Device for the linear drive of rod-shaped members

摘要

A device for the linear drive of rod-shaped members (24) has a transport device and a retaining device (42, 44) which are each provided with cylindrical clamping elements (50), the longitudinal axes of which extend axially parallel to the transport device. The clamping elements (50) have an oval cross-section which approximates the shape of a circle when pressure medium is applied to the clamping elements (50). As a result, the clamping elements (50) bear against the rod-shaped member (24) and in this way produce a force-closed connection with it. <IMAGE>
