Abstract
A circular knitting machine has a needle cylinder and loop-forming instrutalities which form loops along an annular loop-forming zone. A plurality of suction nozzles orbit about the annular loop-forming zone collecting dust and fluff therefrom. The suction nozzles are mounted on a rotating, annular, upper part of a channel-defining housing which rides on a stationary, annular lower housing part, the rotating and stationary housing parts together defining a suction channel with which the suction nozzles communicate, the suction channel being connected to a suction source. The annular channel-defining housing encircles the needle cylinder and is located radially outwards of and lower than the annular loop-forming zone of the circular knitting machine, the suction nozzles extending upwards from the annular rotating housing part to the annular loop-forming zone, with their ends being provided with suction openings which are located radially outwards of and facing the annular loop-forming zone.
