PURPOSE: To stably supply a screw thread by parallelly providing two rotating rollers in a rotary hopper having a stirring means and arranging a straightening brush and a scrape-off plate in the upper so as to straighten the screw thread.
CONSTITUTION: Rotating a motor 17, it rotates two parallel rollers 21 while a roller 20, belts 22, 23, transmitting roller 24, shaft 25 and a roller 11, and also a hopper 10 rotates. Accordingly, a screw thread in the hopper 10 is scooped up by a stirring plate 12 and dropped down onto the rollers 21. This screw thread, which receives the action of the rotating rollers 21 further receives even the action of a straightening brush 33, is straightened. And scraping off unstraightened or surplus screw threads by a scrape-off unit 31 from above the rollers 21 into the hopper 10, only the straightened screw thread is supplied. By this constitution, supply of the screw thread can be stably attained.
