DEFINITION

Classification: 271/140

(under subclass 139) Device wherein the means or the member may be moved in other than a straight line.

(1) Note. In a device of this subclass the pusher movement is usually as follows: an initial movement toward the bottom surface of the bottom sheet, a feeding movement in engagement with the sheet and in the direction of feed parallel to the plane of the sheet, a withdrawal movement away from the surface of the sheet, and a retraction movement parallel to the plane of the sheet and opposite to the feed direction, thus ending in a position ready for the initial movement.
