Patent ID: 7578502

Claim:
A sheet delivery for a printing press, comprising: a first linear guide defining a first axis; a second linear guide defining a second axis enclosing an angle other than zero with said first axis; a single holding crossmember mounted in said first linear guide and in said second linear guide for periodic to and fro movement along said first axis with a first amplitude and along said second axis with a second amplitude; and motors respectively assigned to said first and second linear guides and configured to drive the periodic to and fro movements of said holding crossmember, said motors being travelling-wave motors; and a control device connected to said motors for controlling said motors; said control device configured for driving said motors to move said holding crossmember along an intrinsically closed circulation path; said control device, said first and second linear guides and said motors being configured so that said second amplitude is a plurality of times greater than said first amplitude.
