That is, a rotary roll 93 is integrally formed with a ridge 92 for obtaining a predetermined pattern on the surface of the roll body 91, and the rotary roll 93 is disposed below the spiral cutter 94.
When a pile fabric 97 in which a large number of piles 96 are formed on the base cloth 95 is conveyed in the direction of the arrow in FIG. 14 by a conveying device (not shown), the pile 96 tip is between the spiral cutter 94 and the lower blade 98. A shearing device configured to shear a part.

According to this conventional apparatus, the pile 96 corresponding to the above-mentioned convex strip 92 is sheared short and the pile 96 corresponding to the roll main body 91 is sheared long, so that there is an advantage that a predetermined pattern can be obtained. On the other hand, the shape of the ridges 92 of the rotary roll 93 only provides a constant repetitive pattern, and in order to reveal another pattern, another rotary roll having a different ridge 92 is required. However, there was a problem that only a simple repeating pattern could be obtained.

In order to solve such a problem, the present applicants have already invented the shirring device described in JP-A-60-75662. That is, a large number of elements whose protrusions are individually controlled by the piston rods of the air cylinder are arranged so as to be movable up and down with respect to the element block, and air is supplied to the air cylinder via the control device by a signal from the handle reading device. By controlling the stop,
A shirring device configured to obtain various patterns.

However, in this conventional device, the outer diameter of the air cylinder tube of the air cylinder for individually operating the above-mentioned elements is regulated, and a space is necessarily formed between the above-mentioned elements. However, there is a problem that it is difficult to obtain a fine pattern even though a coarse pattern can be obtained.

In addition, since the movable element cover 13 can be vertically adjusted by the above-mentioned first elevating means 14, when the pile fabric 6 having a long pile length such as a blanket is sheared, it is sheared by the elevating table 8. The table 3 as a whole is slightly lowered, and the movable element cover 13 is moved upward by the above-described first elevating means 14 to move the first gap g.
When 1 is set to a large value, the element 27 protrudes by an amount corresponding to the first gap g1 so that the pile fabric 6 having a long pile length can be trimmed.

When the pile fabric 6 having a short pile length such as a car seat is sheared, the lifting table 8 raises the entire shearing table 3 slightly, and the first lifting means 14 lowers the movable element cover 13. Move
When the first gap g1 is set to a small value, the element 27 projects by an amount corresponding to the first gap g1, so that the pile fabric 6 having a short pile length can be trimmed. In this way, regardless of the length of the pile, it is possible to perform shearing processing corresponding to all the pile fabrics 6 with one shearing device.
