DEFINITION

Classification: 271/182

(under subclass 306) Device wherein the transfer mechanism acts to restrain or hold back the forward movement of each of the succession of sheets that are being conveyed, the action of the transfer mechanism being timed to occur on each successive sheet just as that sheet is at the receiver.

(1) Note. The words "restrain" and "hold back" require (but do not limit the concept to) structure for positively gripping a sheet or for enhancing the frictional hold back characteristics of a retarding surface contacting a sheet. Thus a device having a conveyor belt moving at a relatively reversed or reduced surface speed would not be in this subclass. See search notes below for such a device.

191, and 202, for a device having a conveyor belt moving at a relatively reversed or reduced surface speed (see (1) Note above).
