  • Apparatus for forming dielectric optical waveguide cables
    Patent number: 4224787
    Abstract: Apparatus for winding tape around an elongate core comprises a frame structure which supports one or more reels of tape. The frame structure carries a bobbin which is rotatable with the frame structure about the core. Tape passes from the reel to the bobbin and extends between a pair of contacts before passing through a slit to the core. The contacts are normally open but if the tape touches one of these that contact closes and the speed of the motor, which drives the frame structure is adjusted to maintain the tape between the contacts. This arrangement ensures a substantially constant pitch of the tape around the core.
