ABSTRACT:
Apparatus for feeding marginally punched record material comprises a main support member, and a plurality of drive pins mounted to the main support member for movement along a predefined path past a first location at which record material is inserted into the apparatus. Means included on the main support member adjacent the first location facilitates the buckling of record material inserted into the apparatus in a direction away from the pins during movement of the pins along the predefined path when there is no initial engagement of a pin with a marginal opening of the record material. When a pin thereafter moves into substantial registration with a marginal opening of the record material, the natural bias of the buckled portion of the record material in the direction of the pins will return it to a substantially unbuckled state to thereby engage the pin with the opening.
