According to the present invention, the fabrics to be transported are laminated at the same time as cutting, and when the fabrics are stacked by a predetermined quantity, the stacking positions are also changed by changing the set number of times. .

In addition, by implementing the division theorem by the number of units of fabric through the minimum operation, it is possible to minimize the power consumption and wear and stress of the components (machine parts).

In addition, the present invention can be solved the problem that the operation of changing the lamination position of the fabric is made through a partial rotational movement around the rotation axis, if there is a foreign matter in the slide support path, such as a slide method, malfunction or breakage of the slide support path.
