OBJECTS OF THE INVENTION Therefore, the present invention has been made with the object of solving the above-mentioned conventional problems and improving the manufacturing efficiency of this type of paperback.

Structure of the Invention In this invention, not only the two cut sheets of the Japanese clothing storage library but also the five cut tapes are molded from thermoplastic material. The cut sheets are then overlapped to form a double-cut sheet, thereby forming the opening edge, bottom edge, and both side edges of the library. Furthermore, two of the cutting tapes are arranged along the opening edge of each cut sheet, bent along the tape center line, and overlapped on both sides of each cut sheet. Furthermore, place one cutting tape along the bottom edge of the double-cut sheet, fold it along the tape center line, overlap it on both sides of the double-cut sheet, and cut the remaining two cutting tapes. The tape is placed along both sides of the double-cut sheet, folded along the tape center line, and superimposed on both sides of the double-cut sheet. Then, the winter cutting tape and the cutting sheet are continuously welded by ultrasonic waves. This overturns the open edges of each cut sheet and covers and connects the bottom edge and both side edges of the double cut sheet.

Furthermore, the cutting tape and the cutting sheet are ultrasonically spot welded at both ends of the opening edge of the library.

Further, the present invention uses two continuous sheets molded from a thermoplastic material and five continuous tapes molded from a thermoplastic material, with each continuous sheet being fed at a distance from each other. Then, two continuous tapes are guided to one side edge of each continuous sheet, bent along the tape center line, overlapped on both sides of each continuous sheet, and continuously ultrasonically welded. Thereafter, each continuous sheet is stacked in the form of a double continuous sheet, one continuous tape is guided to the other side edge of the double continuous sheet, and folded along the tape center line. are superimposed on each other and welded continuously using ultrasonic waves. The double continuous sheet and continuous tape are then cut to length and each cut sheet is fed parallel to its cut edge. Then, guide the remaining two continuous tapes to both cut edges of the double-cut sheet, bend them along the tape center line, overlap them on both sides of the double-cut sheet, and ultrasonically weld them. Two continuous tapes are cut between each cut sheet. Further, the cutting tape and the cut sheet are ultrasonically spot welded at one end of both cut edges of each cut sheet.
