DEFINITION

Classification: 271/192

(under subclass 189) Device wherein the transfer mechanism includes two means disposed to receive one or more successive sheets and temporarily hold such sheet (s) by contacting the two side borders of the sheet (s) that extend in a direction parallel to the direction of travel thereof, which means releases the sheet (s) so held by turning one of the means in one rotational direction and simultaneously turning the other of the means in the opposite rotational direction.

(1) Note. For the purposes of this subclass oscillation (i.e., to-and-fro partial rotation) of two opposite members is equivalent to unidirectional rotation, provided that the members oscillate in opposite directions simultaneously.
