Abstract
A debris cleaning apparatus for a circular knitting machine includes a horizontal radial support arm rotatably mounted coaxially to the machine frame with a rotary paddle-type fan mounted to one outward end of the support arm for movement within a circular range of motion and a counterweight mounted to the other outward end of the support arm. A drive motor imparts circular motion to the fan either in a vertical plane or in a conical path of motion, wherein the line of force of the fan is substantially maintained out of co-planar relation with the central axis of the machine. In this manner, the moving airstream generated by the fan provides a motive force for propelling the support arm to rotate about the central axis at a cyclically varying speed of rotation, either reversingly or in a single rotational direction. Thus, the airstream is directed through its range of movement over the knitting and yarn feeding instrumentalities of the machine about its full circumferential extent to blow lint from surfaces. In another embodiment, two auxiliary fans are operated alternately to propel the support arm reversibly in opposite directions.
