INFLUENCE OF COCOON SHAPE ON THE DYNAMIC FORCE OF THE COCOON THREAD COMING OUT OF THE SHELL

the article analyzes the shape of cocoons, which influences the technological process of their unwinding. In order to develop, depending on the tension of the cocoon thread on the shape of the cocoon for experimental studies used spherical and oval cocoons of medium caliber without interception and with interception of the varietal mixture of the hybrid Ipakchi-1 x Ipakchi-2. To determine the dynamic force of the cocoon thread coming off the shell, the cocoons of selected samples with a set degree of interception were unwound on a single unwinding machine equipped with a strain gauge system at a speed of 85 m/min. During unwinding, the thread tension was measured and the number of breaks was counted, and it was revealed that the shape of the cocoon affects the unwinding performance.
