Abstract: Sheets of paper coming from an office machine such as a copier, are collated in a collator having a vertically extending sheet feeding channel. Collating compartments forming a stack extend up from the channel at a slant. Each collating compartment cooperates with its lower end with one or two sheet feeding rollers and a tiltable guide flap. If a flap is in a passive position the respective transport roller, in cooperation with a counter-pressure roller, will move a sheet past the flap. If the flap is tilted into an active position its curved shape will guide a sheet out of the feeding channel into the respective collating compartment. The tiltable guide flaps are so arranged that they extend on both sides of a horizontal plane and of a vertical plane extending through a rotational axis of the respective sheet feeding roller or rollers. These features assure a sheet feeding free of troubles even if sheets of different lengths and of different thicknesses are to be collated.

Abstract: A device for the feeding of single sheets, for example letterheads, to a xerographic copier instead of the paper supply from a roll. The device is located on a slide-in unit (1) and comprises an exchangeable cassette (4) which holds the supply stack (7). The base of the cassette (6) is tiltable and spring loaded so that the top sheet rests against two friction rollers (10) located above the supply stack (7). The rotation of the friction rollers (10) results in a separation of the sheets of paper by the corner-separators (13). Thereafter, the sheet of paper enters between sets of transport rollers (18, 19), which are magnetically pressed together, and then the sheet is taken over by the feed advance members of the copying apparatus.

Abstract: The bottommost sheet of a stack is withdrawn for the feeding of original copy single sheets to a copying apparatus so that the stack lies in the same sequence after copying. Preliminary separating mechanisms (5, 12) and subsequent downstream separating mechanism (6, 22) are provided. These separating mechanisms each comprise a separating plate (12, 22) provided with a friction facing (20, 24) as well as a rotating separating roller (5, 6). The two rollers (5, 6) are driven by a motor (8) when a single sheet is to be transported.

Abstract: This apparatus removes individual sheets of paper or the like from a stack regardless of the thickness of each sheet. A sheet supply stack support is journaled in a housing in see-saw fashion. A first set of sheet separating rollers is arranged above the downstream end of the support as viewed in the direction of sheet movement. A spring urges the downstream end of the support upwardly and thus sheets on the support against a separating roller. A table is located substantially adjacent the downstream end of a sheet and for cooperation with a pair of sheet separating and transport rollers. Two sheet guides are arranged upstream and downstream, for example, of a platen. The supply stack is arranged upstream of the first sheet guide. The sheet receiving stack is arranged downstream of the platen and so that an upper sheet guide member forms part of a sheet receiving stack tray located substantially above the sheet supply stack.

Abstract: This sheet feeding and collating apparatus has a frame supporting a plurality of upwardly open collating compartments arranged in a row and slanting relative to the vertical. The frame also supports a sheet input feeder as well as a sheet transport and guide mechanism located above the collating compartments so that a sheet advancing roller is substantially aligned with an upper edge of each compartment. At least one tiltable guide gate is located above each compartment. The gates are sequentially operable by respective magnets in response to the movement of a sheet through a light beam to sequentially deflect the sheets into respective compartments. Each interruption of the light beam actuates a stepping switch which in turn connects the operating magnets sequentially to their respective energizing circuit. When the last compartment in a sequence has received a sheet, the stepping switch is reset to begin a new sequence in a ring around fashion.

Further sets of rollers may be arranged downstream of the second set of rollers. These rollers are driven in such a manner that each downstream set runs faster than the next adjacent upstream set of rollers.
