Paper-made binder, and manufacturing method and manufacturing apparatus therefor

A system for a paper-made binding comb, the system comprising:

• a combined roll paper generating part 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 a first side surface coated with a high-temperature-sensitive bonding material, and having uncoated other surfaces positioned to face each other;
• a low-temperature pressing roller part configured to combine the inner roll paper and the outer roll paper with each other by melting the low-temperature-sensitive molding material by raising a temperature to the low-temperature and by pressing;
• a slitting part configured to slit the combined roll paper at a predetermined width;
• a cutting part configured to cut the slitted combined roll such that the slitted combined roll has a comb part and a comb-connecting part, thereby forming a flat comb-shaped paper-binding piece;
• a low-temperature raising part configured to raise a temperature to the low-temperature on a heating plate or a heating zone such that only the low-temperature-sensitive molding material in the flat comb-shaped paper-binding piece is melted;
• a transferring part configured to transfer the flat comb-shaped paper-binding piece in which only the low-temperature-sensitive molding material is heated to the low-temperature to a molding apparatus;
• and
• a molding part configured to mold the flat comb-shaped paper-binding piece into a cylindrical shape such that a tip end of the comb part of the flat comb-shaped paper-binding piece corresponds to and faces the comb-connecting part,
• wherein the high-temperature-sensitive bonding material has a melting point at least 10 degrees Celsius higher than a melting point of the low-temperature-sensitive molding material so that the high-temperature-sensitive bonding material is not affected when the combining by the low-temperature and the molding of the cylindrical shape by the raising the temperature to the low-temperature are performed, the low-temperature-sensitive molding material has a function of combining the inner roll paper and the outer roll paper with each other by the raising the temperature to the low-temperature and has a function of molding the flat comb-shaped paper-binding piece into the cylindrical shape, and the high-temperature-sensitive bonding material has a function of bonding a tip end part of the flat comb-shaped paper-binding piece to the comb-connecting part by raising the temperature to a high-temperature when the high-temperature-sensitive bonding material is later inserted and bound into a paper product that is perforated.
