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 cylindr icalCF unfolding assistance bar, with a radius of approx imately 5 to 8 mm, rotatablebetween a completely non-obstructing rear storag e position and a stationary operating position overlying the document input stacking area, and with a de tentsystem 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 horizontal ly over the stack substantially perpendicular to the feeding direction in a pos ition 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 assistanc e bar towards the imaging station with reduced forces and improved control.</S DOAB>
