Abstract

A multiple-part continuous form is provided with horizontal perforations horizontally offset or staggered among overlapped parts of the form. The horizontal perforation for each part of the form is wide enough to accommodate the thicknesses of the folded edges of the other parts. This structure minimizes a form tenting when it is unfolded and avoids a form jam and a printing misalignment when it is fed and printed in a printer. As shown in Fig. 1, the conventional multiple-part continuous form 1 has horizontal perforations 2 of almost "0" width. This causes a form tenting 3 at the perforation and misalignments among the overlapped parts of the unfolded form. To overcome these problems, the adjacent parts of the conventional form are glued together.
