摘要

PURPOSE: To automatically apply a protective film by inserting an expansible and contractible member in the protective film and bringing a contact moving member into contact with the outside of the protective film to move the film in the longitudinal direction thereof and feeding divided frame members having suction mechanisms to the end part of a double pipe and applying the protective film to the end part of the double pipe by a protective film feeding and applying means. ;CONSTITUTION: When an expansible and contractible member 56 is inserted in a protective film to be expanded, the protective film 51 is opened under tension and, in this state, a contact moving member 57 comes into contact with the protective film 51 to move in the longitudinal direction of the expansible and contractible member 56. Whereupon, the folding habit of the peripheral surface of the protective film 51 is leveled and, next, divided frame members 58 are fitted in the protective film and, simultaneously with the contraction of the expansible and contractible member, the protective film is sucked to the divided frame members 58. The divided frame members 58 are fed to the end part of a standing-by double pipe 3 by a protective film feeding and applying means to cover the end part of the double pipe 3 with the protective film 51 and this protective film 51 is heated to be bonded to the end part of the double pipe 3.;COPYRIGHT: (C)1995,JPO
