COMPUTER ANALYSIS DISTRIBUTION OF THE YARN LINEAR DENSITY FROM OPEN END SPINNING MACHINE

Abstract Basing on a detailed kinematics scheme of the R1 Rieter rotor spinning machine, calculation of spectral characteristics of yarn made on the spinning machine was done. The calculations served to create a computer programme facilitating the qualitative evaluation of the spinning process on the R1 spinning machine. It also allows a rapid localising of mechanical damages and technological errors in the machine. The calculations make it possible to detect the sources of periodical faults and damages of yarn which follow from: the noncentred work of elements of the spinning machine or from their being damaged, from damaged pulleys, gear wheels, driving belts, from dirt or damages of the elements driving the roller etc.
