Abstract: A method and apparatus for winding an elongate member, such as a strip or wire, under tension around a body comprising a frame maintained at a preset distance from the body and movable around the body by means including a belt held against rotation relative to the body and two belt engaging members each selectively adapted to be clamped against and released from the belt. One of the belt engaging members is fixed relative to the frame and the other of the members is movable relative to the frame in a first direction when the one member is engaged with the belt and in the opposite direction when the other member is engaged with the belt to move the frame relative to the body. The frame carries a guide for guiding the elongate member onto the body and a mechanism for tensioning the strip as it is wound on the body.

Abstract: Apparatus for winding at least one strip of an elongate product, such as a wire or ribbon, on to a cylindrical body from a spool of the product comprising means for producing relative rotation of the spool around the cylindrical body, a main drive unit for driving the rotation producing apparatus and connected to the axle of the spool through a differential driven by a secondary drive unit for braking the spool to tension said product. The secondary drive unit may be controlled by the output of a tension sensing mechanism sensing the tension of the product.
