Abstract:
A winding machine for winding on a continuously fed yarn to form bobbins alternately on a respective tube including a yarn catch region, comprising:a stationary head yarn guide;a revolver member;a first driven winding spindle being mounted on said revolver member for carrying the respective tube;a second driven winding spindle being mounted on said revolver member for carrying the respective tube;a traversing device;a contact roller;a pivotal arm being designed and arranged to be pivotable about a stationary axis into a gap between one of the bobbins and an empty tube being located on one of said winding spindles;a first yarn guide being movable in the direction of said winding spindles and being designed and arranged to position the yarn relative to the yarn catch region of an empty tube being located on one of said winding spindles, said first yarn guide being arranged on said pivotal arm;a second yarn guide for the end of the yarn running onto a full bobbin on the other one of said winding spindles, said second yarn guide being arranged on said pivotal arm;said first and second yarn guide being designed and arranged such that in operation said first and second yarn guide, said traversing device, said contact roller and said winding spindle carrying the empty tube are located on the same side of the yarn in such a mutual relative position that after a pivotal movement of said pivotal arm carrying said first and second yarn guide into the gap the yarn does not contact the empty tube and said traversing device; andsaid first and second yarn guide being designed and arranged such that during a return pivotal movement of said pivotal arm under the effect of said head yarn guide and said first yarn guide the yarn still contacts the first yarn guide and the yarn gets in contact with the yarn catch region of the empty tube with an increase in the wrapping angle therearound.
