ABSTRACT:
This invention is a device for unwinding and guiding yarn from a feed bobbin located in a feed box. The device has an arm which is rotated by the tension of the unwinding yarn. More specifically, this invention is a device for unwinding and guiding yarn which has first unwinder arm rotating around the bobbin rotatably connected to a pivot positioned above the spindle head, and a second unwinder arm rotatably connected to the spindle for producing twisted yarn. The first unwinder arm is supported by a frame which is connected to the box containing the two superposed bobbins so as to allow the second unwinder arm to rotate within the rotatable trajectory of the first arm.
