Abstract

La presente invención se refiere a un método para termoformar objetos huecos, el cual incluye: extruir un tejido de material termoplástico directamente en un juego de rodillos templadores de temperatura controlada, enfriar las capas superficiales superior e inferior del tejido mediante el pasaje a través de dichos rodillos templadores mientras se mantiene el interior del tejido en una condición fundida entre dichas capas superficiales, alimentar el tejido parcialmente enfriado sobre una banda transportadora, y transportar el tejido hasta la entrada de una termoformadora, caracterizado porque se permite que el tejido permanezca sobre la banda transportadora hasta que la capa superficial del tejido que está en contacto con la banda transportadora, haya sido recalentada por el interior fundido del tejido hasta una temperatura termoformable debajo de aquella a la cual el tejido se pegará a la banda transportadora.The present invention relates to a method for thermoforming hollow objects, which includes: extruding a fabric of thermoplastic material directly into a set of temperature controlled tempering rollers, cooling the upper and lower surface layers of the fabric by passing through said tempering rollers while keeping the interior of the fabric in a molten condition between said surface layers, feeding the partially cooled tissue on a conveyor belt, and transporting the tissue to the entrance of a thermoformer, characterized in that the tissue is allowed to remain on the belt until the surface layer of the tissue in contact with the conveyor belt has been reheated by the molten interior of the tissue to a thermoformable temperature below that at which the tissue will adhere to the conveyor belt.
