Abstract: An improved pin driven collator with a freely rotatable platen for crimping a plurality of single sheets into a continuous multiple copy forms is disclosed. The collator assembly comprises a modular assembly having a frame to fix a pin drive, rotary plunger and platen into preselected spatial alignment and to maintain such components in dynamic registry. The rotary plunger is fixed to a shaft which also carries a drive sprocket which is engaged by an endless pin chain loop of the pin drive. A pair of mirror image modular collating assemblies are supported and interconnected by a pair of shafts, a splined drive shaft and a stabilizing shaft. The modular assemblies may slide along the shafts to adjust for varying paper width without disturbing the spatial alignment of the components or their dynamic registry.

Abstract: An attachment for an offset press, of the type adapted to process individual sheets of paper, to enable it to feed and print continuous form in proper registery. In one embodiment the invention includes a paper feeding station downstream of the press and a separate registration station upstream of the press. The paper feeding station employs an adjustable rotating circumferential segment, driven off the press, cooperating with a draw roller to intermittently engage the continuous form paper, draw a predetermined increment through the press and then disengage from the paper. In another embodiment the paper feeding function is accomplished by the printing blanket which discontinuously engages the paper and feeds it through the press in predetermined increments thereafter disengaging from the paper after each of the increments is fed.
