DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for winding a linear material, and more particularly to a method for winding a linear material, particularly a deformed soft linear material having an opening such as a concave groove such as a gasket. The present invention relates to a winding method capable of neatly aligning and winding without occurrence of wrinkles, a linear material guide mechanism, a soft tension mechanism, a vertical and horizontal traverse mechanism, and a winding apparatus provided with these mechanisms.

[0002]

2. Description of the Related Art Conventionally, in order to wind a wire material such as a hose or a cord on a bobbin, a traverse shaft having a predetermined pitch is provided in parallel with the bobbin shaft and wound on the traverse shaft. A traverse table provided with a pair of guide rollers and / or a traverse arm for regulating the feeding position of the linear material is screwed together, and by rotating the traverse shaft, the outer diameter of the linear material on which the traverse platform can be wound up. It traverses at an equal pitch, thereby regulating the feeding position of the linear material, and in the movement passage of the traverse table corresponding to each flange position on both sides of the bobbin, the traverse table or one side thereof is protruded. A method is generally adopted in which a limit switch or the like is provided which engages with the projecting piece and gives a reverse rotation command to the traverse table, and the traverse table movement direction is sequentially switched at each flange portion on both sides of the bobbin to take up. Are (Japanese Utility Model 51-53424 issue,
Japanese Patent Publication No. 60-39621, Japanese Patent Publication No. 2-1261, etc.).

[0003] Regarding the intermittent movement of the traverse table in the lateral direction, for example, Japanese Patent Publication No. 14261/1991 discloses a rotary encoder that generates 16 pulse signals per rotation on the rotation shaft of a winding drum (bobbin). Such a pulse signal generating means is provided, and the pulse signal of the pulse signal generating means is counted by a counter, and when the count reaches a preset count, a traverse read signal is generated from the counter. When input to the means, a pulse motor that drives an annular chain (functionally equivalent to a traverse shaft) connected to the traverse body via a ratchet or the like is rotated by a predetermined rotation angle so that intermittent traverse can be performed. The disclosed winding device is disclosed.

That is, the timing at which the traverse read signal is generated is set each time the counter counts 15 pulse signals. Therefore, the traverse read signal is generated at the stage when the winding drum has rotated 15/16, and the pulse motor Is rotated by a fixed pulse to traverse the traverse body by a fixed amount, and at the same time, the count value is reset by the reset signal in the counter, and the counting is restarted from the beginning. In other words, every time the winding drum rotates 15/16, the traverse main body moves by one pulse, and the linear material to be wound skews so as to be shifted by a predetermined pitch in the horizontal direction, and is thus fixed to the winding drum. The wound linear material is always aligned and wound from a line parallel to the winding drum axis at the fixed position of the leading end of the linear material.

[0005]

By performing the intermittent traverse as described above, it is possible to arrange and wind the linear material. However, especially when the linear material to be wound is a soft material, the distal guide portion of the traverse arm interferes with the oblique portion of the linear material, and the distal guide portion is formed on the loop of the adjacent linear material already wound. , And there is a problem that a turbulence occurs. Also, when the linear material to be wound is a deformed soft linear material having an opening such as a concave groove, the conventional intermittent traverse moves only in the lateral direction, so that the tip guide portion of the traverse arm is linear. It is easy to hook the opening edge of the material, especially at the return position of the bobbin flange, because it traverses while skewing so as to cross the skewing part of the already wound lower layer material loop. The edge of the opening is hooked up and turned up, causing not only a winding disorder but also a deformation of the product.

Further, in the conventional winding device, a method of winding a linear material directly onto a bobbin from a final guide roll on a traverse table disposed at a position separated from the bobbin, and a guide arm (traverse arm) However, when the linear material is wound directly from the final guide roll onto the bobbin, if the tension of the linear material is loose, it is difficult for the linear material to faithfully follow the final guide roll. The take-up pitch is indeterminate and locally uneven, twisting occurs, or the wire gets on a loop of the wound adjacent linear material. When the winding tension of the wire is increased to avoid such a problem, the followability of the wire is improved, but on the other hand, the wire is wound more tightly than necessary,
It becomes easy to lose shape. Further, in the case of a soft wire, particularly a deformed soft wire, when the winding tension is increased, the wire is elongated, and the product is easily deformed, and the movement pitch of the traverse table is easily shifted due to a change in the outer dimensions. Cause problems.

On the other hand, when a linear material is guided using a traverse arm, the followability of the linear material is improved as compared with the case where the linear material is directly wound on a bobbin from a final guide roll, but the winding tension is generally controlled by a potentiometer. Because of this, it was often wound more tightly than necessary. Further, as described above, the traverse operation is not sufficiently followed for various slightly different product dimensions, and it has been difficult to perform satisfactory alignment winding particularly for a deformed soft wire.
Furthermore, the conventional traverse arm and guide section on the linear material supply path have a guide mechanism that takes into account only the external shape of the linear material, and the dimensions and guide method are loose for each product. Therefore, in the case of a wire material product, especially a deformed soft wire material, it is often wound up in a twisted or disturbed state. For this reason, when the wound product is used by a coser, there has been a problem in that the wire material is unwound and workability is poor due to poor winding due to twisting or deformation of the product.

Accordingly, a basic object of the present invention is to provide a winding method and a winding method capable of performing a neat aligned winding on a linear material of various shapes and materials without causing disturbance or deformation. It is to provide a device. Furthermore, an object of the present invention is to maintain a constant winding state without causing deformation, deformation and winding disorder of various wire materials, and without causing product deformation particularly on deformed soft wire materials. An object of the present invention is to provide a traverse mechanism that can be wound and a winding device provided with the traverse mechanism. It is another object of the present invention to provide a soft tension mechanism that can always wind up with a constant appropriate tension, and a winding device including the same.
Still another object of the present invention is to provide a guide mechanism for performing a neat aligned winding in a winding device for a linear material, particularly without twisting or deforming a deformed soft linear material.

[0009]

In order to achieve the above object, a first aspect of a method for winding a linear material according to the present invention is a bobbin which is driven to rotate by a winding shaft. A predetermined rotation slightly smaller than a rotation angle of 360 ° corresponding to one rotation of the winding shaft when the linear material is aligned and wound through a tip guide portion of a traverse arm which can reciprocate in the axial direction of the bobbin. Each time the winding shaft rotates by an angle, the traverse arm is intermittently moved in the axial direction of the bobbin, so that each loop of the linear material wound on the bobbin is substantially parallel to a plane perpendicular to the bobbin axis. In this manner, the winding is performed such that the winding start position of each loop of the linear material precedes the winding start position of the previously wound loop by a predetermined distance.

By performing the intermittent traverse in the lateral direction in this manner, each loop of the linear material is wound in a parallel state, not spirally, with respect to the bobbin. Are intermittently traversed at an earlier timing so as to be at a predetermined angle with respect to the axis of the bobbin, so that the tip guide portion of the traverse arm interferes with the previously wound linear material or climbs up. And the wire can be wound up while always making the side surface of the tip guide part slide in contact with the side surface of the wire material wound up earlier. Not only materials, but also irregularly shaped wires such as gaskets,
Aligned winding can be performed without causing turbulence or deformation.

In a second aspect of the method for winding a linear material according to the present invention, the traverse arm is returned in a reverse direction each time the linear material is wound around the bobbin by one layer. It is characterized in that it is forcibly lifted and traversed by a predetermined height in the radial direction of the bobbin to wind up a linear material forming the next layer. By employing such a vertical traverse, aligned winding can be performed without causing winding disorder or product deformation. In other words, the conventional traverse mechanism moves only in the axial direction (lateral direction) of the bobbin, and the movement of the linear material in the radial direction (longitudinal direction) of the bobbin is exclusively performed by the pushing by the already wound linear material layer. Since it was only lifted, the winding state is likely to fluctuate due to the frictional resistance at the time of pushing up, and it is inclined so that it crosses the skewed part of the already wound lower linear material loop at the return position at the bobbin end. It is easy to cause turbulence when moving, especially when the linear material is a deformed soft linear material such as a gasket having a concave groove opening, the tip guide portion of the traverse arm hooks the opening edge of the linear material. Although the product was turned up, the product was likely to be twisted, deformed and turbulent, but the traverse arm was forcibly lifted at the return position at the bobbin end as in the method of the present invention. No problems UNA, wound into a linear material is returned at the bobbin end can be performed smoothly. Also,
Even if the bobbin becomes thicker as the winding progresses, the traverse arm is moved upward by the thickness of the winding layer of the linear material, so that the same winding state can always be ensured.

In a preferred mode, when the traverse arm is returned in the reverse direction at the bobbin end, the tip guide portion of the traverse arm is temporarily lifted slightly above the upper surface of the wound linear material layer and then lowered. Then, the linear material layer is brought into contact with the linear material layer, that is, soft-landed, and the linear material forming the next layer is wound. According to this aspect, the return of the wound linear material at the bobbin end can be performed more smoothly, and in particular, the opening edge portion or the edge portion protruding to the side where the tip guide portion of the traverse arm is easily caught. It is very effective for the winding of the irregularly shaped linear material. In still another preferred aspect, at the end of the bobbin, the wire is wound so as to provide a predetermined gap smaller than the width of the wire to be wound, and the traverse arm is provided on a side surface of the wire having a previously wound loop. Winding is performed so that the side surface of the tip guide portion is in sliding contact. This embodiment is effective in that all the linear materials can be stably aligned and wound without causing shape collapse. This is particularly effective in that it is possible to prevent winding disturbance due to a fall of the loop.

In a third aspect of the method for winding a linear material according to the present invention, the traverse arm is provided in a state where external tension is not applied to the linear material except for the sliding resistance of the guide portion. It is characterized in that a linear material is fed. For example, the linear material is fed in a hanging state, that is, in a state of free tension, between the feed device and the traverse device of the linear material feeding means, and substantially fed into the linear material in a process of feeding to the bobbin. The wire is wound up in a state where only the sliding resistance of the guide portion is applied, that is, in a state of soft tension. by this,
With a moderate tension, a certain winding state can be secured, preventing the winding loop on the bobbin from becoming slack or turbulent when the tension is too small, and firmly winding, losing shape and soft wire when the tension is too strong. Elongation occurring in the case of a shaped material, deformation of a deformed soft wire material, and the like can be easily and effectively prevented. As the soft tension, in general, in the case of a soft wire, particularly a deformed soft wire such as a gasket, the tension applied in the feed direction is preferably in the range of 50 to 150 g / cm ^2. Can be adjusted by

Further, according to the present invention, there is provided a winding device suitable for carrying out the above-described method for winding a linear material. The winding device of the present invention, as its basic aspect,

However, an intermittent traverse mechanism for intermittently moving the traverse arm at a predetermined pitch in the axial direction of the bobbin, and a predetermined height in the radial direction of the bobbin each time the bobbin is wound with one layer of linear material. And a vertical traverse mechanism for moving the traverse arm. As described above, when the linear material is aligned and wound on the bobbin that is driven to rotate by the winding shaft through the tip guide portion of the traverse arm that can reciprocate in the axial direction of the bobbin, the intermittent traverse mechanism and the By adopting the vertical and horizontal traverse mechanism composed of a combination of the traverse mechanisms, the linear material is always aligned and wound in a constant winding state without causing winding disorder or product deformation due to the above-described method and action. be able to.

In a more specific aspect of the winding device of the present invention, the intermittent traverse mechanism includes a detecting device for detecting a rotation angle of a winding shaft of a bobbin, and a reciprocating motion parallel to the winding shaft. A horizontal traverse table provided, and each time the winding shaft rotates by a predetermined rotation angle slightly smaller than a rotation angle of 360 ° corresponding to one rotation of the winding shaft based on the detection signal of the detection device, A drive device for intermittently moving the direction traverse table. On the other hand, the vertical traverse mechanism includes a vertical traverse table attached to the horizontal traverse table so as to be able to reciprocate vertically.
The traverse arm includes a traverse arm that is swingably supported by the vertical traverse table, and guide means provided on the vertical traverse table to guide the linear material to the traverse arm.

Further, the winding device of the present invention comprises a soft tension mechanism for substantially winding the linear material onto the linear material traversing means so that the linear material can always be wound with a constant constant tension. The apparatus further comprises a linear material feeding device for feeding the external material without tension. The linear material feeding device is for feeding the linear material in a hanging state, and preferably, determines whether the height position of the lowermost end of the hanging linear material is within a predetermined range. A plurality of detecting devices are provided for detecting, and the winding speed or the feeding speed of the linear material can be changed according to the height position of the lowermost end of the linear material detected by the detecting device.

Further, according to the present invention, there is provided a guide mechanism in which, when the linear material is, for example, a deformed linear material having an opening groove, the twist or twist of the linear material does not affect the alignment winding.

The intermittent traverse mechanism 20 includes a fixed frame 21 horizontally fixed to a frame 90 and a horizontal traverse table 25 disposed thereon, and the horizontal traverse table 25 has a pair of lower surfaces formed on both sides of a lower surface thereof. The groove 26 is fitted to the pair of rails 22 provided on both sides of the upper portion of the fixed frame 21 so that the fixed frame 21 can slide laterally on the fixed frame 21. Further, a ball screw 23 is provided laterally at a substantially central portion of an upper portion of the fixed frame body 21, while a female screw portion (not shown) at which the ball screw 23 is screwed at a predetermined lower portion of the horizontal traverse stand 25. The ball screw mechanism and the AC servomotor 24 for rotatingly driving the ball screw 23 constitute a driving device for the transverse traverse table 25. The intermittent movement of the transverse traverse table 25 in the transverse direction is caused by the rotation of the winding shaft 65a detected by a detecting device (not shown) such as a rotary encoder mounted on the winding shafts 65a and 65b of the bobbin 50. The ball screw 23 is intermittently rotated by a predetermined amount by the operation of the AC servomotor 24 and is supported on the lateral traverse table 25 and the upper part thereof via a female screw portion screwed thereto.

Further, guide rolls 37 and 38 are disposed at the front and rear ends of the vertical traverse table 31, and a guide device 39 (the details of which will be described later) is disposed near the rear guide roll 38. . Further, a base end of a traverse arm 40 is swingably connected to a rear end of the vertical traverse table 31 via a support member 43. The traverse arm 40 has a gutter-shaped arm main body 41 and a distal end guide section 42 attached to a distal end thereof, and a base end of the traverse arm 40 comes into contact with a retaining section of the support member 43, as shown in FIG. The tip guide portion 42 is adjusted to a height position such that the leading end guide portion 42 is in contact with the outer peripheral surface of the shaft portion 51 of the bobbin 50 at the start of winding. .

The guide device 11 of the linear material feeding device 10
As shown in FIG. 3, the guide device 39 of the vertical traverse mechanism 30 is provided with a guide roll 8 rotatable in the horizontal direction.
1, a partition plate 83 having a T-shaped cross section provided so as to protrude into a groove 82 of the guide roll 81, and the partition plate 83
And a pair of rollers 85 rotatably provided at the upper and lower ends of a shaft 84 for fixing the roller 85. The guide roll 81 has a function of guiding the entire outer shape of a linear material (gasket) 100 having a substantially U-shaped cross section, and on the other hand, a partition plate 83 and a pair of rollers 8.
5 each function as a guide for the opening groove 101 and the opening edge, and the opening groove 1 of the linear material (gasket) 100
In a state where the partition plate 83 is inserted into the sheet 01, the linear member 100 during the feeding is guided so as not to be twisted or twisted. Further, the tip guide portion 42 of the traverse arm 40
Is composed of a frame 86 as shown in FIG. 4, and a linear material (gasket) 10
A partition plate 87 is protruded so as to be inserted into the opening groove portion 101 of the “0”, and is configured so that the linear member 100 can be finally wound up by the bobbin 50 without twisting or twisting.

Referring again to FIGS. 1 and 2, the biaxial turning device 60 has a movable arm 61, and a shaft 62 of the movable arm 61 is supported by a bearing device 63 attached to a frame 90. The movable arm 61 is configured to rotate 180 ° by the operation of the motor 64. A pair of winding shafts 65a and 65b to which the bobbin 50 is mounted are supported at both ends of the movable arm 61, and gears 67a and 67b are fixed to their frame side ends, respectively.
The gear 67a of the winding shaft 65a at the winding position is
The gear 68 meshes with the gear 68 rotatably attached to the gear 0, and the winding starts. When the gear 68 is rotated by the operation of the motor 69, the winding shaft 65a is rotated to start winding the linear material. In addition, concave portions 72a and 72b are formed at two symmetrical positions around the axis 62 on the side surface of the movable arm 61 on the frame side.
Is rotated by 180 ° and becomes horizontal, the cylinder 71
Is actuated, the rod 70 protrudes into one of the concave portions 72b, and the movable arm 61 is fixed at a horizontal position. The bobbin 50 is fixed to the winding shafts 65a and 65b by a fixing tool 66.

Next, the operation of the winding device will be described mainly with reference to FIG. 5 showing a guide mechanism. In the state where the movable arm 61 is fixed at the horizontal position as described above, the tip of the traverse arm 40 is controlled. The distal end of the linear member 100 protruding from the guide part 42 is inserted into a hole (not shown) formed in the shaft part 51 near one flange 52 of the bobbin 50 and fixed. The front end of the linear material can be fixed to the bobbin 50 using a suitable fixing tool such as a pin or an adhesive tape. After setting in this way, the start button is pressed to start winding. The linear material (gasket) 100 is sequentially fed from the feed roll 12 via the guide device 11, but it is necessary to wind the linear material (gasket) 100 with a minimum necessary soft tension in order to prevent deformation of the linear material (gasket) 100. As shown in FIGS. 1 and 5, the linear material 100 fed by the feed roll 12 is released once after exiting between the feed roll 12 and the press roller 13, that is, the hanging free material. In this state, the winding shaft 65a winds up in a free tension state while synchronizing the speed. That is, when the lowermost end of the hanging linear member 100 is detected by the lower sensor 15, the winding shaft 65a
Is increased, the constant speed is maintained as it is when the sensor is detected by the intermediate sensor 16, and the winding speed is decreased when the sensor is detected by the upper sensor 17. Alternatively, the winding speed may be fixed and the feed speed may be increased or decreased.

The linear material 1 sent from the feed roll 12
00 is the guide roll 37, the guide device 39,
The paper is sequentially wound around the bobbin 50 from the distal end guide portion 42 via the guide roll 38 and the traverse arm 40. As described above, after the linear material 100 is fed by the feed roll 12 and once set in a free state, the winding tension is reduced by the guide rolls 37 and 38 and the guide portions 39 and 4.
Although there is only a sliding resistance of 0, 42, it is desirable that unnecessary tension is not applied by such sliding resistance. As a result of experiments, it has been found that in the case of a deformed soft wire such as a gasket, a tension in the range of 50 to 150 g / cm ² is preferable in order to perform aligned winding without deforming the product. Also, as described above, the guide device 39 including the partition plates 83 and 87 inserted into the opening grooves 101 of the linear material (gasket) 100 and the distal end guide portion 4 so that the linear material 100 to be wound is not twisted.
2. Thus, the wire can be wound with a constant tension from the beginning to the end of the winding without causing twisting or deformation of the wire. After the winding is completed, the movable arm 60 is rotated by 180 ° and the winding shaft 65b is rotated.
Of the bobbin 50 mounted on the bobbin is started. During winding, the bobbin 50 of the winding shaft 65a is detached and attached to prepare for the next winding.

FIG. 6 shows a winding mode using the intermittent traverse method of the present invention. In the figure, the arrow indicates the direction of rotation of the bobbin 50, and the hollow arrow indicates the direction of movement of the traverse arm 40. In the intermittent traverse according to the present invention, the servo motor 24 is operated and each loop L ₀ , L
So that the winding start position of ₁ , L ₂ ,... Precedes the winding start position of the previously wound loop by a predetermined distance,
Each time the winding shaft rotates by a predetermined rotation angle slightly smaller than 360 ° of one rotation (corresponding to the length obtained by subtracting the distance between YZ from the circumferential length of the winding layer), the horizontal traverse table is used. 25
And the traverse arm 40 is intermittently moved in the axial direction of the bobbin. Therefore, the line Y at the winding start position and the line Z at the winding end position of each loop are sequentially traversed at an earlier timing so as to have a predetermined angle θ with respect to the axis X of the bobbin. The angle θ varies depending on the size of the linear material to be wound, and the like.
It is preferable to set to about °. With such an intermittent traverse, the loops L ₀ , L ₁ , L
₂ , ... are wound in a parallel state, not spirally, with respect to the bobbin. Since the aligned winding layer is layered on such an aligned winding layer and wound, it is advantageous for winding linear materials having various shapes such as irregular shapes, square shapes, and round shapes. Also, the bobbin width is constant,
Since the width of the wound linear material changes according to each linear material product, the number of winding lines also changes. However, by adopting such an intermittent traverse, the bobbin width− (the number of winding lines + the width of the linear material) )
= It is easy to cope with a change in the remaining width, that is, it is easy to cope with bobbin end face processing.

FIG. 7 shows a conventional winding mode using an intermittent traverse method. In this case, in order to align the winding start positions of the loops, the line Y at the winding start position and the line Z at the winding end position are aligned with the axis of the bobbin. Becomes parallel to X. In this case, the side surface of the tip guide portion 42 of the traverse arm is
Interference with the skewed portion S of 0, the leading end guide portion 42 rides on the loop of the linear material wound up earlier, and winding disorder is easily caused. On the other hand, in the case of the intermittent traversing method as shown in FIG. 6, there is no such a problem as described above, and as shown in FIGS. Since the wire 100 can be slid in contact with the side surface of the wire 100 and taken up while holding down the wire 100, the wire 1
00 is prevented from falling, and no winding disturbance occurs.

When the traverse arm 40 is returned in the reverse direction each time the linear material 100 is wound around the bobbin 50 by the intermittent traverse as described above, the traverse arm is forcibly lifted up by the winding layer height. The bobbin 50 is traversed in the radial direction. The vertical traverse is performed by operating the servo motor 36 to lift the distal end guide portion 42 of the traverse arm 40 by a predetermined height slightly above the upper surface of the wound linear material layer, and then the already wound wire The vertical traverse table 31 and the traverse arm 40 supported thereby are reciprocated in the radial direction of the bobbin so as to be lowered to a position where the tip guide section 42 comes into contact with the shaped material layer. Return of the horizontal traverse table 25 and the vertical traverse table 31
The upward movement of can be performed by a conventionally known method such as a limit switch method.

Conventionally, the movement of the linear material in the radial direction (longitudinal direction) of the bobbin has been performed only by pushing up by the already wound linear material layer. The state is liable to fluctuate, and it is easy to cause winding disturbance when skewing so as to cross the skewing part of the lower layered material loop already wound at the return position at the end of the bobbin. In the case of a deformed soft wire material such as a gasket with a groove opening, the tip guide of the traverse arm hooks the opening edge of the wire material and turns up, causing twisting, deformation and winding of the product. Although it was easy, the traverse arm 40 was forcibly lifted at the return position at the end of the bobbin as in the method of the present invention, so that the bobbin of the wound linear material 100 did not have the above-described problem. Return in it can be performed smoothly.
Further, even if the bobbin 50 becomes thicker as the winding progresses, the traverse arm 40 is moved upward by the thickness of the winding of the linear material 100, so that the winding state can be kept constant from the beginning to the end of the winding. it can.

In the case where the linear material 100 is a deformed linear material having a laterally protruding edge like a gasket, FIG.
As shown in FIG. 0, when the upper linear material loop is wound on the lower linear material loop in a state where the upper linear material loop is aligned and overlaid, the protruding edges abut each other, so that the upper linear material loop falls down. And it becomes easy to produce winding disorder. Therefore, as shown in FIG. 11, it is preferable to wind shifted so as to provide a gap (overlap shift width) W ₁ of the bobbin end when the collar 51 of the bobbin 50. Thereby, the lower-layer deformed linear material 10
The protruding edge of the upper-layer deformed linear material 100 is inserted into the recess formed between the protruding edges of the "0", so that it can be prevented from overturning and can be neatly aligned and wound. Overlapping shift width W ₁
For example, in the case of a gasket, about 1/4 of its width is appropriate, but this width can be appropriately set according to the cross-sectional shape of the linear material. For example, in the case of a circular cross-section, 1/2 is appropriate. Calculation setting intermittent traverse pitch, since a bobbin width W shown in FIG. 12 is constant, based on the width W ₁ is shifted piled according to a linear member for winding a winding column width W _2, was calculated by the following formula values it may be set allocated equally to the product between the gap W ₃ and m. (W−W ₁ ) / (W ₂ + W ₃ ) = number of windings + remainder width excess width / number of windings = m

As described above, since the winding shaft power and the traverse power are separated and the intermittent traverse and the vertical traverse can be operated independently, the height, width, and traverse movement of the linear material can be obtained. By setting numerical values for each point such as traverse timing and turn timing, it is possible to select an operation most suitable for each linear material. By setting the numerical values, it is possible to correspond to various types of linear materials. The present invention is not limited to the above embodiment, and various design changes are possible. For example, in the above-described embodiment, the ball screw was used for driving the traverse table. However, other means having the same function as this, such as a chain drive, can be used. The same applies to the control means. Also, the structure of the guide device can be appropriately designed according to the linear material used. The essence of the present invention is not in such individual means, but in the intermittent traverse mechanism, the vertical traverse mechanism, the soft tension mechanism and the guide mechanism, and combinations thereof, as described in detail above.
