The upper surface of the main duct 16 is provided with a large number of holes 16a for sucking air.

The filter belt 18 is endlessly stretched around pulleys (not shown) provided at both ends, and cotton wool is deposited on the surface of the main duct 16 near the hole 16a. The fly dust is scraped to one end by a scraper (not shown) that moves along the upper surface of the filter belt 5 and is removed. Immediately after that, the filter belt 5 reverses and moves to the lower side.

In this cotton fly collecting apparatus, when the shutter 22 at the entrance of the main duct 14 is opened, each sub-duct 15 corresponding to each winding unit 2 is passed from the blower 12 at the rear of the machine base 1 through the hose 13 and the main duct 14. Is sent to each of the branch pipes 15a, 15b, 15c and blown to the unwinding position of each winding unit 2.
