Abstract

Procedure for manufacturing networks and structures that have a reticulated shape, and in particular for manufacturing laminar structures made of thermoplastic synthetic material comprising ribs arranged in the form of a network as well as through openings, which is fundamentally characterized by the fact that according to it, part of a band or laminar strip of thermoplastic synthetic material endowed with contraction capacity and formed by one or several superimposed layers, first proceeding to practice on said band a plurality of grooves or grooves which are arranged oriented in a direction substantially transverse to the direction of shrink are placed in mutually parallel rows and in such a way that those of one row are displaced with respect to those of the adjacent rows, being partially juxtaposed at their ends, then proceeding to subject said band to the action of heat without externally exercising on it considerable transverse traction with respect to the direction of the grooves or grooves, so that the thermoplastic material softens and the portions that are between said grooves or grooves undergo transverse contraction, which simultaneously causes their permanent opening, further highlighting the fact that the shrinkage capacity of the starting material, which may even be thermoplastic foam material, is preferably achieved by prior stretching carried out at least in one direction that is the same desired contraction direction, also highlighting the particularity of that in order to dispose of the strip or strip that serves as a starting material in the cases in which it is desired that it be made up of several layers, the same or different sheets can be superimposed, or flat or composite tube sheets can be flattened, or You can even combine the two possibilities previously referred you give, so that in all such cases a single combined body will be obtained after joint contraction.
