ABSTRACT:
Improved apparatus for producing continuous form stationery by folding a strip of paper along lines of weakening formed therein. The apparatus includes a frame; endless belt units mounted on the frame for alternately distributing successive lines of weakening in the paper in substantially opposite directions, each belt unit including a distribution roller adjacent and parallelably disposed to a roller in the companion belt unit; a feed roller for directing the continuous strip of paper between the adjacent distribution rollers; a support surface for receiving paper distributed by the endless belt units; a mechanism for periodically tamping the paper distributed by the endless belt units, the tamping mechanism assisting in the folding and positioning the paper on the support surface; and, a pair of paper stop assemblies positioned above the support surface, each of the paper stop assemblies being spaced apart from the other and on an opposite side of a midline lying between and parallel to the adjacent distribution rollers and having at least one upstanding face for stopping the lateral travel of creased edges of paper distributed away from the midline by the endless belt units. The improvement consists of providing paper stop assemblies which can be positioned beneath the distribution rollers so that the continuous strip of paper can be folded into short segments.
