METHOD AND APPARATUS FOR GLUING AND BOOKBINDING AS WELL AS IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To enable a line width of a glue coating part to be changed and to enable an intermittently broken line-like or dotted line-like glue coating part to be formed in an apparatus for gluing and bookbinding to form a line-like glue coating part in a sheet conveying direction near a side edge of a sheet to be conveyed. SOLUTION: A method for gluing and bookbinding comprises the steps of discharging the glue from a nozzle 81 of a glue discharge means 80, and forming the line-like glue coating part Nb in the sheet conveying direction near the side edge of the sheet S to be conveyed. The method further comprises the steps of variably controlling the conveying speed of the sheet S passing through the glue coating position by the nozzle 81, and changing at least the width (w) and a length (m) of the glue coating on the sheet S.
