Abstract

Una ribobinatrice di materiale in foglio, quale carta o simile, comprendente una terna di rulli (1, 2, 3) determinanti una culla in cui avviene l'avvolgimento del materiale in foglio (W) su un'anima (C), introdotta tra una coppia di rulli (1, 2), il terzo rullo (3) essendo ad asse variabile per consentire l'aumento di diametro del rotolo informazione e l'espulsione del rotolo a formato (R), in cui almeno uno dei rulli (1, 2, 3) è a diametro variabile e assume diametri diversi nella fase di avvolgimento del rotolo e nella fase di "scambio" cioè di introduzione dell'anima nuova (C) nella culla di avvolgimento e di espulsione del rotolo formato (R).A rewinder of sheet material, such as paper or the like, comprising a triad of rollers (1, 2, 3) determining a cradle in which the sheet material (W) is wound on a core (C), introduced between a pair of rollers (1, 2), the third roller (3) being with variable axis to allow the increase in diameter of the information roll and the expulsion of the format roll (R), wherein at least one of the rollers (1 , 2, 3) has a variable diameter and takes on different diameters in the roll winding phase and in the "exchange" phase, that is, the introduction of the new core (C) into the winding and expulsion cradle of the formed roll (R).
