PURPOSE: Water drops splashed from the yarn that is being reeled are collected, sericine and cotaminations are removed from the water and the resultant clean water is fed between the shaft of the revolving type yarn collector and the rotor, thus preventing the adhesion of sericine or other contaminations to the shaft to ensure the smooth rotation.

CONSTITUTION: Filaments from cocoons are collected and passed through the hole in the shaft 2 to form a yarn 3. Further, the yarn 3 is passed through collector 4 and drum wheels 5, 6 and the yarns 3a and 3b form a kennel. When the yarn is passed through a coil guide 7 and taken up around a reel 8, the water drops on the surface of the yarn 3 are splashed when yarns 3a and 3b are twisted and simultaneously sericine and contaminations are scattered as well. A rotor composed of blade 9 and pulley 10 is loosely inserted into a shaft 2 and the shaft 2 is fixed to the mounting metal 13. A water tank 18 is fitted to the plate 12 so that the cut for water feed 16 is opposed to the water outlet 15. Splashed water drops containing sericine and other contaminations is introduced into the water tank 18 when sericine and others are removed by precipitation and clean water is always sent to the rotor.
