Tracing element fixed on leather punch - triangular flexible sheet having pins fixed in its base and in punch

摘要

The system is for a rapid application of tracing elements on a punching machine (4) used in the manufacture of shoes, or leather goods. It uses a flexible sheet (1), made of polyvinyl chloride, or other suitable material, that is an isosceles triangle in transversal section. The lower part of this has a series of holes, very close to each other and in its transversal plant of symmetry. The holes each have an inner wide spherical cavity and pins with two spherical extremities fit into this and in the internal structure of the punching machine.
