An interlock circular knitting machine for knitting a double-knit fabric in which multiple yarns are knit into cylinder needle and dial needle wales, by two types of cylinder needles and two types of dial needles supplied by yarn carriers with multiple yarns, and controlled by a needle selecting cam system through first and second processes which cause the needles to move between high-tucking, holding, clearing and welt positions so that two yarns are knit together into stitch loops in each wale, the stitch loops in adjacent wales in each course being knit of one yarn from the stitch loop in the adjacent wale in the same course and a yarn from a stitch loop in the adjacent wale from an adjacent course.

Apparatus for knitting a double-knit fabric having non-run and

Apparatus for removing and collecting fiber waste from a creel stand having multiple, juxtaposed creel sections including an air suction/blower blowing a first air stream across the top of the creel sections and creating a second air stream flowing across the bottom of the creel sections. An air deflector reciprocating across the top of the creel sections deflects the first air stream downwardly through the creel sections. A bottom plenum beneath the creel sections receives the air stream from the creel sections and confines and directs the second air stream to the suction/blower. A second blower blows air through the bottom plenum toward the suction/blower to assist the suction/blower in creating the second air stream. A plurality of baffles are included in the bottom plenum to provide laminar air flow therein.

A method of and circular knitting machine for producing a knit fabric having more uniform stitches including yarn feeders feeding a plurality of yarns to stitch forming instrumentalities, the spacing of which affects stitch length and which is subject to change during operation of the knitting machine, a sensor for sensing the tension in the plurality of yarns which changes with changes in the spacing of the stitch forming instrumentalities, and generating a signal indicative of the average tension in the yarns, a comparator for comparing the sensor signal with a pre-set desired tension, a convertor for converting the comparison result into a drive signal, and an adjuster adjusting the spacing of the stitch forming instrumentalities responsive to the drive signal.

Mutually spaced fiber waste collectors upon the knitting machine and creel of a knitting unit collect fiber waste which is then withdrawn by a fiber waste remover that is selectively connectable to different ones of the fiber waste collectors. Sensors detect when the fiber waste collected by the collectors exceeds a predetermined amount.

Dust collector/remover in knitting machine and its controlling method

A dust removal and collection system which includes a suction fan for creating upwardly and inwardly flowing air streams through a knitting section and a yarn feeding and guiding device for removing dust and other fiber waste from the components thereof. An airstream receiving and confining hood overlies the knitting section and defines therethrough an air passageway. An entrance end of the air passageway is disposed radially outwardly of and above the knitting section so that the upwardly flowing air stream flows outwardly of the knitting section to carry dust and other fiber waste entrained therein upwardly and outwardly from the knitting components such that no dust or other fiber waste will return to the knitting components. A waste collection device cooperates with the hood to receive and collect the dust and other fiber waste removed from the double knitting machine.

Dust and waste removal and collection system for double knitting machine

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.

Collector/remover of dust of flocks in knitting machine

Vertically stacked drive wheels (17.sub.1, 17.sub.2, 17.sub.3 and 17.sub.4) are provided above a yarn feed wheel (21) which is provided with a first yarn feed surface (27) providing comparatively high friction with the yarn engaged thereby and adaptable for use when the rate of yarn feeding varies, such as in the case of Jacquard pattern knitting, and a second yarn feed surface (28) providing comparatively low friction against the yarn engaged thereby and adapted for use when the rate of yarn feeding is constant, such as in the case of plain knitting. Manually adjustable yarn guide means (29, 30) is provided for selectively guiding yarn to the first and second yarn feed surfaces (27, 28). Clutch members (24, 24') are interposed between pairs of the vertically stacked drive wheels and are selectively operable to impart rotation to the feed wheel (21) from a selected one of the drive wheels.
