A stationery burster having substantially abutting, rotatably mounted, first and second infeed rolls, substantially abutting, rotatably mounted first and second outfeed rolls spaced from the infeed rolls along a path of stationery travel and a relief in the peripheral surface of the first infeed roll. A rotatable drive is provided for the second infeed and second outfeed rolls such that the peripheral speed of the second outfeed roll with be greater than that of the second infeed roll. The first rolls in each set are idler rolls. The spacing between the infeed and outfeed rolls may be adjusted to accommodate stationery of differing form lengths. A pinfeed tractor device for positively engaging stationery is located ahead of the infeed rolls and there is provided a drive for the tractor device such that the tractor device would drive stationery along the path of stationery travel at a speed in the range from just less to 10% less than the speed the stationery would travel along the path if positively advanced solely by the second infeed roll. A one-way clutch interconnects the tractor device and the tractor drive.

Stationery burster

Stationery printing apparatus for printing indicia at a predetermined position on each form length of continuous business forms stationery assemblies. The apparatus embodies a unique arrangement of a printing device in connection with a form feeding device and lineup indicia so that positive, accurate registration between the printing device and the predetermined position on each form length for receipt of the printing is obtained before a printing is initiated, thereby eliminating any need for registration adjustment during a printing run.
