METHOD AND APPARATUS FOR MAKING TWELVE-PAGE BOOKLETS OR SIGNATURES

摘要

Method and apparatus for use with a web printing press and associated conventional folding devices for the continuous production from a single web of 12 page pasted booklets or signatures instead of or in addition to the eight page, or multiples thereof, booklets or signatures, pasted or not, which are customarily produced on web press and folder combinations. The apparatus constitutes a device for applying a thin continuous line of adhesive to both opposing surfaces of the printed web with said lines of adhesive extending lengthwise of and lying very close to a free edge of the web as it progresses from the press rolls to the first unit of the folding apparatus. The edge with applied adhesive is then folded into the interior of the 12 page assembly so as to bind all pages of the same firmly together.
