PURPOSE:To ensure the removal of dust which is carried by the scraper, by operating the shutter depending on the suction capacity of fiber collector to connect the duct to the main duct, when the scraper moves to the position corresponding to the duct. CONSTITUTION:When the scraper 7 reciprocating in the lengthwise direction along the spinning frame comes to the position corresponding to the duct 6, the shutter 11 of the duct is operated to suck the dust sticking to the scraper through the duct into the fiber collector. Simultaneously, the number of the shutters 11 to be operated is decided depending on the suction capacity of the collector. |
