ABSTRACT:
A hose built on a non-expanding, non-collapsing mandrel is removed readily lengthwise of and off the mandrel, facilitated by a tube of tough, flexible, thin anti-adherent film disposed in snug fitting contact with the length and girth of the mandrel. The tube is secured to the rigid metal member only close to the end thereof from which the hose is removed. Preferably, the tube is invaginated so as to provide inner and outer slidably juxtaposed walls. The hose built on such mandrel is moved lengthwise together with the outer wall of the tube which slides on the inner wall or the metal member. Lubrication, as by an air film, can facilitate the sliding, and does not contact the hose.
