Abstract
Un método para la fabricación de envueltas de material termoplástico de encogimiento por calor arrollando para ello una hoja de material alrededor de un útil de conformación y uniendo entre sí los extremos de la hoja caracterizado porque, antes de arrollar la hoja de material alrededor del útil de conformación, se pre calienta la misma a lo largo de toda su longitud al menos por el lado que mira hacia el útil de conformación, hasta una temperatura que coincide sustancialmente con la temperatura de reblandecimiento del material, y porque se somete el extremo frontal de la hoja de material en el lado que mira hacia el útil a un calentamiento intensivo complementario hasta una temperatura que excede de aquella a la cual se inicia el encogimiento, de modo que, debido a la capacidad de encogimiento del material, se comunica al citado extremo de la hoja una forma curvada en dirección hacia el útil.
