Is reciprocated in a state of contact with the top clearer cloth 33, and the fibers attached to the top clearer cloth 33 are scraped off by the scraper 43. The fiber scraped off from the top clearer cloth 33 is guided by the guide member 58 to a position where it does not interfere with the roving R, and then drops from the guide member 58 and is adsorbed on the filter 9 by the action of the suction airflow F1.

The brush 18 is always disposed in the operating position where it contacts the filter 9 at the end opposite to the position where the suction removing device 25 of the roving frame 1 is provided, as shown by the solid line in FIG. I'm waiting. Then, when a predetermined time has elapsed after the operation of the machine, the motor 14 is driven to rotate forward, and the brush 18 starts moving toward the suction removing device 25 integrally with the support 13 as the belt 17 moves. With the movement of the brush 18, fly waste, fiber debris and the like adsorbed on the filter 9 are scraped off, and the suction removal device 25 is removed.
Is transported to the end of the machine base where the is disposed. When the brush 18 has moved to near the end of the machine base, the operation of the suction removing device 25 is started. When the brush 18 reaches one end of the machine base, the handle 18a is engaged with the stopper 26, and in this state, the support 13 continues to move in the same direction. As a result, the link 19 is rotated counterclockwise in FIG. 3 against the urging force of the tension spring 22, and when the link 19 is rotated to a certain angle, the force of the tension spring 22 causes the link 19 to rotate counterclockwise. The link 19 is turned upside down and the engagement projection 19
Is rotated to a position where it engages with the stopper pin 21 and held at the same position, so that the brush 18 is separated from the filter 9.

When the reversal of the link 19 is completed, the motor 14 is driven in reverse by a detection signal of a proximity switch (not shown), and the brush 18 is moved together with the support 13 toward the other end of the machine base in a state where the brush 18 is held at the retracted position separated from the filter 9. Move. When the brush 18 moves to the other end of the machine base, the handle 18a engages with the stopper 27, and the support 13 continues to move further in this state, whereby the link 19 is turned clockwise in FIG. The brush 18 is arranged at an operating position where it contacts the filter 9. When the reversal of the link 19 is completed, it is detected by the proximity switch, the drive of the motor 14 is stopped by the detection signal, and a series of operations is completed. In addition, the timer starts counting in response to the detection signal of the proximity switch, and the reciprocation of the brush 18 is performed in the same manner as described above due to the time-up.

The present invention is not limited to the above-described embodiment. Instead of the suction removing device 25 which constitutes removing means for removing fly and the like on the filter 9, the present invention is concentrated at the end of the machine as shown in FIG. A cotton box 59 is provided, and the cotton swabs, etc., which are scraped off from above the filter 9 by the brush 18 and conveyed, are collected by the cotton box.
