In addition, a fixing means 340 is formed at the rear end of the table 310 so that when the transfer means 320 is retracted to its original position, the processing fabric 120 is pressed in close contact with the table 310 so as to prevent pushing. , When the transfer means 320 moves forward, it may serve to release the fixed state.

The fixing means 340 forms a support 341 for supporting the lower part of the processed fabric 120 as shown in FIG. 7, and is supported by pressing the upper part of the processed fabric 120 on the upper part of the support 341 A pressure flat 343 to be compressed to the flat 341 may be formed, and a pressure device 345 may be formed to provide an operating force for the pressure flat 343 to move up and down.

In addition, the fixing means 340 as shown in Figure 10

After forming a support 341 supporting the lower portion of the processing fabric 120, forming a bracket 347 standing perpendicular to both ends of the support 341, it is hinged to the upper end of the bracket 347 It is possible to form a rotation gate 348 to open or close the lower end.

The rotation gate 348 is installed in a form in which the left end of the moving direction of the fabric contacts the upper surface of the processing fabric and the support 341 when the rotation axis is centered.

Such a rotating gate 348 is opened when the processing fabric advances toward the punch processing unit 200, whereas when the transfer means 320 retreats, that is, the processing fabric 120 moves backward toward the material supply unit 100. When a force is applied, the gate is closed and the processing fabric 120 is pressed between the support 341 and the processing fabric 120 is prevented from being pushed.
