Abstract:
An apparatus for winding an advanced yarn onto a bobbin tube to form a yarn package, comprisinga revolver mounted for rotation about a central axis and having a circular perimeter,a revolver drive for rotating said revolver about said central axis,at least one winding spindle adapted for coaxially mounting a bobbin tube thereon,carrier means mounting said at least one winding spindle to said revolver so as to be rotatable about an axis parallel to and laterally offset from said central axis and for movement in an essentially radial direction with respect to said central axis between a first radially outer position which is radially outside the perimeter of the revolver and a second radially inner position which is radially within the perimeter of the revolver,a spindle drive mounted to said carrier means for directly rotating the at least one winding spindle,a pressure roll mounted so as to engage with an abutment force the circumferential surface of the package being wound on the bobbin tube mounted on the at least one winding spindle, andcontrol means for independently controlling the revolver drive and the movement of the carrier means, such that the direction of movement of the at least one winding spindle away from the pressure roll can be changed during the build of a package on a bobbin tube mounted on the at least one winding spindle, to thereby change the abutment force between the pressure roll and the package.
