ABSTRACT:
Apparatus is disclosed for paper feeding machines for detecting the presence of a load of paper to be fed, and which actuates the feeder to cause paper to be advanced for folding or other operations when no load is detected, and which apparatus includes a scanning head to detect the presence of a load of paper, and electrical circuitry to provide emission signals to the scanning head, compare received signals at the scanning head and, if the signals match, to open a relay and cause the feeder to stop moving a load of paper to position for picking off sheets and further operations such as folding until no load is detected and feeding is resumed.
