LOOPER

PROBLEM TO BE SOLVED: To obtain a compact looper having a simple route by making the looper wind and support more than two lines of metal strips, bringing at least one of the winding and supporting part of the looper into contact with the metal strip freely rotating and making them into plural guide rollers having mutually parallel axes. SOLUTION: At least, one of the winding and supporting part of a looper 3 is composed of plural guide rollers 7 which are brought into contact with metal strip 1 freely rotating and which have mutually parallel axes so that more than two lines of the metal strips 1 are wound and supported. These guide rollers 7 are assembled in a frame body 8, the frame body 8 is engaged to a guide frame 4 arranged in a prescribed moving direction, and which provides wheels 9 of being moved along the guide frame 4 on the both sides. In the looper 3, plural lines of the metal strips 1 are wound, supported and passed inside one of the frame body 8 in the state of multiplex winding without mutually interfering.
