Abstract

The device is for positioning forms feeding tractors. Previously, two pairs of tractors were located near the print line. It was necessary, therefore, to provide guides to prevent buckling of the forms passing through the carriage. This resulted in an expensive carriage and one which was difficult to load and operate. In the device shown, one pair of entrance tractors 10 is positioned near the print line 12 and the other pair of tractors 14 is positioned at the exit 16 where the forms leave the carriage 18 for stacker 20. A smooth curved guide 22 provides the forms with a path from the entrance tractors to the exit tractors.

Controlled Path for Continuous Form Feeding

The device is for positioning forms feeding tractors. Previously, two pairs of tractors were located near the print line. It was necessary, therefore, to provide guides to prevent buckling of the forms passing through the carriage. This resulted in an expensive carriage and one which was difficult to load and operate. In the device shown, one pair of entrance tractors 10 is positioned near the print line 12 and the other pair of tractors 14 is positioned at the exit 16 where the forms leave the carriage 18 for stacker 20. A smooth curved guide 22 provides the forms with a path from the entrance tractors to the exit tractors.

This arrangement eliminates the need for guides on top of the forms and provides better vision of the printed matter. Further, the paper is power driven in the direction of stacking to reduce stacking problems. Also, by spacing the tractors further apart than previously, the paper is held tautly at the print line.
