Abstract: A document feed device provided with a pin tractor assembly which includes a pin tractor member supporting a number of feed pins and rotated by a feed shaft, and a body member nonrotatably mounted on the tractor member. Elastically deformable projecting bar with a slit protrudes from the body member. A stationary frame member is formed with a slot extending in the axial direction of the feed shaft. An eyelet portion is formed at each end of the slot. The projecting bar elastically engages the slot, thereby preventing the body member from rotating. As the rotating bar slides within the slot, the pin tractor assembly can move along the feed shaft so that its position is adjusted according to the width of a perforated sheet of material. The assembly may be located in either of two positions, depending on the width of the sheet, as the projecting bar alternatively engages the eyelet portions of the slot. The position of the assembly is shifted by manually operating a knob formed on the body member.

Abstract: The device for paper guidance in printing facilities comprising a paper tractor that transports continuous form paper comprises a plurality of paper guide elements displaceably arranged on a transport shaft dependent on the width of the paper. Compression springs that are supported on the paper guide elements are arranged between the paper guide elements. The hollow-cylindrically fashioned paper guide elements are interrupted in denticular fashion at their surface areas, whereby the respectively neighboring toothings of the paper guide elements displaceably mesh via their teeth in order to thus form a variable-width paper guide cylinder.

Abstract: An adjustable load tear bar mechanism for a friction feed platen (15) that comprises a tear bar assembly (31) and spring loading mechanisms (33) is disclosed. The tear bar assembly (31) comprises a tear bar (51) mounted between a pair of side arms (41, 43) located on opposite ends of the platen (15). The tear bar (51) is an inverted, generally U-shaped channel. Positioned in the channel is a roller shaft (45) on which a plurality of friction feed rollers (47) are mounted. The downstream ends of the side arms (which overlie the platen) are pivotally attached to walls (11, 13) of the printer chassis. The tear bar (51) and roller shaft (45) extend between the upstream ends of the side arms (41, 43). Mounted on the roller shaft (45) so as to be rotatable therewith are arm hooks (53, 55). One of the arm hooks is part of a detent mechanism that includes teeth (125) that co-act with a spring (59) and plunger (57) housed in one of the side arms (43). The position of the teeth (125) and, thus, the rotational position of the roller shaft (45) is controlled by a detent lever (121). The arm hooks (53, 55) are attached by the spring loading mechanisms (33) to the printer chassis. More specifically, the hook arms are attached by hooks (165) to springs (163) mounted in housings (161) connected to the printer chassis upstream of the tear bar (51). The position of the arm hooks (53, 55), which control the pressure applied by the tear bar (51) and friction rollers (47) to the platen (15), is controlled by the latched position of the detent mechanism.
