ABSTRACT:
A card inserter for inserting post cards in a series of bound volumes in motion in a production line which includes a pair of horizontally reciprocated feed plates and associated hoppers arranged on opposite sides of a substantially vertical feed plane. A conveyor is provided in the form of a pair of flat endless belts positioned face to face, the belts being trained about a pair of driven pulleys at the inlet end to define a nip at the feed plane as well as pulleys for maintaining the belts in face to face relation along an angular conveyance path. A V-shaped diverter extends downwardly into the nip. The feed plates are reciprocated inwardly and outwardly in synchronism and have one-way frictional driving connection for simultaneous feeding of the lowermost cards against the diverter and thence into the nip so that the cards are delivered to the volume in register with one another. In the preferred form of the invention the feed plates are provided with vacuum ports to which vacuum is applied during the inward motion, and the feed plates are arcuately surfaced to facilitate separation of the lowermost card, with each feed plate having, in addition, a recessed one-way friction roller. Idler rollers on the inlet pulleys provide auxiliary driving nips enabling a shortened stroke of reciprocation. In one embodiment of the invention provision is made for feeding a third card along the feed plane for sandwiching between the first two cards.
