摘要:
The method for welding profiled elements in plastic material, in particular PVC, comprises the steps of: - preparing two profiled elements (3; 3a, 3b; 60, 61), arranged with respective zones to be welded (4; 62, 63) facing one another; - making a groove (19) in correspondence to at least one zone to be welded (4; 62, 63) of the profiled elements (3; 3a, 3b; 60, 61), the step of making the groove (19) being performed by means of a removal operation on a peripheral edge of at least one profiled element (3; 3a, 3b; 60, 61); - heating the zones to be welded (4; 62, 63); - coupling the zones to be welded (4; 62, 63) to one another, pressing the profiled elements (3; 3a, 3b; 60, 61) one against the other so as to keep the zones to be welded (4; 62, 63) in reciprocal contact; - the step of coupling the zones to be welded (4; 62, 63) comprising: - a sub-step of melting the zones to be welded (4; 62, 63) into one another in order to define a welding bead; - a sub-step of making a containing compartment (19a) defined by the groove (19), the welding bead being made internally of the containing compartment (19a); and - the step of arranging a containing presser (27) in correspondence to the containing compartment (19a) for preventing exit of the welding bead from the compartment itself.

A process for the manufacture of windows/ doors, characterized by the fact that it comprises the following steps: • - providing at least one inner panel for windows/doors; • - providing a plurality of plastic profiled elements (3) for windows/ doors, each of the profiled elements (3) comprising at least two areas to seal (5), coupleable to the areas to seal (5) of the other profiled elements (3), and at least one longitudinal slot (6), in which a respective perimeter side of the inner panel is insertable; • - performing a step of mechanical machining by chip removal on at least one of the areas to seal (5); • - heating the areas to seal (5); • - coupling the heated areas to seal (5) to one another by pressing the profiled elements (3) one against the other to maintain the areas to seal (5) in mutual contact and define the frame for windows/doors, the coupling taking place with the inner panel inserted in the longitudinal slots (6) to define a window/door which is composed by the frame and by the inner panel contained in the frame. A system for implementing this process is also disclosed.
