ABSTRACT:
A supply hopper for holding a stack of fanfold paper and guiding such fanfold paper for reliable feeding as it is withdrawn from the supply hopper. The supply hopper comprises a tray for supporting a stack of fanfold paper, the tray including a base member oriented at an angle in the range of between 25.degree.-45.degree. from the horizontal. A stop member is connected to the base member along the lower marginal edge thereof, the stop member and the base member forming an included angle of substantially 90.degree.. Further, a guide member is supported by the tray substantially above a fanfold paper stack supported on the tray at a height sufficient to lift the topmost individual panel of the stack at least partially off the stack when the fanfold paper is threaded over the guide member. A bail assembly is connected to the tray extending away from the base member of the tray on the opposite side of the stop member from the base member. As such, the bail assembly acts as a damper on fanfold paper being withdrawn from the stack of fanfold paper passing from such stack supported on the tray over the guide member and below the bail assembly.
