ABSTRACT:
A method of using a buckle for relieving the stresses in sheets caused by differential displacements of drive nips during the registration process includes creating a buckle between pre-registration nips and registration nips. The velocities of the pre-registration nips and registration nips are closely controlled so that the magnitude of buckle between them is large enough to relieve the stresses in the sheet during the registration process, yet small enough to not interfere with the registration process.
