Abstract
A continuous fan-folded form feeder is applied to a copying machine and has a receiver for the folded form from which the form is trained over the top of the copying machine platen and then beneath the platen to the rear of the copying machine for engagement by form tractors to be progressively fed in stages beneath the platen to a re-fold tray. Drive means for the tractors feeds the form step-by-step in selected increments of length.
Claims12
Fan-folded form copying apparatus comprising a copier for making successive copies of original sheets, a platen pivotally mounted on said copier;
- a fan-folded form receiving tray disposed horizontally above and rearwardly of said platen;
- a form refolding tray disposed horizontally below said platen and rearwardly of said copier;
- means for guiding the form from said receiving tray across said platen and beneath said platen to the rear of said copier;
- intermittently operable drive means for progressively feeding said form beneath said platen to the rear of said copier for gravitation to said refolding tray and means for mounting said drive means on the rear of said copier intermediate said receiving tray and said refolding tray.
Continuous fan-folded form feeding apparatus applicable to a copying machine comprising:
- a plate adapted to be mounted at the rear of the copying machine, an elongated drive shaft rotably supported on said plate, a pair of laterally spaced form tractor means driven by said shaft and anchored on said plate;
- a motor for driving said shaft, control means to energize said motor to drive said shaft and shift said form incrementally;
- a platen pivotally supported by said plate to extend across the top of the copying machine, form receiving and refolding trays carried by said plate, and guide means to direct a form about said platen upon operation of said motor.
Continuous fan-folded form feeding apparatus applicable to a copying machine comprising:
- a plate adapted to be mounted at the rear of the copying machine, an elongated drive shaft rotatably supported on said plate, a pair of laterally spaced form tractor means driven by said shaft and anchored on said plate;
- a motor for driving said shaft, control means to energize said motor to drive said shaft and shift said form incrementally;
- said control means including selective means for de-energizing said motor following selected movement of said form, stop means for arresting rotation of said shaft when said motor is de-energized, and overrunning clutch means between said motor and said shaft operable when said shaft is stopped.
Continuous fan-folded form feeding apparatus applicable to a copying machine comprising:
- a plate adapted to be mounted at the rear of the copying machine, an elongated drive shaft rotatably supported on said plate, a pair of laterally spaced form tractor means driven by said shaft and anchored on said plate;
- a motor for driving said shaft, control means to energize said motor to drive said shaft and shift said form incrementally;
- including housing means for said tractor means and motor, a platen pivotally mounted on said housing means to extend above the copier, form receiving tray means on said housing means, and form refolding tray means mounted on said plate.
