Bookmaking method
摘要:
In bookmaking, a sheet bundle is held in a substantially vertical posture. At first an adhesive is applied to a bottom edge of the sheet bundle in a condition that the bottom edge of the sheet bundle and an adhesive application member are pressed together with a first contact pressure to apply the adhesive between the sheets. Then, the adhesive is applied to the bottom edge in a condition that the bottom edge of the sheet bundle and adhesive application member are pressed together with a second contact pressure weaker than the first contact pressure, or are in a non-contact situation.
