TITLE: "PLANE DIE-CUTTING MACHINE" INVENTOR: Mr. Angelo BARTESACHI, an Italian citizen, residing at Via Caduti a Fossoli 22, LECCO, Como, Italy ABSTRACT OF THE DISCLOSURE The invention concerns a plane die-cutting machine for die-cutting laminar material, of the type comprising a plane punch and an arc-shaped counter punch, which is controlled by moving mean pressing the same against a work material inserted between it and the punch, said counter punch being simultaneously rotated around a li- ne of instant-contact which runs along the punch. To avoid impacts between the reciprocally moving parts, the invention provides extensions integral to the punch and to the counter-punch, which maintain the contact between these latter for a portion of the reciprocal oscillatory movement outside the die-cutting area, so that said reci- procal oscillatory movement takes place with constantly contacting zones, like a blotter of blotting-paper. The die-cutting area is defined in such a way that, when the reciprocally moving parts contact themselves at the ends of said extensions, between the die-cutting parts a hollow space is left, which is sufficient for the passa- ge of the laminar material under work. - - - -
