ABSTRACT:
Apparatus and a method are disclosed for associating a relatively wide strip with a set of stacked sheets. The strip, which may be a paper tape, is positioned to intersect a path along which a set of sheets such as paper sheets is advanced. The sheet set is advanced towards the strip and a nip is formed by a pair of opposed belt conveyers so that the downstream edge of the sheet set engages the strip and carries the strip into the nip of the belt conveyers where the strip is folded at least once to the sheet set adjacent the downstream edge of the sheet set. The strip is indexed from a roll to the position in the path of the sheet set. The strip is tensioned and is drawn against a knife edge as the sheet set advanced through the nip to sever the strip from the roll. Pairs of opposed rollers, each pair forming another nip, are disposed adjacent the nip formed by the belt conveyers to cooperate with that nip and form a wider composite nip for folding wider strips and skewed narrower strips.
