PURPOSE:To provide the titled cleaning system where a common line shaft for driving by revolution many impellers for suction air generation within a duct having opening ports for suction air is brought to state so that the number of revolutions reaches a specified value or smaller, at this point the operation of the spinning machine is stopped, thus preventing yarn breakage from extending to many spindles as if chain reaction occurred. CONSTITUTION:A duct having opening ports for suction air is set up on the base of a spinning machine 1 along its loner direction many impellers 18 for suction air generation are provided within this duct, being connected to a common line shaft 15 and driven by revolution with a single driving source. An adsorption net 9 is provided on the periphery of the duct so as to cover each open port. The end of the line shaft 15 is fitted with a tachometer 21, and when this tachometer indicates such number of revolutions as to be a specified value or smaller, the operation of the spinning machine is ensured to stop. |
