A number of elements 27 move up and down via the air cylinder 35 in accordance with a predetermined pattern on the floppy disk 42.

As shown in FIG. 2, in the element 27 at the lower movement position A, since the space between the upper end of the thick head 29 and the spiral cutter 1 is large, the pile 5 corresponds to the hatched portion a in FIG. The pile 5 is sheared so as to have a longer length, and the gap between the upper end of the thick head 29 and the spiral cutter 1 becomes smaller in the element 27 at the upper movement position B. The pile is correspondingly sheared to reduce the length.

Since a large number of elements 27... Densely arranged over the entire length of the above-mentioned spiral cutter 1 in the axial direction move up and down in accordance with a set pattern via the solenoid valve 44 and the air cylinder 35, the pile fabric 6 has the structure shown in FIG.

Each of the elements 27 is formed in a stepped structure in which the thickness of the thick head 29 and the thickness of the thin main body 28 are different, and the legs 30 of the adjacent elements 27 are offset from each other. Since the piston rod 36 of the air cylinder 35 is disposed so as to face each of the legs 30, the air cylinder 35 has a cylinder tube outer diameter that does not interfere with each other. The cylinder 35 can be arranged, and the thick head 29 of the element 27 can be densely arranged at zero intervals over the entire length of the spiral cutter 1 in the axial center direction.

As a result, since there is no space between the adjacent thick heads 29 as in the prior art, a fine pattern can be obtained.

In addition, the movable element cover 13 can be adjusted up and down by the above-mentioned first elevating means 14, so that when the pile fabric 6 having a long pile length, such as a blanket, is sheared, the elevating table 8 is used for shearing. The entire table 3 is slightly lowered, and the movable element cover 13 is moved upward by the above-described first elevating means 14, so that the first interval g
When 1 is set to a large value, the element 27 protrudes by an amount corresponding to the first interval g1, so that cutting corresponding to the pile fabric 6 having a long pile length can be performed.

When the pile fabric 6 having a short pile length, such as a car seat, is sheared, the whole of the shearing table 3 is slightly raised by the lift 8 and the movable element cover 13 is lowered by the first lifting means 14. Let me move
When the first interval g1 is set to be small, the element 27 protrudes by an amount corresponding to the first interval g1, so that trimming corresponding to the pile fabric 6 having a short pile length can be performed. Thus, regardless of the length of the pile length, there is an effect that the shearing process corresponding to all the pile fabrics 6 can be performed by one shearing device.

The movable element cover 13 is moved up and down by the first elevating means 14 to an arbitrary position by, for example, operating a push button switch while visually observing a display device visually displayed by a signal from the digital scale 37. Can be set.
