Abstract
A length measuring device for thread-like structures, especially textile threads, which are wound onto a cross-wound package or bobbin, possesses a substantially greater accuracy than heretofore known length measuring devices due to a more exact allowance for the geometric and kinematic relationships in the winding device. In particular, the slippage between the cross-wound package or bobbin and the winding drum can be taken into consideration in determining the length of the thread.
