PROCESS FOR THE SEALING OF PLASTIC PROFILED ELEMENTS
FIG1 is an axonometric view of a machine for the sealing of plastic profiled elements
As can be seen in FIG1, the machinery 1 is equipped with a containment presser 13, but it cannot be ruled out that two containment pressers 13 be arranged facing one another and both moveable in reciprocal approach to abut on opposite sides of the areas to be sealed 3.

['1. A process for the sealing of plastic profiled elements, comprising: - at least one step of supply of at least a machinery (1) for the sealing of plastic profiled elements comprising: - at least a base frame (2); - retaining means (6, 7) associated with said base frame (2) and adapted to retain at least one profiled element (P) having at least one area to be sealed (3) and a lateral surface (4) at least in part covered with a film (S) to be removed; - sliding means (8, 9) adapted to move said retaining means (6, 7) between a mutual spacing configuration, in which said areas to be sealed (3) are mutually spaced apart, and a mutual approach configuration, in which said areas to be sealed (3) are mutually approached; - heat-sealing means with a heated plate (5) associated with said base frame (2) and adapted to seal said pair of profiled elements (P); - at least one step of mutual movement of said retaining means (6, 7) adapted to arrange the areas to be sealed (3) of each of said profiled elements (P) facing each other; - at least one step of arrangement of said heat-sealing means with a heated plate (5) in contact with said areas to be sealed (3); - at least one step of sealing said areas to be sealed (3); characterized by  the fact that it comprises at least a step of heat shrinking of at least an ending portion (14) of each of said films (S) arranged at the respective area to be sealed (3), said film (S) being made of a heat-shrink material.']
