FIELD: textile industry; spinning machines. ^ SUBSTANCE: invention relates to devices for making bobbins of complex threads including elastomers. In proposed device, tension of thread at outlet of stored hopper is determined depending on deviation of quantity of thread in hopper from preset quantity. Quantity of thread is determined by checking position of movable of hopper, and tension is provided by controllable tensioner so that, at decrease of thread level in hopper, tension at outlet of tensioner is increased and vice versa. ^ EFFECT: improved quality of bobbins owing to provision of preset stable tension of complex threads with elastomers at their winding on. ^ 1 dwg |
