Abstract:
1. A bobbin winding device for generating a bobbin by winding a thread or bandlet onto a bobbin core, comprising: fixing means for holding a bobbin core and rotating it around an axis of rotation (A), thread-pressing means for pressing a thread or bandlet against the peripheral surface of a bobbin that builds up on the bobbin core, whereby the thread-pressing means are movable essentially radially relative to the axis of rotation (A), with the thread-pressing means being configured as a press roll with a longitudinal axis oriented parallel to the axis of rotation (A), a traversing thread guide located close to the thread-pressing means for reciprocating the thread or bandlet along the axis of rotation (A), thread-support means for conducting the thread supplied to the bobbin or bobbin core, respectively, relative to the axis of rotation (A), wherein the thread-pressing means is movable essentially radially relative to the axis of rotation (A) together with the thread-support means so that the distance (z) between the thread-pressing means and the thread-support means will remain constant, with at least one thread deflection means configured as a curved deflection bow being arranged between the thread-pressing means and the thread-support means, which thread deflection means is movable radially relative to the axis of rotation (A) together with the thread-pressing means and the thread-support means, wherein the thread deflection means is configured as a thread-path compensating means and wherein the thread-support means conduct the thread supplied to the bobbin or bobbin core, respectively, in an axially stationary manner relative to the bobbin (A).
