Vorrichtung zur Unterstützung und Einspannung einer Papierrolle während der Durchtrennung desselben durch eine Säge

摘要

The apparatus for holding a log or long roll (L) of web material during the cutting thereof along a plane perpendicular to the log axis (X), includes: a plurality of clamping elements (27) distributed in a circle around the log (L). The clamping elements (27) can be moved so as to clamp the log (L) during the cut and also to be released so as to allow the log to axially move between cuts. At least one actuator (49) causes the movement of the clamping elements (27), and connectors (39,41) which connect the clamping elements (27) to one another to provide a simultaneous movement thereof by said actuator (49). Each clamping element (27) pivots around an axis (17) so as to cause clamping of the log (L). The connectors (39,41) control the pivoting of said clamping elements (27).
