Patent ID: 8291955

Claim:
An apparatus of manufacturing a pipe-shaped insulator comprising: a mat feeding roller on which a fiberglass mat is wound; a plurality of transportation rollers to transport the fiberglass mat drawn from the mat feeding roller; a coating roller to coat a binder over a surface of the fiberglass mat during transportation of the fiberglass mat; a forming roller on which the fiberglass mat, coated with the binder, is wound in plural times to form a pipe-shaped insulator having a predetermined thickness and a predetermined diameter; a squeeze roller disposed parallel to the forming roller and adapted to be rotated by a motor and a power transmission member; a binder supply means, adapted to supply the binder to the squeeze roller for coating onto the fiberglass mat; a pressure regulator to vertically move the squeeze roller so as to press the fiberglass mat being wound on the forming roller and to enable coating of the binder on the fiberglass mat; an encoder to measure a transported length of the fiberglass mat; a cutting unit to be moved to a cutting position so as to diagonally cut the fiberglass mat after a desired length of the fiberglass mat is transported and then, to be returned to an original position hereof after completing the diagonal cutting of the fiberglass mat; and a control system, a sensor, and a plurality of drive motors and power transmission members.
