Abstract

In a sheet transport having a plurality of rollers for supporting and transporting sheets, a force normal to the plane of the rollers is applied to the individual rollers in the transport An easily adjustable device for applying a uniform normal force to a series of rollers in a sheet transport comprises a tension cable that runs alternately over a roller and under an adjacent pin. This is used in such a way that adjusting the tension of the cable is sufficient to simultaneously adjust the normal force exerted on all the rollers.

In a sheet transport having a plurality of rollers for supporting and transporting sheets, a force normal to the plane of the rollers is applied to the individual rollers in the transport An easily adjustable device for applying a uniform normal force to a series of rollers in a sheet transport comprises a tension cable that runs alternately over a roller and under an adjacent pin. This is used in such a way that adjusting the tension of the cable is sufficient to simultaneously adjust the normal force exerted on all the rollers.

In the figure, a plurality of rollers like roller 10 are mounted on each of the roller shafts 11 which in turn are mounted in bearings 12. Between adjacent rollers are fixed support pins 13 and the tension line 14 runs alternately over a roller and under an adjacent pin. The tension may be adjusted by adjusting spring 15 or other suitable tension adjusting mechanisms whereby the normal load on all rollers is simultaneously adjusted. The bearings 12 have a slot 16 to maintain the tension line in position. The bearings 12 are mounted at each end in vertical slots 17 to permit free movement of the bearing within the slot. The tension line, which may be coated with a lubricant or anti~stickingmaterial, when adjusted provides a uniform normal force N on each of the roller shafts.
