Abstract
Apparatus for applying adhesive onto cards or other inserts to be adhered to signatures on a collecting conveyor. A solenoid valve controlled dispensing nozzle is energized when a card is detected by photodetectors as being in proper position for receiving adhesive. Two sets of photodetectors may be employed and positioned for high and low speeds, respectively. A chopper may be introduced into the energization path of the solenoid valve at low speeds to reduce the amount of adhesive deposited.
