Process to manufacture a back-adhering material for an inner book

摘要

In the manufacture of a hardcover book, a laminated sheet is fed to the inner book spine with a wide roll machine, and the sheet consists of a paper-laminated gauze. The laminate is subsequently treated and has a flat fine creping with a lengthwise elasticity of 5-15%. The end of the laminate sheet is fed to the inner book (12) perpendicular to the lengthwise direction of the inner book spine and pressed onto the glued inner book spine followed by the 10 mm overlaps to either side. The joint material (36) that is applied is elastic perpendicular to the inner book spine. The inner book can then be trimmed and rounded, and the joint (36) stretches without losing stability or tearing.
