First, in the state shown in FIG. 5, a plain weave portion 1b of towel cloth is placed on the receiving piece 31 in advance. In this state, the holding mechanism 39 is driven by the driving device 40 of the main drawer 35.
Is moved to the gripping position as shown in FIG.
44 to open and close the tip of the gripping piece 42,
Thus, the tip of the plain weave portion 1b of the towel cloth 1 is sandwiched.
Then, in that state, as shown in FIG.
39 is retracted to the extraction position. In this process, in the aligning device 4, in the aligning device 4, the advancing / retreating frame 15 is advanced by the advancing / retreating means 15 so that the alignment body 11 is positioned above the receiving piece 31 as shown, and the hook 23b is located immediately above the fixed blade 28a. It is better to keep it in the position. Next, as shown in FIG. 7, the piston rod 16b of the support member 16 is extended downward to lower the alignment body 11, and
As shown in the figure, the hooks 23b of the large number of hooks 23 are brought into contact with the upper surface of the towel cloth 1, respectively. In this case, the support piece 22b and the take-out piece 23a are slightly bent from the natural state shown by the imaginary line to the state shown by the solid line against the respective spring forces. Further, in this case, when the support piece 22b and the take-out piece 23a bend against the spring force as described above, the recumbent rod 21 receives the upward reaction force R by the spring force. Accordingly, the reaction force R and the downward thrust T of the piston rod 16b in the cylinder 16 are balanced. For this purpose, it is preferable to use an air cylinder as the cylinder 16. In the above state, the elastic pressing mechanism 58 is lowered by the cylinder 51 as shown in FIG. By this lowering, the towel cloth on the receiving piece 31 is further pulled out in the direction of the arrow. Then, as shown in FIG. 11, when the cast portion 1c arrives below the hook claw 23b of the hook piece 23 in the aligned body 11, the hook claw 23b fits into the cast portion 1c and is attached to the cast portion 1c. It is hooked on the tip of the following plain weave 1b. Thereby, the movement of the towel cloth 1 is prevented in that portion. In this case, if the cast portion 1c is neatly aligned on a straight line perpendicular to the moving direction of the towel cloth 1, all the hooking claws 23
b fits into the cast 1c almost at the same time. But thirteenth
If the caster portion 1c is curved or oblique to the traveling direction of the towel cloth 1 as shown in FIG.
As shown in FIG. 11, only a part of the hooking claw 23b fits into the cast portion 1c, and the other hooking claw 23b does not fit. Therefore, in places where the hooking claw 23b has not yet been fitted into the cast portion 1c in each portion in the width direction of the towel cloth, the movement of the towel cloth 1 is further continued. That is, since the elastic pressing mechanism 58 is continuously lowered, the towel cloth 1 is further pulled out at the portion where the hooking claw 23b has not yet been fitted into the cast part 1c in each section in the width direction of the towel cloth 1. It is performed continuously. On the other hand, in a place where the hook claw 23b has already been fitted into the cast part 1c, even when the movable frame 61 is lowered in the case of the lowering of the elastic pressing mechanism 58, the leaf spring 64 is largely bent and the towel cloth 1 is appropriately In this case, excessive pulling is prevented. As described above, the locking claws 23b of all the locking pieces 23 in the aligned body 11 will be
As shown in the figure, when fitted into the cast portion 1c, the cast portion 1c
Are aligned in a direction perpendicular to the traveling direction of the towel cloth. At this time, the reaction force (upward reaction force) given to the recumbent rod 21 by the spring force of the support piece 22b and the take-out piece 23a is weakened, so that the thrust of the piston rod 16b exceeds it, and The rod 21 is further lowered to a predetermined position as shown. Due to this lowering, the operating piece 25 of the alignment completion detecting device 12 activates the switch 24,
The signal from 24 gives confirmation that the alignment is complete. When the alignment is completed as described above, the holding piece 33 is lowered by the cylinder 32 as shown in FIG.
The towel cloth 1 is clamped between the holding piece 33 and the pressing piece 33. Further, the cylinder 30 is contracted and the cylinder 32 is extended while keeping the clamped state, and the receiving piece 31 is lowered as shown in FIG. Next, the alignment body 11 is raised by the cylinder 16. In this case, since the cast portion of the long towel cloth pulled on the side of the drawing device is clamped by the pressing piece 33, the aligned state is maintained. Further, the advance / retreat frame 14 is moved backward by the cylinder 15 as shown in FIG. Further, the known holding piece 69 is lowered onto the towel cloth 1 above the guide rail 67, and the elastic pressing mechanism 58 is raised. Next, the movable blade 28b is lowered by the cylinder 29, and the cast portion 1c of the towel cloth 1 is cut by the fixed blade 28a. Next, by moving the pressing piece 69 along the rail 67 in the direction of arrow 68 in FIG. 1, the cut towel cloth piece 1A is carried to the next step. Simultaneously with or after this, the movable blade 28
b, the receiving piece 31, the holding piece 33 and the like are raised as shown in FIG. Thereafter, the above operation is repeated to perform the long towel cloth 1
Cut many towel cloth pieces 1A one after another. (Effect of the Invention) As described above, in the present invention, the cast portion 1c of the long towel cloth 1 pulled out by the pulling-out device 6 is pulled toward the drawing-out device side, and the alignment device 3 is used. There is a feature that the caster portion 1c is aligned so as to be perpendicular to the longitudinal direction of the towel cloth, and can be cut by the cutting device 5. Moreover, when the cutting is performed, the retaining piece 23 of the aligning device used for the alignment is retracted from the cast portion 1C prior to the cutting. The state after the alignment of the cast portion 1C of the towel cloth 1 is characterized in that the clamp device 27 is maintained against its tensile force. This is because, for example, when the caster portion 1C is extremely narrow, the blade of the cutting device main body 26 is exchangedly inserted even at the position of the caster portion where the hooking piece 23 has been inserted. Make it possible to cut off parts. That is, even if the cast portion 1C is narrow, the cast portion position is always aligned, and the intermediate position there is accurately cut, so that the size of the cast portion in the cut towel cloth is constant, and a towel called good quality It has the effect of providing fabric.
