摘要： A hinge for thermoplastic material particularly suitable for loose-leaf binder covers is constructed by embedding an embossed welding die into the thermoplastic material to a depth less than the full height of the embossment so that no vertical lines are produced in the thermoplastic by the longitudinal edges of the die. The resulting surface of the thermoplastic is a hinge containing indentations corresponding to the pattern of the embossed die, which permit the thermoplastic to be folded at the hinge area.

摘要： A hinge for thermoplastic material particularly suitable for loose-leaf binder covers is constructed by embedding an embossed welding die into the thermoplastic material to a depth less than the full height of the embossment so that no vertical lines are produced in the themoplastic by the longitudinal edges of the die. The resulting surface of the thermoplastic is a hinge containing indentations corresponding to the pattern of the embossed die, which permit the thermoplastic to be folded at the hinge area.
