PAPER-MADE BINDER, AND MANUFACTURING METHOD AND MANUFACTURING APPARATUS THEREFOR

WIPO Patent Application WO/2023/136383

A1

Particularly, the present invention relates to a method for manufacturing a paper-made binder. The present invention comprises the steps of: providing a combined roll paper in which an inner roll paper and an outer roll paper are combined at a low temperature by means of a low-temperature-sensitive molding material therebetween, the inner roll paper and the outer roll paper, each having one surface coated with a high-temperature-sensitive bonding material, and having the uncoated other surfaces positioned to face each other; slitting the combined roll paper at a predetermined width, and cutting the slit roll paper to have a comb part and a comb-connecting part, thereby forming a flat comb-shaped paper-binding piece; raising the temperature to the low temperature on a heating plate or in a heating zone such that only the low-temperature-sensitive molding material in the flat comb-shaped paper-binding piece is melted; and transferring, to a molding device by a transfer means, the flat comb-shaped paper-binding piece in which only the low-temperature-sensitive molding material is heated to the low temperature, and molding the flat comb-shaped paper-binding piece into a cylinder shape by means of the molding device such that the front end of the comb part thereof faces the comb-connecting part in correspondence to same.
