小冊子製本機
Document Type and Number:
Japanese Patent JP4887449
Kind Code:
B2
Abstract:
A stack 10 of sheets of sheet material is stapled along an axis 11 and fed to a position from which it is folded along the axis 11 by a blade 13 to form a booklet having a curved spine. The blade 13 also inserts the booklet into a position between clamping jaws 12 and determines its final position therebetween. Rotatable guide rollers 25 guide the sheets into the gap and are fitted with one-way clutches to resist upward movement of the folded sheets upon retraction of the blade from the gap. In a first mode of operation ( figures 1 to 8 ), the curved spine of the booklet protrudes a short distance beyond the jaws. The spine is then flattened by a forming roller which passes along the spine. In a second mode of operation ( figures 9 to 14 ), the spinal portion lies between the jaws and the curved end surface is flattened by the clamping force alone. The first mode is suited to booklets having 10 or more sheets; the second to booklets having fewer than 10 sheets or having loop staples and any number of sheets.
