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.
Claims8
Apparatus for winding tape around an elongate core comprising a frame structure rotatable about an axis, said structure defining an axially extending passage for said core to pass along, a bobbin carried by structure and mounted so as to be rotatable about the path of said core, means for mounting a reel of tape on said structure and means for guiding tape from said reel to said bobbin, said bobbin including a pair of spaced sensors between which the tape is arranged to pass, said sensors being connected to control circuitry for drive means for said frame structure, said control circuitry being operative to control the drive means such that the tape is maintained between the sensors.
