摘要

Method and device for closing a flexible thermoplastic material embossing by welding, a method characterized in that it comprises the phases of crushing the embouchure in the area to be welded, in order to give its wall the configuration of two walls joined and joined by two flat folds oriented perpendicularly to the general direction of the embouchure in the area to be welded, to give to its wall the configuration of two joined walls and joined by two flat folds oriented perpendicular to the general direction of the embouchure in the area, applying the two walls one against the other. Work under pressure in the area, encourage the two walls of an alternating relative movement in the area in question keeping the assembled under pressure, to cause a warming of their confronting faces in the area and their localized fusion, and then interrupt the movement and cause welding of the melted zones by cooling them.
