| description | The invention discloses a multi-beam yarn unwinding method. The method comprises the process that a plurality of yarns led out of beams in a one-to-one correspondence mode are unwound and unreeled through a yarn unwinding roller, and in the process, the beams are controlled to rotate forwards or reversely by measuring the tension change of the yarns, so that the yarns keep constant tension; when measuring that the tension of the yarns becomes small, the beams are controlled to rotate reversely by an angle relative to the yarn unwinding roller, and the yarns between the beams and the yarn unwinding roller are tightened, so that the yarns keep constant tension; and when measuring that the tension of the yarns becomes large, the beams are controlled to rotate forwards by an angle relative to the yarn unwinding roller, and the yarns between the beams and the yarn unwinding roller are loosened, so that the yarns keep constant tension. According to the multi-beam yarn unwinding method, the beams are controlled to r |
