Abstract: A sprocket drive device for a computer form feeder for transporting a computer printout web having predeterminedly spaced apertures along the edges thereof along the upper and lower surfaces and about a free end of a copyboard overlying the copy platen of a copying machine, including a pin chain assembly mounted on spaced driven sprocket and idler wheels. The pin chain assembly includes a plurality of predeterminedly spaced pins extending therefrom for receipt in the spaced apertures of the web. The pins travel along an endless path between the wheels spaced from the upper and lower surfaces of the copyboard, respectively. A guide and stripper member is provided on the sprocket drive for guiding the web from the pins to the copyboard surface and vice-versa while avoiding the tearing of the web material about the apertures. The guide and stripper member includes upper and lower central portions extending between the wheels for guiding the web along upper and lower planes passing through the base of the pins.

Abstract: A guide chute arrangement for an apparatus used to feed a computer form printout web to the original document platen of a copying machine which includes a pivotally mounted copyboard overlying the platen over and about which the web is fed, includes an upper chute assembly for guiding the web between the upper surface of the copyboard and a first supply tray and a lower chute assembly for guiding the web between the lower surface of the copyboard and a second supply tray. Each of the chute assemblies includes complementarily, predeterminedly shaped upper and lower walls forming channels therebetween. The lower walls of the chute assemblies are fixedly mounted. The upper wall of the upper chute assembly is mounted for pivotal movement on extension arms which permit the movement of the upper wall away from the lower wall for easy threading of the web thereinto.
