Abstract
A tensile yarn force sensor ( ) has a measuring member ( ), with which the tensile force of a traveling yarn ( ) is detected as a function of the measurable pressure the yarn ( ) exerts on the measuring member ( ) during winding onto a cheese ( ) at the work station of a multi-station textile machine, e.g., a winding machine or a combined spinning/winding machine. At preselectable intervals, a control device ( ) actuates cutting of the traveling yarn ( ), and triggers the performance of a zero compensation at the measuring member ( ) thereby relieved of the yarn pressure, whereby external influences on the measured result are sufficiently compensated by the zero compensation, even if the chronological sequence of bobbin changes, yarn breaks or cleaning cuts triggered by imperfections in the yarn alone do not offer a sufficient opportunity for performing the required zero compensations.
