PURPOSE:To obtain the optimum characteristic of tension adjustment for a thread to be wound up by a winder without reference to the degree of the tension in a compensator to adjust the change of the tension of the thread by constructing a bar with a thread guide to be magnetically attracted by magnets. CONSTITUTION:A thread T is fed to a winding drum 5 with a traversing groove as being held between a draw-out roller 1 and a cot roller 3, and wound up on a bobbin 7 frictionally driven by the said drum 5 for forming a package 9. In this device, a compensator 11 is arranged between the above-said roller 1 and the winding roller 5 for adjusting the tension of the thread T. In this compensator 11, a thread guide member is provided at the top of a bar 13 pivoted on a machine base via a pin 15, and the bar 13 is constructed to be pulled in one direction by a draft spring 19. Besides, on the machine base, magnets 25 and 27 are provided at positions of a stopper 12 to regulate the oscillating range of the bar 13 and the oscillation limit of the bar 13. |
