Abstract:
The invention concerns a method and apparatus for covering a core yarn with a cover yarn, the apparatus comprising a mounting for a package (44) of core yarn (42) which is held against rotation, first and second discs (38, 80) arranged above and below the package (44) and means (28, 74) for rotating the discs at the same speed and in the same direction. The apparatus includes also a mounting (12) for a package of cover yarn (14) and take-off means for leading cover yarn from the package to the centre of the first disc (38) after which it is guided to the periphery of the first disc and from the periphery of the first disc past the side of the core yarn package to the periphery of the second disc, the cover yarn then being guided to the centre of the second disc at which point it is brought into contact with the core yarn (42) which has been removed from its package and guided along the axis of the package, through the centre of the second disc, whereby cover yarn is wound around the core yarn, the covered yarn then being drawn off by draw off means (86, 88, 90).
