Automatic hollow punch search method for die-cutting machines, particularly for footwear production

摘要

Method for operating an automatic hollow punch search device and relevant control, for die-cutting machines, particularly for footwear production, in which a mobile head is associated to a device to move it to and fro, both horizontally and vertically, above a fixed faceplate on which the material to be cut is placed, together with a hollow cutting punch. The movement devices are automatically piloted by a drive circuit interlocked to manual starting device which provides means to carry out a complete head movement operating sequence from its positioning above the hollow punch to its lowering and return to the starting point after cutting.
