Abstract
In a continuous form document feeder for a copier, for incrementally feeding a computer form or the like web document from a fan-folded stack thereof to the imaging station of a copier with a web feeder, the improvement in the supply hopper in which the fan-fold web stack is stacked and from which the web is unfolded and fed out to be copied with said web feeder, wherein said supply hopper has a generally horizontal main stack supporting floor for supporting the principal portion of the stack of fan-fold web, a downstream stack edge retaining low wall extending upwardly not substantially above the maximum height of the stack of web to be fed from the supply hopper and adjacent the end of the supply hopper from which the web is to be fed out to be copied, this low wall being adapted to retain one end of the stack of fan-fold web in the supply hopper but to provide low friction and low angle feeding of the web from the stack thereover, and a raised stack floor portion adjacent the end of the supply hopper opposite from the low wall and extending upwardly from the main floor to slightly tilt upwardly (relative to the rest of the stack) the end of the stack of fan-fold web in the supply hopper opposite from the low wall sufficiently to substantially reduce variations in the resistance to unfolding and feeding of the web from the stack thereof by the web feeder. This raised stack floor portion preferably extends upwardly at approximately 10 degrees to the main floor and is adapted to raise the upstream end of the stack by at least approximately 1 centimeter relative to the rest of the stack.
