Abstract
A method for cutting a mat of plies of fabric in order to facilitate the removal of stacks of cut pattern pieces, which consists of the fact that in addition to perimetrically cutting the contours of the various pattern pieces, additional cuts are formed in the mat which connect the various contours to each other and to the edges of the mat, the cuts reducing the residues of the mat to small and mutually separate portions. The machine for automatically removing the stacks from a cutting table has a supporting framework which is provided with elements for fixing to the table; a conveyor belt for removing the pieces, which is arranged at the base of the framework directly to the side of the table; grippers for gripping and releasing the stacks which are associated with movement elements for producing lifting and lowering and translatory motion along a direction which is parallel to the belt, the movement elements being controlled by a central control and actuation unit which can be programmed according to the shape and arrangement of the stacks in the mat.
