DEFINITION

Classification: 271/100

(under subclass 99) Device wherein the vacuum element moves to and from the stack, and during its movement away from the stack engages a portion of the lowermost sheet adjacent one of the edges or corners thereof to move that portion away from the undisturbed residue of the stack.

(1) Note. Although most devices of this and the indented subclasses include a suction member that oscillates by pivoting in the arc of a circle, a few such devices include a suction member that oscillates by reciprocating in a straight line to perform the same type of bending of the sheet margin.

SEE OR SEARCH THIS CLASS, SUBCLASS:

106, for a device wherein a suction member bends a portion of the foremost (usually the topmost) sheet of a stack prior to removal.
