摘要

The device (1) has suction devices (13, 14) moved forwards and backwards in an oblique direction (S), which is oriented in a transport direction (T) and at an angle (alpha) to a floor central line. The suction devices are arranged at a holder, which is hingedly connected with ends of two parallel pivot arms. One of the arms is pivotably driven transverse to the transport direction. Other ends of the pivot arms are hingedly connected with support carriage. The carriage is movably driven forwards and backwards in a guide rail in the oblique direction.
