Vorrichtung zum Halten und Schneiden eines rohrförmigen Körpers.

摘要

A system for handling a flexible thin wall tubular extrudate (17) and for cutting-off a predetermined length sleeve (18) of the extrudate (17) and delivering the sleeve (18) to a discharge station (23). A pair of grippers (7,8) is movably mounted on carriage assemblies (5,6) which move the grippers horizontally and transversely with respect to the axis of the extrudate (17). The leading gripper provides tension to the extrudate and pulls it along a production axis. The grippers completely (7,8) circumferentially envelop the length of sleeve (18) to be cut from the extrudate (17) and retain the shape of the extrudate by applying a vacuum thereto. After completion of the actual cutting operation the leading gripper transfers the severed sleeve to a discharge station (23) and returns to a home position and now becomes the trailing gripper. The previous trailing gripper becomes the leading gripper and continues to advance the extrudate (17) along the production axis and apply tension thereto for the next cutting operation.
