Abstract
A debris cleaning apparatus (10) for a circular knitting machine (12) includes a horizontal radial support arm (24) rotatably mounted coaxially to the machine frame (14) with a rotary paddle-type fan (26) pivotably mounted to the outward end of the support arm for oscillating movement within a vertical plane. A drive motor (38) rotates the support arm and fan as a unit while simultaneously imparting oscillating movement to the fan (26) through an eccentrically driven actuating arm (56). In this manner, a moving airstream generated by the fan is directed through the range of its oscillating movement over the knitting and yarn feeding instrumentalities of the machine about its full circumferential extent to blow lint from the surfaces.
Claims11
Apparatus for removing debris from a circular knitting machine comprising:
- an upstanding shaft mounted centrally above said knitting machine,
- a support arm extending radially outwardly from said shaft,
- a blower mounted at the extending end of said support arm,
- means for rotating said support arm about said shaft, said rotating means being disposed at said shaft in drive connection therewith, and
- means for oscillating said blower through a predetermined range of motion within a generally vertical plane of movement simultaneously with said rotating means for directing a moving airstream over a predetermined area of said knitting machine to blow debris therefrom and limit debris accumulation thereon.
