Abstract
Abstract Successively connected business forms are produced by feeding a plurality of paper webs and interleaving carbon webs from corresponding supply rolls into overlying relation and gluing together corresponding longitudinal edge portions of the webs. Lines of cross-perforations are formed in the overlying webs at longitudinally spaced intervals, and the edge portions of the webs are bonded or welded together across or adjacent each line of cross-perforations by a plurality of transversely extending impressions of intermeshing fibers which prevents relative longitudinal shifting of the webs when the webs are zig-zag folded before the glue sets. Preferably, the impressions are located at the fine longitudinal glue lines joining the paper webs to provide fast drying of the glue.

In apparatus for continuously producing successively connected business forms each having multiple interconnected copies, comprising means for rotatably supporting a plurality of rolls of paper webs, means for feeding said paper webs from the corresponding supply rolls into overlying relation along a predetermined path, means for corss-perforating the overlying said webs along longitudinally spaced lines to define the successively connected said forms, and means for applying adhesive to at least one marginal edge portion of said webs to connect said webs together, the improvement comprising impacting wheels located on opposite sides of the overlying webs and having impacting teeth operative on the webs to form longitudinally spaced groups of impressions extending transversely within the same said marginal edge portion of the overlying said webs adjacent to each side of the cross-perforations, said impressions being effective to lock said webs against relative longitudinal shifting during zig-zag folding of said webs about the crossperforations, means supporting said wheels for rotation in correlation to movement of the overlaid webs, and means for maintaining a predetermined space between said wheels to cause a pressure bonding of the webs by said impacting teeth.
Claim 3
Dependent Claim
32 words
Apparatus as defined in claim 1 wherein both said impacting wheels having V-shaped teeth in spaced groups about their circumference, and said wheels are spaced to cause intermeshing of said V-shaped teeth.
Claim 4
Dependent Claim
164 words
An improved method of continuously producing successively connected business forms each having multiple copies, comprising the steps of feeding a plurality of paper webs from corresponding supply rolls into overlying relation, cross-perforating the overlying said webs along longitudinally spaced lines to define the successively connected said forms, applying glue to at least one edge portion of said webs for securing the webs along their edges, moving the same edge portion of said webs between opposed closely spaced wheel members having impacting teeth and maintaining the spacing of said wheel members to cause pressure bonding of the webs in groups of small corrugated impressions extending transversely of the webs at longitudinally spaced intervals to cause intermingling of the fibers of the adjacent webs, said wheel members being rotated in timed relation to the movement of said webs so as to arrange said impressions adjacent opposite sides of said cross-perforations to lock said webs against relative longitudinal shifting in response to zig-zag folding of said webs.
Claim 5
Dependent Claim
164 words
An improved method of continuously producing successively connected business forms each having multiple copies, comprising the steps of feeding a plurality of paper webs from corresponding supply rolls into overlying relation, cross-perforating the overlying said webs along longitudinally spaced lines to define the successively connected said forms, applying glue to at least one edge portion of said webs for securing the webs along their edges, moving the same edge portion of said webs between opposed closely spaced wheel members having impacting teeth and maintaining the spacing of said wheel members to cause pressure bonding of the webs in groups of small corrugated impressions extending transversely of the webs at longitudinally spaced intervals to cause intermingling of the fibers of the adjacent webs, said wheel members being rotated in timed relation to the movement of said webs so as to arrange said impressions adjacent opposite sides of said cross-perforations to lock said webs against relative longitudinal shifting in response to zig-zag folding of said webs.
Claim 6
Dependent Claim
31 words
The method defined in claim 3 wherein said impressions are formed directly overlying the glued parts of said edge portion of said webs to promote the adhesive action of the glue.
