PURPOSE: To automate a winder, by causing a fluid to flow so that the moving of a fiberglass strand is guided from an upper bunching roller to the strand pinch-holding part of a pulling mechanism under a collet at the beginning of spinning.
CONSTITUTION: At the beginning of spinning-out of fiberglass, a lower gutter 41 is kept in a position as shown in the drawing, by the action of a rotary shaft 45, and a feed valve is opened so that water jets out of a water ejection tube 43. A strand S made as a result, of the spinning-out from a bushing 1 and of bunching with a bunching agent is introduced into the upper receiving part of a gutter 40 along a bunching roller 4. The strand S is then moved to the top of the guide roller 9 of a lower pulling and cutting-off mechanism through the gutters 40, 41 as the water flows down. At that time, a hold-down roller 10 is separated from the guide roller 9 and the guide roller is rotated by the turning of a cutter roller 11 so that the strand S is inserted in between the rollers 9, 10. The rollers 9, 10 are then brought into pressure contact with each other to make the strand S tense.
