] In particular, the left and right upper and lower roller units 65a and 66a are moved in a state of pressure by the contact roller, and the other upper and lower roller units 65b and 66b are moved in a state of pressure by the contact roller. Is set so that the two side edges bl and b2 move in a state where a part in the vicinity of the central portion in the extending direction is double pinched.

 [0073] That is, the left and right upper and lower roller units 65a and 66a are moved in the pressure-contacted state by the pressure-contact rollers 62al and 62a2 and 63al and 63a2, and the other upper and lower roller units 65b and 66b are the pressure-contact rollers. First, the upper and lower roller units 65a, 66a (or 65b, 66b) are connected to the pressure rollers 62al, 62a2, and 63al with a time difference from the movement in the clamping state by 62al, 62a2 and 63al, 63a2. , 63a2 slightly moves near the center in the extending direction of the both side edges bl, b2 in a pinched state, and then the other upper and lower roller units 65b, 66b (also 65a, 66a) force S, The pressure roller 62al, 62a2 and 63al, 63a2 sandwich the same part near the center, and then the left and right roller units 65a, 66a and 65b, 66b are moved in opposite directions. Is done.

[0074] After the preceding strip-shaped ply material piece b is transferred to the delivery conveyor 50 side, the side edge b2 on the rear side of the ply material piece b on the delivery conveyor 50 and the conveyor 40 Before positioning the front side edge bl of the upper ply piece b on the joining position, the two left and right roller units 65a, 66a and 65b, 66b The lower roller units 66a and 66b near the center of the direction (width direction of the conveyor 40) are raised to the height at the time of joining as shown in FIG. 12, for example. The separation guide plates 79 and 79 in the belts 66a and 66b are held in a state of projecting upward from the upper surfaces of the transport conveyor 40 and the delivery conveyor 50, or held in a standby state before ascending.

 Reference numerals 91 and 92 in the figure are pressing members that press the vicinity of the joining position of the ply material piece b when joining by the joining device 60, and can be moved up and down by a cylinder device (not shown). Is provided. This pressing member may be omitted.

 [0076] It should be noted that the delivery side of the delivery conveyor 50 in the joining process section A2 usually passes through a part of the dancer 101 that can hold the carcass ply material C produced by joining the ply material pieces b to a certain length. Thus, the carcass ply material C is provided so that it can be directly sent to the molding drum D at the position where the carcass layer is pasted and formed in manufacturing the tire.

 [0077] A method and an operating state of manufacturing a carcass ply material using the manufacturing apparatus of the above-described embodiment will be described.

 [0078] Production is started by operating the apparatus. In advance, the long ply strip material B is pulled out from the supply unit 1 onto the feed table 5, and the tip side portion thereof is placed on the first table 5a on the supply side. Pull out to a predetermined position. In this state, the holding means 13 provided in the transfer device 10 is lowered, and the leading end portion of the belt-like material B is held by the holding means 13 so as to be pressed onto the first table 5a. At the same time, the piercing needle 26 of the drilling means 25 provided below the first table 5a is raised by the operation of the cylinder device 28, and the tip side portion of the strip material B on the first table 5a is A needle hole for releasing air during molding, which will be described later, is formed in the required range.

 Thus, the holding means 13 lifts the end portion of the band-like material B while being held by the holding means 13 such as suction, and the moving means 11 provided in the transfer device 10 operates to move the predetermined length by the operation. Transfer to the second table 5b. Thereafter, the holding means 13 of the transfer device 10 releases the holding of the band material B and returns to the original position. At the same time as the holding means 13 of the transfer device 10 returns to the original position, the holding means 35 of the transfer device 30 is moved from above the front end side portion of the band-shaped material B on the second table 5b. Lower and hold down the tip side.

In this state, the first table 5a and the second table 5b of the feed table 5 Then, the cutter device 20 provided in the separation part is operated, the strip material B is cut in a direction perpendicular to the longitudinal direction by the cutter blade 21, and the tip side part is cut as a strip-like ply material piece b. Then, after the cutting, the ply material piece b cut by the holding means 35 of the transfer device 30 is lifted while being held by a means such as suction and transferred to the transfer conveyor 40 of the joining process section A2. To do.

 [0081] As described above, the front end side portion of the strip-shaped material B that is intermittently transferred is cut into a predetermined length in accordance with the transfer operation, and each cut ply is cut for each cutting action. The material pieces b are sequentially transferred onto the conveyor 40 of the joining process part A2.

 [0082] In the joining process section A2, each time the ply material piece b is transferred onto the transport conveyor 40, the transport conveyor 40 is actuated to act as uncut ends of the ply material piece b. Move forward and backward. The first ply piece b immediately after the start of operation is placed on the front as it is and transferred onto the delivery conveyor 50. After the first ply material piece b is transferred to the delivery conveyor 50, a predetermined joining by the joining device 60 installed between the transport conveyor 40 and the delivery conveyor 50 is performed as follows. Position to position.

 [0083] The delivery conveyor 50 retreats the side edge b2 on the rear side of the ply material piece b by reverse rotation after the ply material piece b sent from the transport conveyor 40 is transferred to a predetermined position. At the same time, the side edge b2 is detected by the sensor 57 and the drive is controlled, whereby the side edge b2 is moved back to a predetermined joining position by the joining device 60 and positioned. On the other hand, the conveyance conveyor 40 conveys the next transferred ply material piece b forward, and detects the side edge bl on the front side by the sensor 47 to control the driving, thereby controlling the side edge. The edge bl is transported to the predetermined joining position by the joining device 60 and positioned. In this way, the rear side edge b2 of the preceding ply material piece b and the front side edge bl of the next ply material piece b are positioned so as to abut at the joining position by the joining device 60. To do.

 [0084] In the state of positioning as described above, the roller unit 65a, 66a and 65b, 66b with a pair of upper and lower left and right threads provided in the joining device 60 are joined as follows. To do.

This bonding operation state will be described with reference to FIGS. 21A to 21E schematically showing operation steps. [0086] In FIG. 21A, the two sets of left and right roller units 65a, 66a and 65b, 66b are in the vicinity of the center of the joining position in the longitudinal direction (the width direction of the transfer conveyor 40), and are respectively before being lowered and raised. In the waiting state, the side edges of the two ply pieces b, b are positioned in this state.

 [0087] Before this positioning, the lower roller units 66a and 66b are raised to the height at the time of joining, and the separation guide plates 79 and 79 included in both the roller units 66a and 66b are transferred to the conveyor 40 and the delivery. It can also protrude above the upper surface of the conveyor 50.

 [0088] After the positioning is completed, the joining device 60 is joined. First, as shown in FIG. 21B, for example, as shown in FIG. 21B, the upper roller unit on the left side (left side in the figure) on the left side as viewed from the conveyor 40 side. 65a is lowered by the cylinder device 72, and the lower roller 66a is raised to the height at the time of joining by the cylinder device 76, so that the upper and lower roller units 65a, 66a Rollers 62al, 62a2 and 63al, 63a2 [from here, the vicinity of the center part in the extending direction of the both side edges bl, b2 which are abutted is clamped. In this state, as shown in FIG. At this time, the upper and lower roller units 65b and 66b on the other side (the right side in the figure) are moved in the same direction as the movement of the one roller unit 65a and 66a while being not clamped as shown in the figure.

 [0089] Thus, when the other roller unit 65b, 66b force reaches the portion where the contact roller 62al, 62a2 and 63al, 63a2 of the one roller unit 65a, 66a is nipped, the movement is performed. -Stop and lower the other upper roller unit 65b and lower the lower roller unit 66b, as shown in Fig. 21D. Contacting rollers 62al, 62a2 and 63al, 63a2 [From here, the vicinity of the center of both side edges bl, b2 is pressed, in particular, the same portion as that pressed by the one roller unit 65a, 66a. Thereafter, the left and right roller units 65a, 66a and 65b, 66b are simultaneously moved in opposite directions to one side and the other side while maintaining the above-mentioned clamping state. That is, as shown in FIG. 21E, the both ends of both side edges bl, b2 are moved to the outside.

[0090] During the movement in the pinched state, the contact pressure rollers 62al, 62a2 and 63al, 63a2 of the roller units 65a, 66a and 65b, 66b are both viewed from the extension linear force plane of the axis. Since the side between the rollers is inclined so as to be on the front side in the moving direction in the state of contact with both side edges bl, b2, so that they are abutted by the rotation accompanying the movement in the pinching state The two ply material pieces b, b that are positioned act so as to attract the side edges bl, b2. In addition, the front and rear contact pressure rollers 62al, 62a2 and 63al, 63a2 rotate in synchronism with each other, so that the front and rear side edges bl, b2 can be drawn in a balanced manner. Accordingly, it is possible to join the two side end edges bl 1 and b2 while pulling each other half-way toward each other without pressing the butted portion from the top and bottom.

[0091] In particular, using two sets of left and right upper and lower roller units 65a, 66a and 65b, 66b, joining by clamping with the contact pressure rollers 62al, 62a2 and 63al, 63a2 provided in the left and right units, Since both the side edges bl and b2 move in the opposite direction from the center in the extending direction to the opposite sides and perform approximately half of each part, the degree of pulling by the left and right contact pressure rollers respectively, The distortion caused by the pulling action of the contact pressure roller (being inclined toward the front in the moving direction) is eliminated. For this reason, the ply material pieces b and b, which are less affected by pulling, can be joined with high accuracy so that they are not obliquely distorted or wavy.

 [0092] When the separation guide plate 79 is provided as shown in the figure, both side edges bl, b2 of the two ply material pieces b, b to be abutted are separated from each other. Therefore, both side edges bl and b2 can be securely joined while restricting excessive pulling and overlapping.

 [0093] Further, as described above, the left and right upper and lower roller units 65a and 66a are moved by the contact pressure roller and the other upper and lower roller units 65b and 66b are contacted by the contact pressure roller. Insufficient pinching in the vicinity of the center by moving a part of the side edge bl, b2 near the center in the extending direction with a time difference from the movement in the pinching state. It can be joined in this way without causing

[0094] As described above, when one joining is completed, the delivery conveyor 50 is driven and rotated, and the ply material piece b on the delivery conveyor 40 joined as described above is drawn into the delivery conveyor 50 side. Thus, the ply material piece b is sent to a predetermined position, and thereafter, by the same operation as described above, the preceding ply material piece b on the delivery conveyor 50, that is, joined as described above. The ply material piece b at the end of the carcass ply material C and the side edges of the next ply material piece b on the transport conveyor 40 are positioned, and the joining by the roller units of the joining device 60 is performed in the same manner as described above. Done.

 [0095] Every time the strip-like ply material piece b cut in this way is transferred from the cutting process section A1 onto the conveying conveyor 40, the above operation is repeated to remove the ply material piece b. By sequentially joining, a continuous carcass ply material C can be produced.

 [0096] The continuous carcass ply material C produced as described above is sent from the delivery conveyor 50 onto a carriage and stocked, and can be pulled out for use. The above is used by cutting to the required length on the molding drum D while being sent and pasted onto the molding drum D of the tire molding process directly via the dancer 101 as shown in the illustrated embodiment. Is preferred.

 [0097] The production device for the carcass ply material C composed of the cutting process part A1 and the joining process part A2 described above is used for attaching and molding one layer of the carcass ply material in the tire molding process in manufacturing the tire. In addition, for example, as shown in FIG. 22, in the process of attaching and molding two layers of the first carcass ply material C1 and the second carcass ply material C2 having different widths, both the carcass ply materials CI, C2 It can be done by arranging two production devices El and E2 corresponding to the above.

 In the case of FIG. 22, although detailed description is omitted, the basic configuration of the joining device 60 and the like of the joining process part A2 is the same as that of the above-described embodiment, and the same reference numerals are used for the main parts constituting the same. It is attached. In FIG. 22, the first fabrication device E1 produces the first carcass ply material C1, and the second production device E2 produces the second carcass ply material C2. The belt-like material B force is also applied with different lengths of the ply pieces b to be cut. In particular, in the case of the embodiment of FIG. 22, the transfer device 30 for transferring the strip-like ply material piece b cut in the cutting process section A1 onto the transport conveyor of the joining process section A2 is one.
