Abstract

Process for the realization of counter-mould elements for the containment of welding bead of plastic profiled elements, in which counter-mould elements (1) have a main body (2) adapted to receive in abutment a pair of profiled elements of plastic material welded together to obtain a frame for windows/doors, each profiled element comprising a welding surface weldable to the welding surface of another profiled element in a welding configuration in which the lateral faces of profiled elements are substantially adjacent to one another and define a locator surface, wherein the process comprises: a phase of acquisition of the profile of a portion of the lateral faces; a phase of definition of the profile of a contact surface (3) of the main body (2) adapted to receive in abutment the locator surface, the profile of the contact surface (3) being substantially complementary to the profile of the locator surface; a phase of three-dimensional molding obtained by means of a three-dimensional molding device (4) to obtain the main body (2) starting from the profile of the contact surface (3) obtained in the phase of definition.

Dependent claims

A process for a realization of a counter-mould elements of a machine for welding plastic profiled elements for windows/doors frames, comprising:

at least one phase of acquisition of a profile of at least one portion of lateral faces of a pair of plastic profiled elements to be welded together, each profiled element comprising at least one welding surface weldable to a welding surface of another profiled element, where said lateral faces of said profiled elements welded together are substantially adjacent to each other;
at least one phase of definition of a profile of at least one contact surface (3) of a counter-mold element (1), adapted to receive in abutment spa locator surface defined by said lateral faces substantially adjacent to each other of said profiled elements welded together, said profile of said contact surface (3) being substantially complementary to a profile of said locator surface;
at least one phase of three-dimensional molding wherein at least one three-dimensional molding device (4) is used to obtain a main body (2) of said counter-mold element (1), provided with said contact surface (3), starting from said profile of said contact surface (3) obtained in said phase of definition.
