  • Patent number: 5600973
    Abstract: Process and machine for manufacturing elastic bands with small diameter tubular fabric knitting machines of the single-feed type with fixed needle cylinder and revolving cam drum, wherein a bobbin holder of an elastic thread is autonomously supported above the needle cylinder and coaxial with respect to the needle cylinder. The revolving drum has a taking arm which guides the elastic thread and the inelastic thread without mutual contact up to the immediate vicinity of the needle cylinder. A sensor detecting the diameter change of the elastic thread cylindrical bobbin is operatively connected to a driving device with regulated speed control which keeps constant the elastic thread feed. The tubular bands obtained are knitted bands with at least one inelastic thread and at least one bare elastic thread.

  • Patent number: 5520018
    Abstract: A knitting machine is described for knitting rows of yarn loops in a helical pattern around the inner core of a hose. The machine comprises at least two concentrically disposed tubes. The first tube rotates concentrically around a straight axis along which the inner core of a hose moves towards an opening in a knitting head. The first tube carries a plurality of needles and needle guides which are equally spaced from, and around, the opening in the knitting head. The second tube concentrically rotates independently around the first tube and carries, i) at least one yarn deck, ii) cams which reciprocate the needles when the first and second tube differentially rotate, and iii) the knitting head. A stationary third, rigid, hollow inner tube can be concentrically disposed within the first tube to guide the inner core to the knitting head.

  • Patent number: 5309738
    Abstract: A system for feeding a plurality of strands of material such as yarn, in unison, along an array of separate feed paths that extend from a bank of supply packages to a knitter head utilizes a bank of positive drive units that are arranged in an array that extends about the knitter head to coordinate and uniformly tension such strand reaches as extend from the positive drive units to the knitter head. The feeding of the strands takes place while the bank of supply packages, the bank of positive drive units, the knitter head and the array of feed paths all are rotated about an axis that extends substantially centrally among the rotating feed paths. Each feed path has a first reach that extends from a separate supply package to the capstan of a separate one of the positive drive units, a second reach that is wrapped around the capstan of its positive drive unit, and a third reach that extends from its positive drive unit to the knitter head.

  • Patent number: 5211034
    Abstract: A feeding cylinder (210) feeds a corresponding roving or top of fibers to be opened using a rotating card (206) which separates the fibers of the roving, and supplies them to a conveying cavity (214). A yarn guide (244), feeds tying yarn to a knitting machine capable of forming a tubular knitted manufactured article, and is arranged around a neck (240) for discharge of the opened fibers. Needles (256), during working, are also external to said neck.

  • Patent number: 4781039
    Abstract: A knitted covering for a core, e.g. of hose or electrical cable or the like, is constituted as a circular warp knit in which each of a single system of warp yarns jumps over at least one and less than all of the wales of the system in passing from course to course. A method of making the knitted core covering is also described.

  • Patent number: 4513042
    Abstract: A nonflammable sliver knit high pile fabric. The backing fabric is knitted from a flame retardant aramind spun yarn, the pile fibers are composed of a mixture of flame retardant rayon fibers and superwashed wool fibers and the back coating is constituted of a flame retardant composition. The fabric not only is flameproof, but it does not react to a flame by melting. It has good thermal insulation properties and is stable against shrinkage. The fabric is especially useful in the manufacture of wearing apparel intended for use in extreme environments, such as fire fighting and cold weather military operations.

  • Patent number: 4017949
    Abstract: The invention contemplates a scouring-pad construction wherein an outer tubular envelope is inside-out loosely knitted around a loosely fabricated pliant stuffer material, given lengths of such materials being secured to establish end closure along generally transverse alignments. In a preferred form, the inner and outer materials are both knitted, and thermoplastic filament is an important component of both knits, the ends being heat-sealed for permanent closure by local fusion of such filaments.

  • Patent number: 4003220
    Abstract: A circular knitting machine of the type providing a reinforcement of knit tubular fabric for flexible hose including a plurality of circumferentially spaced, vertically reciprocating needles. A yarn guide holder is rotatable with the machine relative to the knitting needles and carries vertical supports for connection of a hold down ring. The hold down ring including a needle guide portion affixes to the yarn guide holder and is vertically adjustable relative to the yarn guide holder for gap adjustment purposes. The hold down ring and the needle guide portion is rotated by the machine relative to needles simultaneously with the rotation of the yarn guide holder in a manner to assure even wear upon the needle guide portion which may be caused by repeated contacts by the knitting needles.

  • Patent number: 3977214
    Abstract: In a circular knitting machine of the type designed to knit a tubular fabric, a plurality of circumferentially spaced knitting needles are reciprocal in an inclined mode between a latch clearing position and a stitch forming position. The needle cylinder is provided with circumferentially inclined slots or grooves within which the knitting needles reciprocate in angularly offset relation from the vertical. Cam rings forming the cam track are rotated in a horizontal plane upon operation of the knitting machine to reciprocate the knitting needles in their angularly offset orientation.
