Estimating the term…
Specially designed to form an element that is easy and fast to install, with a long useful life and which improves the expulsion of residues after stamping, the counter-die of the invention is composed of a tubular body, divided into several parts (1-1′-1″) and joined to each other by tongue and groove joints using twisted edges (2) at the ends, preferentially three parts, these having an inner sector (3) which is the largest, of injected plastic, very resistant and light, over the exterior surface of which there is a coating (4) of polyurethane. The parts are joined to each other by orifices and grooves in their ends, more specifically in the area made of injected plastic, through which the respective rods or pins (11) pass.
A counter-die for the cylinders of rotary die-cutting machines, of the type used to cover the cylinder on which the die acts, with the aim of preventing deterioration of the blades of the latter, characterized by the fact that it is composed of a tubular body, divided into several parts (1-1′-1″) that may be fitted together using tongue and groove joints, preferentially in sets of three, these parts having an inner sector (3) and which is larger, usually of injected plastic, on the exterior face of which it is coated (4) in polyurethane, while the parts include the means of quickly interconnecting them.
