DEFINITION

Classification: 271/102

(under subclass 99) Device wherein the vacuum element moves to and from the stack in a direction generally normal to the plane of the lowermost sheet of the stack.

(1) Note. Although in most devices of this subclass the motion is straight line reciprocation, and in a few such devices the motion is a pivotal oscillation, with either motion, the suction member pulls the foremost sheet away from the stack in a direction perpendicular to the plane of the sheet.

SEE OR SEARCH THIS CLASS, SUBCLASS:

132, for a device wherein a member reciprocating in a direction generally parallel to the plane of the sheet, and a suction means that does not move but is located adjacent the lowermost sheet is activated to ensure that the reciprocating member will engage the lowermost sheet.
