Abstract: A control device for the driving and translation, in a chosen direction, of the movable head of a diecutter machine, provides for the pre-setting of the direction of translation and for the successive driving of the pressing head by means of five sets of sensitive plates switches, disposed in the front portion of the machine. By touching opportunely one or two of said plates, combinative logic circuits are activated that allow selection of the direction of motion, the actuation of the thus preset displacement and the lowering of the head for the cutting operation.

Abstract: 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.

Abstract: Fast head operating device for flag type die-cutting machines, comprising a hydraulic circuit with one end connected to a feed pump and the other to two cylindrical chambers defined at the base of a column supporting the head of the die-cutting machine, the hydraulic circuit comprising a control valve, equipped with a seal which slides into and is engaged in the body of the same valve to form a fluid communication between a feed conduit and a first inlet conduit, which flows into one of said cylindrical chambers for the rise of the column and with a second inlet conduit which flows into the other cylindrical chamber for the downstroke of the abovementioned column. Interposed on said first inlet conduit, a sequence valve is provided while a further fluid conduit branching from the second inlet conduit, flows into a cylindrical chamber into which a small piston slides and is engaged, carrying, at the opposite end, the mobile contact of a pressure switch connected to the electric operating device.
