Abstract
Coil changing device for inserting new coil sleeves into a bobbin frame of a cross-wound bobbin winding device, including a friction wheel drive having at least one friction wheel for frictionally driving the coil sleeve and a support for the at least one friction wheel, the at least one friction wheel having a longitudinal axis and being slideable on the support in direction of the longitudinal axis.
Claims5
Coil changing device, comprising a cross-wound bobbin winding device having a bobbin frame for receiving coil sleeves to be wound, and a winding roller for driving a coil sleeve in said bobbin frame;
- and a coil changing device being movable to said bobbin winding device for inserting a new coil sleeve in said bobbin frame, and coil changing device including a friction wheel drive having a support and at least one friction wheel being carried by said support, said at least one friction wheel being driveable by said winding roller for frictionally driving the coil sleeve in turn, and said at least one friction wheel having a longitudinal axis and being slideable on said support in direction of said longitudinal axis for axially moving the coil sleeve when changing coil sleeves.
