Abstract:
An apparatus for continuously winding an advancing yarn onto winding tubes serially delivered to a winding position, comprisinga turret mounting at least two winding spindles having parallel axes, and means for sequentially rotating the turret so that each of the winding spindles may be alternatively moved between a winding position and a doffing position,means for traversing the yarn across a winding tube mounted on a winding spindle at the winding position and while rotatably driving such winding spindle so as to form a yarn package, said yarn traversing means comprising a grooved roll mounted on an axis parallel to the axes of the winding spindles, and a traversing unit mounted upstream of the grooved roll for laterally traversing the advancing yarn and guiding the same into the groove of the grooved roll, anda yarn transfer mechanism which is operable upon the turret moving a rotating full yarn package from the winding position to the doffing position and moving an empty winding tube to the winding position, for transferring the advancing yarn from the rotating full yarn package to the empty winding tube, the yarn transfer mechanism comprising a guide plate moveable about the circumference of the grooved roll and between an idle position removed from the advancing yarn and an operating position located between the surface of the grooved roll and the advancing yarn and so as to deflect the advancing yarn from yarn traversing means, and further comprising a yarn guide mounted for movement along a direction parallel to the axes of the winding spindles between an idle position and a catching position wherein the advancing yarn is guided into a yarn catching slot in the empty winding tube.
