BOOKLET MAKING METHOD AND APPARATUS

摘要

A booklet making method includes: cutting a web of paper on one side and on another side into first and second continuous sheets, alternately bonding the first and second continuous sheets widthwise with a setting paste and a throwaway paste to form a double set continuous sheet of paper, and cutting the double set continuous sheet of paper into split double sheets of a selected longitudinal length. A plurality of split double sheets is integrally bound with an integrating paste to form a booklet-like product. Portions of the booklet-like product which are pasted and bonded with the throwaway paste are cut off to provide a plurality of booklets. Thus, by the booklet making method, booklets having an odd number of leaves or pages are formed without waste of paper and with reduced paper jams.

主权项

1. A booklet making method comprising the steps of:
cutting a web of paper having a plurality of booklet page sections, which in its transport direction are spaced apart from one another, on each of its widthwise one and other sides, into a first and a second continuous sheet of paper on said widthwise one and other sides; laying the first and second continuous sheets of paper one on the other, and forming a double set continuous sheet of paper by bonding widthwise one side edges of a pair of overlapping such booklet page sections together with a throwaway paste and bonding widthwise other side edges of a next adjacent pair of such overlapping booklet page sections together with a setting paste; cutting said double set continuous sheet of paper into split double sheets comprising pairs of sheets having such pairs of overlapping booklet page sections; laying said split double sheets one on another and bonding widthwise other side edges of adjacent sheets of adjacent two of said split double sheets together with an integrating paste, thereby forming a booklet-like product comprising an odd number of sheets and an even number of sheets both of which are individually bound at the said widthwise other side edges; and cutting off those edge portions of said split double sheets which are bonded with the throwaway paste, thereby forming a plurality of booklets which comprise the sheets of the said page sections.
