  • Patent number: 4134384
    Abstract: A rotatable sleeve for guiding at least one strand of wire, for example, includes a tubular outer member bonded to a tubular, dimensionally stable inner member which is press fitted onto a rotatable shaft. Dimensional stability is imparted from the inner member to the outer member which undergoes radial stress from the wire strand. For spacing a plurality of wire strands at a predetermined distance from one another, grooves are machined into the outer member of the rotatable sleeve. A further feature provides another tubular member inside the inner member for optimizing the press fit of the rotatable sleeve to the shaft.
