Abstract
A variable-width friction-feed paper handling apparatus includes a rotatable drive shaft and a stabilizing shaft spaced therefrom and parallel thereto. Two carriage assemblies bridge the drive shaft and stabilizing shaft and are supported thereby and are adapted for sliding movement longitudinally therealong for accommodating varying widths of paper therebetween. Each carriage assembly includes a drive roller coaxial with the drive shaft for rotation thereby and a pivoting gate which rotatably carries a pressure roller, the gate being movable between a loading position accommodating placement of paper between the carriage assemblies and a feeding position wherein the pressure roller is in parallel cooperation with the drive roller frictionally to feed paper therebetween. Over-center springs hold the gate in its two positions and leaf springs resiliently mount the pressure roller. Each carriage assembly carries paper guide device.
