  • Patent number: 4640502
    Abstract: An attachable feed and delivery system for envelopes in a high speed, batch printer (14) environment is described. Included is a hopper (10) having input (30) and output sections (32) separated from each other by a spring loaded bail (34). The transport path to and from the print station includes a picker/separator (90) located adjacent to the input section of the hopper. Fresh envelopes are urged toward the pick area by the spring loaded bail (34). Endless belts (56) passing through the base (50) of the hopper (10) assist in urging printed envelopes into the output area (32).

  • Patent number: 4478400
    Abstract: An envelope feeder for a duplicating press having a suction feeder wherein the envelope feeder includes a conveyer for transferring envelopes one at a time from a magazine storing a supply stack to a feed stack from which the suction feeder of the duplicating press removes the envelopes one at a time from the top of the stack. The conveyer coacts with the magazine and other means for taking the envelopes from the bottom of the supply stack one at a time and feeding them to the bottom of the feed stack at the press. A detector at the feed stack shuts down the conveyer when the feed stack reaches a predetermined height, and thereafter starts the conveyer when the stack diminishes to a given level.

  • Patent number: 4171129
    Abstract: A document transport for a document scanning device has an elevator for locating a stack of documents to be fed automatically into position to be scanned. The top document is removed from the stack by a feed roller. Other documents which may become entrained with the top document are returned to the stack by separation rollers. The top document is driven into the scanning device against an alignment gate and this action eliminates any skew in the position of the document. At a read or scan station beyond the gate, which is reached by the document once the alignment gate has been withdrawn, the data on the document is scanned as the document is moved by read rollers in a controlled fashion. As the document leaves the read station it is trapped between the two single opposing belts in a buffer unit, which move the document at the spped of the scanning rollers.

  • Patent number: 4154437
    Abstract: A detector mechanism and system for currency dispensers for automatic banking equipment which senses the presence of multiple or double bills, called "doubles," at any bill location in a series of bills intended to be fed one by one in a path of travel from a supply of bills to a place of delivery to a customer. The bill thickness of each bill is gauged continuously while moving in the path of travel, and the thickness measurements are time averaged over substantially the entire length of the gauged portion of the bill. The averaged and normal bill thicknesses are compared to determine if the averaged thickness is greater than the normal thickness by a predetermined amount. A greater thickness determination generates a signal of the presence of doubles, and the signal actuates means to reject the doubles while moving in the path of travel before delivery of the doubles to a customer.

  • Patent number: 4134580
    Abstract: Folded signatures of lightweight stock are fed in a direction parallel to the backbone of the signatures and deposited in sets of predetermined number and in shingled relation onto a main conveyor moving transverse to the direction of feed from the supply stack. The main conveyor deposits the signatures on the top of a stack in the hopper of a gathering machine. The height of the stack in the hopper is sensed, and this is used to control feeding from the supply stack. Preferably, the supply stack is held in a hopper with the signatures resting on a second or supply conveyor which extends upwardly and outwardly from the main conveyor so that adjacent loading machines can be nested to reduce space requirements.

  • Patent number: 3978973
    Abstract: A machine that receives four rows of completely separated but closely spaced cartons from a customer printing and cutting press, and spaces each carton laterally and longitudinally from its neighbors for non-interference therewith. The machine aligns each independent stream of cartons with the longitudinal dimension of the overall machine and directs the streams of cartons to a switching device intended to control carton traffic to a primary automated stacking process or to an essentially secondary manual stacking process. The primary automated process passes the streams of cartons through an underlapping process, over an inspection table, through an inverting process, into a rate controlling hopper. From the rate controlling hopper, the cartons of each stream pass over a set of laterally disposed conveyors and into a discrete stack of cartons formed within a vertical hopper system that is the output receiver of this machine.
