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, a distributing mechanism mounted on the frame for alternately distributing successive lines of weakening in the paper in substantially opposite directions, dispensing rollers carried on the frame for dispensing the continuous strip of paper into the distributing mechanism, folding mechanisms carried by the frame for urging the paper into a folded condition, a gear train for transmitting motive power to the dispensing rollers, the distributing mechanism, and the folding mechanisms, and a power unit to drive the gear train. The gear train includes at least one drive shaft transmitting motive power only to the portion of the gear train actuating the distributing and folding mechanisms. The improvement consists of positioning a differential unit along the drive shaft so that the timing of the distributing and folding mechanisms may be adjusted in relation to the timing of the dispensing rollers.
