Abstract
Procedimento per la fabbricazione di un film di materiale sintetico termoplastico nonchè per l'avvolgimento di questo film su bobina, ove il film prodotto presenta errori di spessore sistematici in eccesso e in difetto e la bobina risulta praticamente esente da errori di spessore sommatisi durante il procedimento di avvolgimento. Si misura il contorno della bobina risultante dall'avvolgimento del film. In funzione dello scostamento di questo contorno misurato dal contorno cilindrico prestabilito si avvolge il film con profilo inverso degli errori di spessore, e cosi' via, alternando strati di film con un profilo degli errori di spessore e con profilo inverso degli stessi, finchè alla fine risulterà avvolta una bobina con contorno cilindrico sufficientemente esatto.
