PURPOSE: An unwinding device is provided to form thickness or a pattern uniformly of fabric or knitting made in a weaving part or a knitting part by supplying the same amount of each yarn. CONSTITUTION: An unwinding device(100) includes a plurality of bobbins(20) and a pair of pressure rollers(70). A pair of pressure rollers loosen thin lines winded on a plurality of bobbins independently while pulling the lines. A rotating disc(10) is mounted on a base(B) pivotally which is driven by power of a driving motor. A plurality of bobbins are mounted on the rotating disc. The bobbins race in the center of the rotating disc. A tension control arm(30) is mounted on the bobbin pivotally. The tension control arm has a guide hole(31) opened to a vertical direction on an end. The guide hole makes the tension control detect tension load of the thin line unwound. |
