    摘要: A method for closing the opening of each of the through-holes in the pipe-wall of a resin pipe and which extend parallel to the axis of the pipe, the method comprises pressing one end portion of the pipe in the direction parallel to the axis in a mold for closing the opening, the mold being connected to a high frequency current source, and heating the end portion by applying a high frequency current to the mold so as to melt the hole-partition walls which partition the through-holes, and the inner surface of the through-holes, thereby closing the opening.

    摘要: A method and apparatus for fusing and shaping the end of a rope, cord or the like made of heat fusible fibers avoiding the enlarged or bulbous end which normally occurs when heated in a conventional manner. The method involves inserting the cut end of a rope into a cavity of a member wherein the cavity tapers inwardly in a direction from an open end thereof to a closed bottom end, heating the member to melt the end of the rope thereby fusing together the strands and cooling the heated end of the rope to set the fused ends and shape the same to the internal shape of the cavity. The apparatus is a thin-walled, metallic member conically shaped and located at the end of a handle. A flared sleeve is also provided in which the end of the rope to be fused is inserted to compress the strands together before being heated. The conical member maybe heated by a butane torch or the like or alternatively, an electric resistance heating element maybe incorporated in a stem projecting from the handle.
