  • Patent number: 4703632
    Abstract: The lint removing apparatus of the present invention is provided with at least one air jet ejecting pipe which is supported for rotation in a circular path of travel so that air is directed over and against selected portions of the knitting machine. Means is provided for supporting the air ejection pipe for rotation and drive means interconnects the rotary needle cylinder with the air ejecting pipe for rotating the air ejecting pipe in the same direction as the needle cylinder and at a decreased speed relative to the rotational speed of the rotary needle cylinder. The drive means includes a planetary gear system including a plurality of bevel gears and a bearing housing supporting the bevel gears. The bearing housing includes a lower rotatable body tube and an upper nonrotating cap.

  • Patent number: 4691536
    Abstract: The waste fiber removing device of the present invention is provided with at least one air jet nozzle and a fluttering motion is imparted to the free outer end of the air jet nozzle so that the air is directed over a relatively wide area of the knitting machine. The air jet nozzle is either stationary or may be rotated to prevent the accumulation of lint on various adjacent parts of the knitting machine. The fluttering motion of the air jet nozzle is preferably accomplished by forming the area adjacent the free end of an elastic or other type of flexible material. Various types of adjusting devices are provided for limiting the fluttering motion of the air jet nozzle so as to vary the area of the knitting machine against which the air is directed to blow away lint and the like.

  • Patent number: 4312195
    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.
