Abstract:
A method for producing a sound-absorbing material in a cable reel, which cable reel comprises a stationary member assembly and a movable member assembly rotatably mounted on said stationary member assembly, said stationary and movable member assemblies defining a cable containing chamber having an annular configuration and upper and lower bearing surfaces, said cable containing chamber accommodating a flat cable in a coiled manner between said upper and lower bearing surfaces, opposite ends of said flat cable being led out from said stationary and movable member assemblies through electrical means, said sound-absorbing material being disposed on at least said lower bearing surface of said cable containing chamber, comprising the steps of:applying a liquid rubber or resin mixed with a foaming agent as three or more straps which extend radially and are equally spaced in a circumferential direction to said bearing surface;heating said liquid rubber or resin at a given temperature; andfoaming said rubber or resin to project said rubber or resin over said bearing surface, thereby forming said sound-absorbing material in said cable reel with an arched upper surface on each of said straps.
