摘要： A machine for producing zigzag folds in continuous business forms or like strip material. The strip material moves over a horizontal feed roller and then downward between a pair of opposed endless belt units to an underlying support surface. A hold-down roller is biased to engage the feed roller, with the material sandwiched therebetween, immediately above the point at which the material discharges from the feed roller. The material, upon engagement with the support surface, loops alternately in opposite directions beneath the belt units and between spaced stops, one of which is rounded so as to allow for a smooth continuous movement of the folded material therebeyond. Material boosting means periodically engage the looped material immediately prior to engagement with the stops so as to insure a proper movement thereagainst.
