  • Method of diametrally expanding an elastic tube
    Patent number: 6162383
    Abstract: A method of diametrally expanding an elastic tube (6), which includes the steps of inserting a distal end portion of a expansion member (1) into an elastic tube (6), the expansion member (1) being provided at least at a surface thereof with a solidified layer of a low melting point material, and the distal end portion (4) of the expansion member (1) being tapered, a tip end of which having a diameter which is equal to or smaller than an inner diameter of the elastic tube (6), and moving the elastic tube (6) over the solidified layer to diametrally expand the elastic tube (6), the surface of the solidified layer being made into a low frictional surface due to a melting of the low melting point material.
