ABSTRACT:
The invention relates to a process and an equipment to obtain a plate provided with holes directly by extruding plastic materials. The process consists in submitting the material coming out of an extruder head to expansion stresses according to more than one direction and in executing a plurality of perforations in said material submitted to expansion by means of perforating means; the equipment consists of a plurality of perforating devices provided with a reciprocating motion so that they can reach an interference position with respect to the material coming out of the extruder head and of means which, acting at the same time as the perforating devices, are suitable to produce an expansion of the extruded material.
