Method and apparatus for correcting stack lean in a zig-zag folded web wherein a transverse force is cyclically applied to a traveling web so as to vary the motion of the web slightly as it passes through a transverse perforator.

Method and apparatus for correcting stack lean in a zig-zag folded web

A method and apparatus for manufacturing business forms from rolls of paper webs. The webs are divided into at least two groups. The webs of a first group are individually processed as by printing or the like and guided into superimposed relationship. A line of holes is punched simultaneously through all of the webs of the first group, and the webs of such first group are advanced as a unit through the processing operation by a pinned belt engaging such holes. The webs of the second group are individually processed separately from the first group as by printing or the like, and are guided into superimposed relationship beneath the superimposed webs of the first group. A line of holes is punched simultaneously through all of the webs of the second group with some of the holes being in center registration with the line of holes in the first group, and the webs of both groups are advanced as a unit by a pinned belt engaging the line of holes in the webs of both groups. Thereafter, all of the webs are simultaneously further processed as by cross-perforating and stacking. All of said processing operations occur while the webs are moving continuously from said rolls.

Method and apparatus for manufacturing business forms

A method and apparatus for producing a plurality of web units, such as business forms, on a single machine. A plurality of paper webs are simultaneously processed while they are moving through the machine in superposed relationship and in a direction which is common to all of them. The webs are then separated, and their direction of movement is changed to one which is normal to the direction of movement through the machine. The webs are further processed after the direction of movement has been changed as by cross-perforating and folding and by forming them into separate stacks at the front of the machine.

Method and apparatus for producing web units

Method for manufacture of business forms in which at least three superposed continuous business form webs are processed and thereafter separated for individual folding, all but one of the webs being shifted laterally into two-wide folders for zig-zag folding.
