Abstract

Un avvolgitore doppio per linee di produzione di pellicole tubolari estruse secondo cui la pellicola appiattita tubolare viene tagliata lungo i bordi separando le due pellicole piane che sono poi avvolte in bobine separate. L'avvolgitore comprende due gruppi di avvolgimento contrapposti, mezzi di separazione delle pellicole piane, tali da orientare una pellicola in una direzione sostanzialmente opposta all'altra pellicola, nonché mezzi di controllo della tensione delle pellicole in fase di avvolgimento; l'avvolgitore comprende inoltre un sistema combinato di traino di ciascuna bobina mediante un azionamento assiale e/o rispettivamente tangenziale delle bobine, nonché mezzi per il cambio automatico delle bobine con subbi vuoti, senza necessità di adesivo. L'avvolgitore, può inoltre essere provvisto di mezzi per un trattamento di ossidazione superficiale su almeno un lato di ciascuna pellicola piana.A double winder for extruded tubular film production lines according to which the flattened tubular film is cut along the edges separating the two flat films which are then wrapped in separate reels. The winder comprises two opposed winding groups, means for separating the flat films, such as to orient a film in a direction substantially opposite to the other film, as well as means for controlling the tension of the films being wound; the rewinder also comprises a combined system for pulling each reel by means of an axial and / or tangential drive of the reels, as well as means for automatically changing the reels with empty beams, without the need for adhesive. The rewinder can also be provided with means for a surface oxidation treatment on at least one side of each flat film.
