Abstract

In an apparatus for transporting thin boards, in particular coated printed circuit boards, comprising rows of spaced-apart grippers (2) which lie opposite one another and are arranged on a rod (3), in order to prevent the thin boards from sagging when transported, tension is applied to a rod (3), at least on one side of the printed circuit board (1), by an elastic device (15, 20), in order to tension the printed circuit board which has been gripped.
