DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a self-fabric woven in the loom
To a method for winding the cloth roll which is supported a derived end portion on the loom.

[0002]

2. Description of the Related Art A cloth (woven cloth) woven by a loom crosses a swingable press roller provided on the loom, and is arranged in parallel with the press roller and is rotated by the loom. It is wound up. During the winding of the woven fabric, since the woven fabric is under tension, the press roller receives a pressing force from the woven fabric surrounding the woven fabric and presses the peripheral surface of the woven fabric wound on the cross roll. Due to this pressing, occurrence of wrinkles at the time of winding the woven fabric is prevented. By the way, the press roller, at the time of winding the free end of the woven fabric around an empty cross roll that is not wound with the woven fabric,
The woven fabric is separated from the wound cross roll, and a space is formed between the woven fabric and the cross roll. A spring force is applied to the press roller to separate the press roller. The free end of the woven fabric extending in the direction of rotation along the peripheral surface of the cross roll is guided into the space by contact with the rotating cross roll, and further from the cross roll and the press roller. It is guided between a part of the woven cloth reaching the cross roll and thereby wound around the cross roll. (Japanese Patent Laid-Open No. 5-
25742)

[0003]

[SUMMARY OF THE INVENTION] However, in practice, the free end of the fabric is stopped once the movement against the part from the press roller for warp caused during cutting of the fabric extending to the cross roll Then, after a portion connected to the free end of the woven fabric is bent and accumulated in the space, these are guided at once between the cross roll and a part of the woven fabric around the press roller. As a result of a part of the woven fabric folded in multiple layers being wound around the cross roll, wrinkles are generated. Accordingly, it is an object of the present invention to prevent the occurrence of wrinkles when winding the free end of a woven fabric around a cross roll.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a swing roller and a rotatable press roller provided on a loom, and the circumference of a cross roll arranged parallel to the press roller and driven to rotate by the loom. Guiding the free ends of the woven fabric wound on the cross roll, extending along the plane in the direction of rotation of the cross roll, between the press roller and the cross roll, which are spaced apart from each other; Next, the press roller is swung toward the cross roll so as to sandwich the free end of the woven fabric.

[0005]

According to the present invention, when the press roller is swung toward the cross roll so as to sandwich the free end of the woven fabric between the press roller and the cross roll, The tension between the press roller and the woven cloth surrounding the press roller disappears, a part of the woven cloth is loosened, and the woven cloth hangs down from the press roller and the cross roll. Of the woven fabric sandwiched between the cross roll and the press roller
Until the looseness of a part of the woven fabric is eliminated, the free end portion receives the rotational force of the cross roll and receives the guide action of the press roller that is driven to rotate, and moves along the cross roll and its peripheral surface. It is guided smoothly and reliably between the woven fabric and the woven fabric extending, thereby preventing the occurrence of wrinkles.

FIG. 1 schematically shows the front of a loom 10. FIG. A cross roll 14 for winding up a cloth (woven cloth) 12 woven by a weaving mechanism (not shown) at the rear of the loom 10 is disposed at the front of the loom 10. Cross roll 1
Numeral 4 is a tubular body, and both ends thereof are supported by a pair of rotating shafts 16 (FIG. 9). The cross roll 14
The woven fabric 12 wound around the cross roll 14 is wound in one direction (clockwise in the drawing) by the rotating shaft 16. Hereinafter, a roll composed of the cross roll 14 and the woven fabric 12 having a predetermined length wound around the cross roll is referred to as a full roll.

The rotating shafts 16 are rotatably supported by a pair of frames 18 defining both sides of the loom 10 so as to be rotatable and movable in the axial direction. Each rotating shaft 16
The rotation and the axial movement of the motor are performed by the operation of a motor (not shown) and a power unit including a torque transmitting mechanism (not shown) of the motor. Both rotating shafts 16 are driven and rotated while the loom 10 is operating, that is, during weaving.

Each end face of the cross roll 14 is provided with a pair of grooves 14a extending in the diameter direction. On the other hand, a pair of projections 16a (FIG. 9) that can be fitted into both grooves 14a of the cross roll and an end that can be fitted into holes 14b of the cross roll 14 that are continuous with both projections 16a are provided at the end of each rotating shaft 16. An annular projection 16b is provided. Cross roll groove 14a
The cross roll 14 is supported by the loom 10 by fitting the projections 16a and 16b of the respective rotating shafts into the holes 14b.
The fitting is performed while the cross roll 14 is disposed on an extension of the rotating shafts 16.

A pair of arms 20 are provided to support the cross roll 14 on an extension of the rotary shafts 16.
Each arm 20 has a base 20 a rotatably supported on both frames 18 of the loom and fixed to a shaft extending parallel to the rotation shaft 16, and a hook-shaped tip 20 b for receiving each end of the cross roll 14. .

The woven fabric 12 wound around the cross roll 14
In order to prevent the occurrence of wrinkles on the peripheral surface 23 of the woven fabric, a press roller 24 extending across the peripheral surface 23 of the woven fabric and exerting a pressing force on the surface is provided. Press roller 24
Is swingable toward a cross roll 14 extending in parallel with this, and is rotated in contact with the cross roll 14, that is, the cross roll 14 itself or the woven fabric 12 wound around the cross roll 14.

Referring to FIGS. 1, 2 and 3, the press roller 24 is rotatably supported on one end of a pair of arm members 26 spaced from each other. The other ends of the two arm members 26 are connected to cam members 28 described later in detail.
Via a shaft 30 rotatably supported on both frames 18 of the loom. The shaft 30 is located at a height that does not contact the circumferential surface of the full roll, that is, the circumferential surface 23 of the woven fabric wound around the cross roll 14 by a predetermined length.

A woven fabric 12 extending forward from the rear of the loom 10
Are a plurality of rollers 32 arranged at a height above the shaft 30 and rotatably supported by the frames 18.
After passing through 38, the cam member 28 and the press roller 24 are sequentially contacted and extended to the upper side thereof as shown in FIG. 1, and reach the peripheral surface 23 of the woven fabric of the cross roll 14.

A friction clutch (not shown) is interposed between the rotating shaft 16 and a motor (not shown). The cross roll 14 is rotated at a speed slightly larger than the weaving speed, that is, the feeding speed of the woven fabric from the rear to the front of the loom 10 when the woven fabric is not wound. For this reason, when the woven fabric 12 is wound around the cross roll 14 , the woven fabric is placed in a tension state, and a load is applied to the rotating shaft 16. At this time, a speed difference is generated between the rotating shaft 16 and the motor due to the presence of the friction clutch.
The woven fabric 12 is always placed in tension. Press roller 24
Is applied with a clockwise oscillating force from the woven fabric 12 in the tension state. This rocking power is applied to the cross roll 14
Is a pressing force acting on the circumferential surface 23 of the woven fabric around the woven fabric.

The full roll is moved forward of the loom 10 by moving means 40. As shown in FIGS. 4 and 5, the moving means 40 includes a slider 42 supported by each frame 18 and a supporting member disposed in parallel with the slider 42 and connected to the slider 42 via a hollow connecting member 44. And a support table 47 (not shown in FIG. 5) supported by the support member 46 and on which the full roll is placed.

In order to support the slider 42 on the frame 18, a block-shaped bracket 48 extending vertically is fixed inside the front end of the frame 18. The bracket 48 has a concave groove 50 (FIG. 6) that opens toward the frame 18 and extends in the front-rear direction of the loom 10. The slider 42 passes through the groove 50 in the front-rear direction. At the bottom of the groove 50 of the bracket, there are provided a pair of ridges 52 which are provided at an interval vertically and extend in the front-rear direction and have a divergent cross-sectional shape. The slider 42 has two grooves 54 into which these protrusions 52 fit. Therefore, the slider 42 can be slid in the front-rear direction along the ridge 52.

A pair of pulleys 56 rotatable about a horizontal axis are mounted between the grooves 54 on the slider 42. The pulleys 56 are spaced from each other in the front-rear direction. A timing belt 58 is hung on both pulleys 56. The lower portion of the timing belt 58 is fixed to the bracket 48 via a fastener 60 near the rear pulley 56. Therefore, when the pulley 56 is driven to rotate, the timing belt 58 does not move, and the pulley 56 in contact with the timing belt 58 moves in the front-rear direction together with the slider 42. 4 and 5
Indicates a state in which the slider 42 has moved to the forefront.

In the illustrated example, a plate-like support member 46 set to have a length shorter than the slider 42 is provided on the inner side portion.
A pair of pulleys 62 are attached at an interval in the front-rear direction. Both pulleys 62 are rotatable about a horizontal axis. A timing belt 64 is attached to both pulleys 62.
Has been passed over.

A single ridge 66 is provided on the inner side of the support member 46 and extends in the longitudinal direction (front-rear direction) and has a divergent cross section. On the other hand, the plate-shaped main body 68 of the support base 47 is provided with a groove 70 into which the ridge 66 is fitted. Therefore, the support base 47 is supported by the support members 46.
Can slide in the front-rear direction. The front end of the groove 70 terminates short of the front end of the support member 46.

The main body 68 of the support base 47 is fixed to the upper part of the timing belt 64. For this reason, when the pulley 62 is driven to rotate, the support table 47 is moved in the front-rear direction together with the timing belt 64.

The support table 47 has a roller 72 for supporting each end of the full roll, that is, each end of the cross roll 14, and a claw member 74. The roller 72 and the claw member 74 are provided with pins 76 and 78 extending in parallel with the full roll.
Is attached to the main body 68 through the through hole so as to be able to rotate and swing. The claw member 74 and the main body 68 are further connected by a spring member 80, and the claw member 74 receives a clockwise spring force as viewed in FIG.

According to this, when the support table 47 is moved below the both ends of the full roll to receive the full roll supported by the loom 10, the upper end of the claw member 74 is moved to the end of the full roll. The pawl member 74 rotates around the pin 78 against the spring force, and the upper end thereof is
Hide in. Therefore, when the support table 47 further moves, it can move relatively until the end portion of the full roll hits the roller 72. At this time, the pawl member 74 returns to rotation due to the spring force, and comes into contact with the peripheral surface of the end portion of the full roll.

By providing the claw 74, the distance in the vertical direction between the main body 68, which can receive the end of the full roll, and the end of the full roll can be reduced.
Accordingly, it is possible to minimize the falling distance of the full roll onto the support table 47 and the impact of the full roll on the support table 47.

The pulley 5 in front of the slider 42
The pulley 6 and the pulley in front of the support member 46 are connected to each other by a shaft member 82 that faces each other and penetrates the connection member 44. A bevel gear 84 is fixed to the shaft member 82. A motor 86 is attached to the connecting member 44, and a bevel gear 88 is fixed to an output shaft of the motor 86. Both bevel gears 84 and 88 mesh with each other inside the connecting member 44.

Therefore, in the state shown in FIG.
Is operated, the shaft member 82 and both pulleys 56 and 62 are rotationally driven via both bevel gears 84 and 88. As a result, the slider 42 advances, and at the same time, the support 47 advances. According to this, the support base 47 substantially moves the forward distance of the slider 42 and the rotation distance of the timing belt 64. Therefore, when these distances are set to be substantially equal, the slider 42 can be moved a distance twice as long as the slider 42 is advanced, whereby the full roll can be moved from the loom 10 more. Can be transported far away.

A new cross roll, which is disposed to replace the full roll after the movement, is held at a position at the front of the loom 10 where the full roll is not disturbed. This new cross roll has the same shape and structure as the above-mentioned cross roll 14, but is denoted by reference numeral 90 for distinction from the cross roll 14.

The cross roll 90 has a pair of guide rails 92 (FIG. 1) which are supported at the front end of the loom 10 at both ends thereof and extend obliquely downward from the front to the rear of the loom.
3) and a beak-shaped stopper member 94 that is in contact with the peripheral surface of the cross roll 90 is prevented from falling along the guide rail 92. The lower end of the guide rail 92 ends diagonally above the extension of the rotation shaft 16, and the cross roll 90 falling from the guide rail 92 is received by the pair of arms 20.

The stopper member 94 is swingably mounted on the shaft 30 to which the arm member 26 supporting the cross roll 24 is fixed. FIG.
As shown in (1), the stopper member 94 has a lower portion that abuts on a rod 96 supported by the frame 18 and extending parallel to the shaft 30, and is prevented from swinging. The stopper member 94 and the rod 96 are connected by a spring member 98, so that the stopper member 94
Is being pulled towards.

Continuing to refer to FIG. 2, the cam member 28 connected to the one arm member 26 has a cylindrical shape as a whole, and a cutout 29 extending in the circumferential direction is provided on a part of the peripheral surface. The base of the stopper member 94 surrounding the shaft 30 is received in the notch 29 and the notch 2
9 can be moved in the circumferential direction relative to 9 and the notch 2
9 are provided with protrusions 94a that can be locked at both ends 29a and 29b in the circumferential direction.

Further, a motor 100 for rotating the shaft 30 and a pair of gears 102 and 10 meshing with each other.
4 are arranged. The motor 100 is supported by one frame 18, and the gear 102 is fixed to an output shaft of the motor 100. The gear 104 is fixed to the shaft 30.

The operation of the motor 100 causes the shaft 30
When the is rotated clockwise, the cam member 28
With the rotation of the shaft 30, the arm members 26 and the press roller 24 swing about the axis of the shaft 30. When the cam member 28 rotates by a predetermined rotation angle, one circumferential end portion 29a of the notch 29 of the cam member hits the protrusion 94a of the stopper member, and when the rotation is further continued, the stopper member 94 Rotated clockwise against force. As a result, the cross roll 90 loses the support by the stopper member 94 and rolls down the guide rail 92.

The cross roll 90 dropped from the guide rail 92 is supported by the loom 10 at a predetermined position and driven to rotate, as described later. Thereafter, a part of the woven fabric 12 is wound around the cross roll 90 by the woven fabric guiding means 106.

As shown in FIG. 7, the woven fabric guiding means 106
Is arranged at the lower part of the front part of the loom 10. The woven fabric guiding means 106 includes a casing 108 for accommodating a cutter for cutting the woven fabric 12 and a moving mechanism thereof, and a wrapping plate 1 of the woven fabric 12 fixed to the casing 108.
10 is provided. The woven fabric guiding means 106 is provided for both frames 1
8, and its wrapping plate 110 is located almost directly below the woven fabric or woven fabric surface 23 wound on the cross roll 14 as viewed in FIG. 1.

The illustrated casing 108 has a substantially rectangular cross-sectional shape, and extends in the weft insertion direction, that is, in the axial direction of the press roller 24. A pair of shaft members 11 penetrating these and extending in the weft insertion direction are provided at both ends of the casing 108.
2, 114 are rotatably mounted. Each shaft member has a slide piece 116 outside the casing 108.
Has been fixed. Each slide piece 116 has a projection 116a which is provided on the bracket 48 fixed to each frame 18 of the loom and engages with a groove 48a (FIGS. 4 and 5) extending in the vertical direction.

A pair of pulleys 118 are arranged inside each bracket 48 at an interval above and below.
8 is mounted rotatably about the weft insertion axis. A timing belt 120 is attached to both upper and lower pulleys 118.
And a motor 122 for rotating the pulley 118 is connected to the lower pulley 118.

Each slide piece 116 is fixed to each timing belt 120 on the side surface of the rear part, whereby the woven fabric guiding means 106 is supported by both timing belts 120. Therefore, the motor 12
When the timing belt 2 is operated, the cloth guiding means 106 moves up and down in accordance with the rotation of the timing belt. At the maximum raised position of the woven cloth guiding means 106, the wrapping plate 110 can be located immediately above the cross roll 90 supported at a predetermined position that is driven to rotate, as described later.

One shaft member 112 has a casing 10
8, a worm wheel 124 is mounted. The worm wheel 124 includes a motor 126
And a worm 128 fixed to the output shaft.
The motor 126 is mounted at the front of the casing 108,
The output shaft extends through the front wall of the casing 108 and into it. When the motor 126 is operated, one of the shaft members 112 is fixed to the timing belt 120 via the slide piece 116, so that the casing 108 rotates around the two shaft members 112. This rotational movement will be further described later.

The casing 108 accommodates a cutter 130 for cutting the woven fabric 12, and is supported by a timing belt 138 described later. The cutter 130 extends in the vertical direction, and its upper part is exposed from a slit 132 formed in the top wall of the casing 108 and extending in the longitudinal direction.

The inside of the casing 108 at intervals in the longitudinal direction, a pair of pulleys 134 which form part of the moving mechanism of mosquito jitter 130 is disposed. One pulley 134 on the worm wheel 128 side is connected to the casing 108.
It is rotatably supported on the rear wall of the vehicle. The other pulley 1
Reference numeral 34 is attached to the output shaft of the motor 136. The motor 136 is opposed to the motor 126,
08 is mounted on the front wall at the other end. A timing belt 138 is stretched over both pulleys 134,
The lower end of the cutter 130 is fixed to the upper part of the timing belt 138. According to this, the motor 136
By operating the cutter 130, the cutter 130 is
2, the woven fabric 12 that crosses the slit 132 can be cut during the linear movement.

The wrapping plate 110 fixed to the casing 108 has an L-shaped cross section, extends rearward from the casing 108, and has its tip bent downward. A pair of pipes 138 and 140 are attached to the winding plate 110 along the inwardly bent portion and the connection between the winding plate 110 and the casing 108, respectively. The pipes 138, 140 are provided with a plurality of nozzles 138a, 138b, 140a (FIG. 19), respectively. Fluids consisting of compressed air or pressurized water are supplied to the pipes 138 and 140, respectively.
It is ejected from the nozzles 138a, 138b, 140a.
As shown in FIG. 19, the nozzle 138 provided in the pipe 138
a and 138b are directed downward and to the right, respectively, and the nozzle 140a provided in the pipe 140 is directed downward and to the right. The nozzle 138b penetrates a bent portion of the winding plate 110.

Next, the operation of replacing the cross roll in the loom 10 will be described. The loom 10 is a woven cloth 1 having a predetermined length.
When it is detected that 2 has been wound on the cross roll 14, the control device (not shown) of the loom 10 outputs a cross roll exchange signal. The operation of the loom 10 is continued.

When this exchange signal is output, both rotating shafts 1
6 retreats in its axial direction and leaves the cross roll 14. As a result, the cross roll 14, ie, the full roll, obtained by winding the woven cloth of a predetermined length loses support and falls a small distance, and a pair of support bases which have been moved directly under these at both ends of the full roll in advance. It is received by 47.
The press roller 24 receives the tension of the woven fabric 12 and
3 is in contact. Prior to the retraction of the rotating shaft 16, it is desirable to temporarily stop the rotation of the full roll or to reverse the full roll by a predetermined amount to temporarily reduce the tension of the woven fabric 12.

The press roller 24 swings counterclockwise as the diameter of the woven fabric surface 23 increases, and the cam member 28 (see FIG. 2) rotates accordingly. As a result, in the state shown in FIG. 8, the other circumferential end portion 29 b of the cutout of the cam member 28 is immediately before contact with the projection 94 a on the base of the stopper member 94.

Next, as shown in FIG. 9, the motor 86 (FIG. 5) of the moving means 40 is operated, thereby
To move the full roll forward of the loom 10. Preferably, the motor 100 (FIG. 2) is simultaneously operated to swing the press roller 24 clockwise. This makes it possible to reduce the zigzag movement of the full roll based on the unequal speed of both support tables 47. Since the tension of the woven fabric 12 is temporarily reduced, the rotation of the full roll based on the tension of the woven fabric can be prevented when the rotating shaft 16 is retracted in the axial direction and when the full roll is advanced. Thus, it is possible to prevent the full roll from rolling off the support table 47.

As the press roller 24 swings clockwise, one end 29a (FIG. 2) of the notch of the cam member 28 comes into contact with the protrusion 94a of the stopper member, and the stopper member 94 is moved clockwise. Rotate. As a result, the contact of the stopper member 94 with the cross roll 90 is released, and the cross roll 90 rolls along the guide rail 92.
At this time, the press roller 24 is swung clockwise, and since the two arm members 26 that support it cross the two guide rails 92, the cross roll 90 hits the two arm members 26 and stops rolling. .

Next, as shown in FIG. 10, the arms 20 are then swung clockwise to position the hook portion 20b substantially at the level above the rotary shaft 16.

Next, as shown in FIG. 11, the cross roll 90 on the guide rail 92 is further rolled and lowered, and the press roller 24 is swung counterclockwise so as to be received by both arms 20. Accordingly, tension is applied to the woven fabric 12, and the stopper member 94 is
Due to the spring force of FIG. 2, it rotates counterclockwise around the shaft 30 until it hits the rod 96.

Next, as shown in FIG. 12, both arms 20 are slightly swung counterclockwise so that the cross roll 90 is positioned on the extension of both rotating shafts 16.

Next, as shown in FIG. 13, the both rotating shafts 16 (see FIG. 11) during the rotating motion are advanced toward both ends of the cross roll 90, and the two projections 16a and the annular projections 16b (see FIG. 9) is fitted into the groove 14a and the hole 14b (FIG. 1) of the cross roll 14. As a result, the cross roll 90 is supported by the rotating shafts 16 and driven to rotate.
Then, both arms 20 are connected to these hook portions 20b.
When the full roll is formed, it is swung counterclockwise to an original position where it does not contact the peripheral surface. In the state shown in FIG. 13, there is an interval between the cross roll 90 supported by the loom 10 and the press roller 24.

Next, as shown in FIG.
2 (FIG. 7) is actuated to raise the woven cloth guiding means 106 to a position substantially below the moving means 40.

Next, as shown in FIG.
(FIG. 7) is operated to rotate the cloth guiding means 106 counterclockwise by 90 degrees. As a result, the bent portion of the winding plate 110 lifts the woven fabric 12 extending from the full roll.

Next, as shown in FIG.
2 (FIG. 7) is operated to further raise the cloth guiding means 106. As a result, the wrapping plate 110 further raises the woven fabric 12, and the woven fabric 12 bends in a chevron. As shown in FIG. 17, when the woven cloth guide means 106 is rotated 90 degrees clockwise, the winding plate 110 covers a part of the cross roll 90 from above. Is a height position where

As shown in FIG. 17, when the wrapping plate 110 rotates 90 degrees clockwise, a part of the woven fabric 12 is wrapped around the upper peripheral surface of the cross roll 90 below the wrapping plate 110. At this time, the winding plate 11
A portion of the woven fabric 12 extending above the zero crosses the housing slit 132 (FIG. 7), which is the path of the cutter 130.

The cross roll 14 constituting the full roll on the support table 47 receives the moving force toward the roller 72 (FIG. 4) when the woven fabric 12 is pulled rightward in the drawing, and comes into contact with the roller 72. Rotates counterclockwise in between. From this, FIG.
In the process shown in FIG. 6 and FIG. 17, the wrapping plate 110 applies a tensile force to the woven fabric 12, the cross roll 14 rotates counterclockwise, and the woven fabric 12 is pulled out from the full roll.

Next, as shown in FIGS. 18 and 19,
The cutter 130 is moved along the slit 132 by operating the motor 136 (FIG. 7). As a result, slit 1
The woven fabric 12 across the 32 is cut. With the start of cutting the woven fabric 12 by the cutter 130, the nozzles 138a, 1
The fluid is ejected from 38b and 140a. The jetting fluid presses a part 12a of the woven fabric extending along the upper part of the cross roll 90 rotating clockwise against the peripheral surface of the cross roll. Also, a cut end having a warp caused by cutting
That is, the free end (hereinafter, simply referred to as “end”) 12b of the woven fabric including the free end receives the pressure of the jet fluid (water or air) from the nozzle 138b in the horizontal direction, and the wrapping plate 110 It moves upward to the side of the press roller 24 and finally reaches a space 142 between the press roller 24 and the cross roll 90.

Referring to FIGS. 20 and 21, when the end 12b of the woven fabric is guided into the space 142, the fluid injection is stopped. Next, the motor 100 (FIG. 2) is operated, whereby the press roller 24 is swung clockwise to abut the press roll 90. As a result, in the illustrated example, the end 12b of the woven fabric in the space 142 has a V-shape and its tip is in contact with the peripheral surface of the press roller 24, so that the end 12b of the woven fabric is folded in two. In this state, it is sandwiched between the cross roll 90 and the press roller 24.

As a result of swinging the press roller 24 in the clockwise direction, a part 12 c of the woven cloth that goes around the press roller 24 and reaches the lower peripheral surface of the cross roll 90 sags and hangs down. As a result, the frictional force between the press roller 24 and the woven fabric 12 is sharply reduced, the press roller 24 is driven to rotate by the cross roll 90, and the end of the woven fabric sandwiched between the press roller 24 and the cross roll 90 is rotated. The part 12b receives a feed force.
At this time, since the cross roll 90 is substantially in a no-load state, the peripheral speed of the cross roll 90 is higher than the moving speed (weaving speed) of the woven fabric 12. For this reason, the end 12b of the woven fabric is quickly and reliably guided between the cross roll 90 and the portion 12c of the woven fabric, and the cross roll 90 is moved until the slack of the portion 12c of the woven fabric is eliminated. At this time, no winding wrinkles occur. When the slack of the portion 12c of the woven fabric is eliminated, the woven fabric 12 and
4, a large frictional force acts, and the driven rotation of the press roller 24 stops.

Next, referring to FIG. 22, the woven fabric guiding means 106 in the state shown in FIG. 21 is rotated counterclockwise by 90 degrees, then lowered, and further rotated clockwise by 90 degrees, whereby the original cloth is rotated. To the position. At this time,
The operation of the motor 100 (FIG. 2) for oscillating the press roller 24 is stopped, and the press roller 24 oscillates by its own weight, and the woven fabric 12 wound on the cross roll 90 is adjusted to the tension of the woven fabric. Pressing with the applied force prevents the occurrence of wrinkles.

Next, as shown in FIG. 23, a new cross roll 144 is supplied on the guide rail 92, and
It is held on the guide rail 92 by the stopper member 94. At this time, the full roll is carried away from the loom 10. The press roller 24 swings counterclockwise as the winding diameter of the woven fabric 12 increases. During this time, the other end 2 of the notch of the cam member 28 until the winding diameter becomes a predetermined size.
9 b (FIG. 2) rotates to the position immediately near the protrusion 94.

Next, the support table 47 of the full roll moving means 40
Is moved backward until it is directly below the cross roll 90. During the movement, the claw member 74 (FIG. 4) of the support base 47 is
When it hits the peripheral surface (woven cloth surface) of the cross roll 90, it rotates counterclockwise against the spring force of the spring member 80, and its upper end is hidden in the main body 68 that supports it, and the support table 47 is smoothly moved. Go to The pawl member 74 can be swung in this way,
As a result of the upper end being hidden in the main body 68 by the swing, the distance in the vertical direction between the cross roll 90 and the support table 47 directly below the cross roll 90 can be reduced, and as a result, Impact when the cross roll 90 is dropped can be minimized.

The woven cloth guiding means may be any means capable of guiding the end 12b of the woven cloth between the cross roll 90 and the press roller 24. For example, Japanese Patent Application Laid-Open
A woven cloth guide device having a claw-shaped tip portion provided in an interloom movable cross roll exchange device disclosed in Japanese Patent No. 3353 can be applied. The woven fabric guiding device retracts after guiding the end of the woven fabric between the cross roll and the press roll, and at the same time, advances the press roller toward the cross roll.
