Uticaj brzine šivenja i debljine tkanine na parametre formiranja boda na šivaćoj mašini

Abstract

The paper investigates the effect of the sewing speed and fabric thickness on the sewing thread tension and presser foot displacement. Data collection devices were developed for the acquisition information regarding the thread tension and presser foot displacement during the stitch formation. A software program was created to provide on-line information and data analysis. It was shown that the increase of the fabric thickness and the increase of the sewing speed increase the sewing thread tension. The difference is most expressed at the point of the thread take-up lever highest position in the stitch forming cycle. The increase of the sewing speed and fabric thickness increases the maximum presser foot height. There is a difference in the presser foot displacement shape and timing between the lower and the higher sewing speed.
