Band-winding method

A process for winding a continuously supplied band (5) onto a bobbin (2), with the bobbin (2) being rotated and the band (5) being reciprocated along the entire length of the bobbin (2) at a winding angle (α) by means of a cross-winding device (4), wherein each time the bobbin diameter has increased by a particular value, the winding ratio, i.e. the ratio between the number of bobbin rotations and the reciprocating motion (to-and-fro stroke) of the cross-winding device, is changed in steps, wherein the bobbin (2) is driven by a separate motor (M1) and the cross-winding device (4) is also driven by a separate motor (M2) and the change in the winding ratio is performed electronically by stepwisely changing the ratio of the speeds of the two motors and that, with the stepwise change, the winding ratio is changed in essentially integral steps so that, with each change, the post-decimal point part of the winding ratio will change by 0.1 at the most.
