Abstract: A machine for making forms sets comprising a continuous bottom sheet and multiple continuous form sheets, includes a central row of assembly stations on either side of which are provided form set sheet supply rolls and form set sheet processing equipment for enabling uninterrupted feeding of bottom and form set sheets to the machine while the form set sheets are processed and assembled to the bottom sheets of the form set. The upper form sheets are fed continuously to the assembly station using a special arrangement of feed and guide rollers, each successive set of form sheets being fed from alternate sides of the assembly station. Assembled form sets are finally perforated, folded and stacked in a desired manner by the machine.
