Abstract
Workpieces are transported step-by-step by means of transport bars which are provided with grippers and which are longitudinally and transversally displaceable only in cyclic relation to the reciprocating movement of a press. The transport bars have the configuration of hollow profiles which are rigid with respect to bending and torsional stresses, and their ends are rigidly constrained and guided by means of angle brackets and by means of longitudinal guidings and transversal guidings both of which are free of play. Thus, a particularly rigid and a relatively lightweight construction results which allows high working cadences.
