Abstract: A suction device is movable between a receiving position in which it removes a sheet of film from a magazine and a delivery position in which it transfers the sheet to a conveyor. The effective width of the suction device approximates or equals the width of the smallest sheet of film to be transferred. Sheets having a width greater than the smallest width are gripped in the region of one end thereof leaving the remainder of such a sheet free to deflect. In order to permit proper transfer of all sheets into the conveyor, the latter is provided with grooved rollers which lift the deflected portions of larger sheets into the conveyor. In the delivery position, the suction device is located opposite one portion of the conveyor. The conveying force exerted by this portion of the conveyor is smaller than the gripping force which the suction device exerts on a sheet but larger than the conveying force exerted by a laterally adjacent portion of the conveyor.

Abstract: A brake actuator shaft has a clutch on an inner end which drives a splined sleeve. The splined sleeve engages an inner projection to turn one piston part on another piston part and to effectively lengthen the piston part. When the shaft is turned by a brake lever, it operates an actuator which presses on the piston part and inward projection and which prevents further relative rotation of the piston parts, causing the clutch to slip. A gear on an outer surface of the rotating portion of the piston engages a pinion connected to a manual adjuster. A ratchet in the manual adjuster prevents rotation of the pinion and the gear in the piston shortening direction.

Abstract: The invention relates to a sheet feeder for the individual feeding of sheets to a sheet treating machine. A first sheet pile is carried by a main pile table, and sheets from this sheet pile can be fed by a sheet separating device, optionally via a first feed table, to the sheet treating machine. A further sheet pile is carried by an auxiliary pile table. Sheets can be fed by a second sheet separating device from this further sheet pile to the sheet treating machine, again optionally via a second feed table. Using this arrangement, in place of the sheets from the first pile table, sheets from the auxiliary pile table can be fed to the sheet treating machine without interruption, as the sheet feed from the two piles is carried out in the same rhythm. Preferably a control circuit is used to meter out a selected number of prerun sheets from the auxiliary pile table followed without interruption by another selected number of continuous running sheets.

Abstract: A copy sheet-feeding apparatus comprises a switch and control mechanism. The switch detects an open state of a sheet cover capable of exposing a stack of copy sheet and a closed state of the cover sheet capable of enclosing the stack, and generates signals denoting the open and closed states of the sheet cover. The control mechanism controls a drive mechanism for moving a sheet rest supporting the stack of copy sheets between a first position capable of receiving the copy sheets and a second position capable of supplying the sheet to a copying press. Receiving the signal denoting the open state of the sheet cover from the switch, the control mechanism causes the sheet rest to be moved to the first position, and, receiving the signal denoting the closed state thereof, causes the sheet rest to be moved to the second position.
