  • Patent number: 5469718
    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.

    Abstract: Fiber waste generated adjacent the knitting section and the yarn feeding members of the machine is conducted by air streams into the lower end of a first duct extending upwardly from the knitting section. The air and therein entrained fiber waste passes from the upper end of the duct and then sequentially through a laterally extending second duct and a vertically extending third duct to a waste collection box. The third duct is made of flexible fabric, vinyl or similar material having therein a multiplicity of small openings that permit lateral passage of air from the duct, while restricting lateral passage of fiber waste from the duct. A funnel-shaped member within the collection box compacts the waste entering the box. The first duct has vertically aligned sections that are telescopically adjustable.

  • Patent number: 5177985
    Abstract: Fiber waste generated adjacent the knitting section of the knitting machine and adjacent yarn feeding devices of the machine is blown to a filter adjacent the top of the machine. The lint is removed from the filter by a rotatable filter cleaner and then is transported by suction to a vacuum device outside of the machine. A blower for blowing fiber waste from the yarn feeding devices is mounted upon a support ring and undergoes reciprocal movement about a path of travel defined by such ring. In one embodiment the ring undergoes rotational movement and the blowing means moves with it, while in another embodiment the ring is stationary and the blowing means moves relative to it.

  • Patent number: 5175905
    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.

  • Patent number: 5000013
    Abstract: A valve for distributing pressure air to remove lint from a knitting machine at locations where it typically accumulates, in which plural balls are normally seated in valve openings to close the flow passages to these locations and are unseated therefrom to allow the flow of pressure air when contacted by a rotating arm. Control over the movement of the ball is exercised by the seating of the ball not only in a horizontally oriented valve opening, but also in an opening of a vertical wall adjacent to the valve opening, so that the two noted horizontal and vertical openings positioned about the ball provide a desired position to the ball, and the projection of the portion of the ball through the vertical opening presents it for unseating contact by the rotating arm.

  • Patent number: 4869080
    Abstract: A knitting machine attachment using pressure air flow through, and discharging from, plural flutter tubes to control the accumulation of lint. Each individual tube construction consists of an inner circular bore and an encircling eliptical wall which causes a flutter or pivotal traverse in a specified plane or path, namely that in favor of the weaker or thinner walls of the tube. This maximizes the amount of discharging pressure air that can be directed against specific locations where lint is likely to accummulate.
