PURPOSE:To remove surely dust and fly waste attached to detaching bottom rollers, by bringing a clearing roller into contact with the outer peripheral faces of the detaching bottom rollers in such a way that it is subordinately rotatable, bringing a comb to suppress revolution of the clearing roller in one direction into contact with it under pressure. CONSTITUTION:The clearing roller 14 is brought into contact with the outer peripheral faces at the bottom of the detaching bottom rollers 11 under pressure. The detaching bottom rollers and the detaching top rollers 10 at the upper side keep the silver F between them. The clearing cloth 20 is set on the outer periphery of the roller 14. The comb 22 is brought into contact with the bottom of the roller 14 under pressure in such way that the tip of the comb and the tangent of the clearing cloth 20 made an acute angle. Consequently, the clearing roller 14 is subordinately rotated with the bottom rollers 11 in the P direction, but rotation of the clearing roller in the Q direction is suppressed, slip is produced in the rollers 11 and 14, so that dust and fly waste on the periphery of the bottom rollers 11 are transferred to the clearing roller 14. They are released by the comb 22. |
