Abstract
A device for gripping and decollating a bottom blank comprises a rotary shaft with a flat outer peripheral portion. Suction orifices in the shaft extend through the flat surface portion and communicate with suction cups carried by the shaft. Free outer edges of the suction cups contact the bottom blank, whereupon the application of suction causes the suction cups to contract. The suction orifices include enlarged outer portions for receiving the contracted suction cups such that the bottom blank is pulled flush against the flat surface portion of the shaft for a more effective application of suction forces.
