Abstract (en)
[origin: US4789107A] When a thread (10) supplied at a constant speed is wound onto a cross-wound bobbin (11), the variations in thread tension are compensated, and in addition predetermined thread-tension limiting values are prevented from being exceeded as a result of a change in the winding-on speed. A first regulating system (96) is provided for compensating periodic variations in the thread tension, while a second regulating system (51) is provided for compensating shifts in the range of thread tensions. The second regulating system is designed as a variable step-up gear (5), the drive part (60) of which is connected to a drive shaft (4) extending over several spooling stations. The output part (62) of this step-up gear (5) is connected to the spooling roller (3), the drive part (60) being connected to the output part (62) by means of a transmission member (61) which determines the gear ratio at any particular time and which is adjustable as a function of the thread tension. The drive part (60) and the output part (62 ) are both designed as cone wheels, between which the transmission member (61) is continuously adjustable. The transmission member (61) has assigned to it an adjustable basic position and a return device (89) for returning to a basic position determining the maximum step-up ratio.
