ABSTRACT:
A suction type separating element is assembled of a base body supported for a reciprocating vertical movement above the sheet edge, a hollow cylinder of elastomeric material having a circumferentially variable thickness and being provided in the region of the minimum thickness with an inwardly directed constriction preferably in the form of an annular section. The lower base of the elastomeric cylinder is terminated with a suction head adapted for abutment against the sheet to be lifted. Upon the formation of a vacuum in the hollow cylinder, the latter deforms in the range of the constriction and lifts the suction head with the sheet portion upwardly.
