PL429577A1 - Device for cutting holes in leather or imitation leather belts - Google Patents

Abstract

In one of the solutions, the device for cutting holes in leather or leather-like strips is characterized by the fact that its lower adjusting subassembly is a plate support base (2) having parallel graduations (26) on its upper surface, four blind holes and made along the axis its symmetry, a threaded hole into which the insert is screwed in and two identical profile shoulders (14) located in the horizontal axis of symmetry of this insert with threaded holes made in them, and rectangular recesses (18) are made on both sides of the profile shoulders (14), the lower shoulders of the rails (20) located perpendicular to these recesses are slidably mounted, while the rails (20) are equipped with measuring scales (21) and side shoulders (22) with through holes (23) made in them for threadless ends (24) ) of the bolts (16), while the upper pressure sub-assembly (6) is made of a plate (5) made of PMMA type plastic, which in the axis of symmetry has a finished through threaded hole into which a metal body (29) is screwed with a sleeve punch with a lower oblique blade, the subassemblies connected with each other by two pairs of cylindrical guides (3) with springs (4) placed on them, the lower ones the ends of these guides are embedded in blind holes made in the plate support base (2), and their upper ends are seated in the through holes in the plate (5) of the upper pressure sub-assembly.
