Flat material transport device in wet chemical treatment plant e.g. for circuit boards or conductor foils, uses cooperating transport rollers with offset rounded peripheral beads

摘要

The transport device uses at least one pair of cooperating upper and lower rollers (1,2) coupled to a transport drive, the rollers each provided with at least one rounded peripheral bead (7), the beads of the roller on one side of the transport plane offset from the beads of the roller on the opposite side of the transport plane. An Independent claim for a transport method for flat material is also included.
