Abstract
In a document feeding system for unfolding and feeding an elongated web multi-sectional computer form (CF) document from one end of a fan-folded stack in a document input stacking area to an imaging station, a CF document unfolding assistance system is provided by a mounting system cantilever mounting from behind the fan-folded stack a single smoothly radiused cylindrical CF unfolding assistance bar, with a radius of approximately 5 to 8 mm, rotatable between a completely non-obstructing rear storage position and a stationary operating position overlying the document input stacking area, and with a detent system for detaining the CF unfolding assistance bar in the operating position, in which this CF unfolding assistance bar is in a fixed position spaced intermediately above the CF web stack by about 5 cm and extending horizontally over the stack substantially perpendicular to the feeding direction in a position which is spaced closer to the one end of the stack than its opposite end, approximately 11 cm from that one end; for otherwise unobstructed loading, unfolding and feeding of the CF document up and over the unfolding assistance bar towards the imaging station with reduced fo…
