ABSTRACT:
A paper web comprises separable marginal tractor feed portions surrounding a continuous form. The continuous form has regularly longitudinal spaced opposed pairs of transverse cut lines extending from each marginal web portion. The pairs of transverse lines leave an uncut middle portion of the web and furthermore the lines extending from each marginal web portion are of uniform length. A perforation or score line runs longitudinally along the inner end of the transverse lines extending from each marginal portion. This web construction permits the continuous form portion of the web to be folded in the direction of motion of the web over the shortest known distance prior to cutting or separating the web at the opposed pairs of lines to form folded sheets. In another embodiment, the transverse cut lines may be replaced by transverse perforation lines in which case the web is burst at these lines prior to folding.
