  • Patent number: 4953841
    Abstract: Mixed book signatures are fed into a machine which transports them one after the other past a camera where an image of each is captured. Each captured image is directed to an electronic computer which has stored within its memory images of limited areas of interest from selected signatures, as well as the location of each limited area within the overall signatures. As to each captured image, the computer compares the stored image with it, attempting to match each stored image with that location in the captured image corresponding to the location for the stored image. If the captured image identifies with a stored image, a controller activates a reject device along the conveyor, and that device diverts the identified signature from the conveyor. A separate reject device exists for each stored image, so like signatures are diverted and isolated at the same locations along the conveyor.

  • Patent number: 4134579
    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.
