Abstract: A yarn winding machine for winding an advancing yarn to form a yarn package which is formed on a driven winding spindle that is mounted in a projecting manner on a rotatable revolver. The package is engaged on its circumference by a pressure roll which exerts an abutment force on its surface. The winding spindle is supported on a mobile carrier which is mounted on the revolver. During the build of the package, the axial spacing between the package and the pressure roll is changed as a result of an evasive movement, it being possible for the evasive movement to be accomplished in several stages by the movement of the carrier while the revolver is fixed, or by the rotation of the revolver while the carrier is fixed, and so that the abutment force exerted by the pressure roll can be changed.

Abstract: An automatic spool-changing system for textile machines with an array of high-speed winding heads, for example of the type having a spool revolver and a lossless thread transfer device. The system has a conveyor moving along the machine front and a spool changer with a gripper movable between the conveyor and a spool holder in a spool-changing position. The conveyor is located below and in generally the same vertical plane with the spool holder, and the gripper, which is arranged for both rotation and axial translation, is mounted for movement along a three-legged spool doffing and spool-donning path extending forwardly of the machine front. Two embodiments are shown. In the first, a separate empty-spool magazine is provided and the conveyor merely serves to carry away the empty spools.
