Abstract (en)
The unwinding device for web rolls comprises: two pairs of mobile arms (45A, 45B) for supporting rolls (B0, B1, B2, B3) of web (N0, N1, N2, N3) each with members (51A, 51B) for engaging the rolls; a supporting structure (3, 11) for said pairs of arms; two lateral stations (13, 15) for loading full rolls; and an intermediate station (17) for unloading the used rolls. <??>The structure presents a supporting crosspiece (11) along which the pairs of arms (45A, 45B) translate, the crosspiece developing over said two lateral stations and said intermediate station. The arms are developed downwards from said crosspiece. Furthermore, means are provided to align the roll engagement members carried by the arms with the axis of the roll to be engaged by said members. <IMAGE>
