Abstract
Secondo l'invenzione viene realizzato un dispositivo elettrico di trazione (10) per una macchina da stampa, che presenta un rullo di trazione (120) azionato da un proprio motore (8), per estrarre un nastro di materiale stampato da uno scambiatore di rulli (16), un rullo premitore (130) per premere il nastro di materiale stampato contro il rullo di trazione (120) in direzione di scorrimento del nastro di materiale stampato, per la compensazione di oscillazioni della tensione del nastro. Il dispositivo di trazione (10) presenta una unità di controllo e regolazione (7), comandata da una calcolatrice (1') del posto di comando della macchina da stampa, per l'indicazione del numero di giri nominale del rullo di trazione (120) azionato dal motore (8) del dispositivo di trazione. Il rullo di trazione (120) viene sollecitato dal nastro di materiale stampato con la tensione del nastro stesso, generata dal rullo oscillante (100) e dal rullo premitore (130). Il rullo oscillante (100) trasmette attraverso un indicatore di angolo (11) la sua deviazione angolare dalla posizione neutra all'unità di controllo e regolazione (7), affinché essa possa conformemente controllare e regolare il numero di giri del motore (8) del dispositivo di trazione. Il dispositivo di trazione (10) è munito preferibilmente di dispositivi di distacco per evitare avvolgimenti del rullo di trazione in caso di strappo del nastro di materiale stampato (140). Il rullo di trazione (120) è munito preferibilmente di sensori ottici, che in base della struttura della superficie del rullo di trazione (120) riconoscono un avvolgimento di quest'ultimo.(Figura 1).
