The blower is driven by a clutch motor only when the machine works. And the blower can be driven without the use of the clutch motor. The motor(8) consists of a sewing machine driving clutch motor portion(9) , a blower motor portion(10), and a dust collecting box(11). A pedal(6) is established on the edge of the clutch lever(20) of the clutch motor portion(9) and connected to a limit switch(26). This limit switch is on when the sewing machine drives and off when it stops. The driving of the blower can be controlled by using a set of changing station switches.
