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.

Abstract: A tire for off-the-road vehicles. The tire is designed for a removable tread, or a lugged, metal traction band. A pair of detachable resilient shields are maintained adjacent the upper sidewalls of the tire to protect this critical area of the tire from punctures.

Abstract: An apparatus for splicing two rolls of tire cord fabric in axially aligned relation. A plurality of splicing rods are forced through overlapped ends of the rolls from opposing longitudinal sides of the fabric. The splicing rods are guided through the overlapped ends at successive points spaced along parallel lines angularly disposed to the parallel warp cords of the fabric and alternately pierce and pass through the pieces of fabric from the farthest spaced faces of the overlapped ends. The splicing rods are firmly snubbed together and held in position by the coaction of the warp cords and weft threads of the fabric, as the fabric is tensioned.

Abstract: A device for sensing wet tire cord fabric treated with a liquid bonding agent carried by a vaporizable solvent. The device is characterized by a chamber in which solvent vapor is accumulated. The chamber is formed between a pair of rotatable metal rolls which engage fabric moving past them. A conventional gas analyzer is coupled to the chamber for drawing fluid from the chamber and making an analysis of the fluid to determine if the fabric is still wet and has not been sufficiently dried.

Abstract: An aircraft tire having a plurality of bias carcass plies and a pair of bead portions, each including three inextensible bead cores. All of the carcass plies in each bead portion are wrapped about the two axially innermost bead cores while the axially outermost bead core is free of any radial stresses imparted by carcass plies.

Abstract: A system for reducing the hardness of raw water to a level where it is suitable for circulation to a boiler wherein the water is converted to steam for generating power and subsequent use in equipment for building tires. The system employs, (i) a sedimentation tank in which a mixture of raw water, lime and soda ash is heated to cause the precipitation of calcium carbonate from the water as a sludge; (ii) a filter with a bed of coal for removing sludge which escapes with the water removed from the sedimentation tank; (iii) a softener with a resinous bed of sodium zeolite resin for further reducing the hardness of the water to a desired or tolerable level; and (iiii) a special filter or trap between the coal filter and zeolite softener for removing particles of coal carried along by the water as it flows through the coal filter, since the particles of coal eventually destroy the capacity and effectiveness of the zeolite softener.

Abstract: A kettle having a chamber sealed from the ambient atmosphere and designed to receive a plurality of tires retreaded with precured treads. Steam and air are supplied to the chamber in such a way that they are thoroughly mixed within the chamber to eliminate any hot or cold spots previously encountered in devices wherein the steam and air are each supplied to the chamber through a single inlet.

Abstract: A chipperless radial ply tire having its carcass ply endings wrapped axially outwardly about the bead cores and terminating along a neutral stress line and with the air impervious liner extending axially outwardly about the bead cores and completely encasing the ply endings and further including a hard chafer strip extending at least from adjacent the radially outer extremity of the bead core to about 40 percent of the section height of the tire.

Abstract: An apparatus for treating the spliced ends of a strip of white sidewall positioned on an unvulcanized tire. The unvulcanized tire is positioned such that the spliced ends of the strip rest against a resilient cushion located adjacent the inner peripheral surface of the tire. A heated pad is movable toward the cushion to compress the spliced ends of the strip together while simultaneously heating the ends to cause a crosslinking and at least a partial vulcanization of the rubber of the spliced ends to provide a highly improved splice which will not readily come apart under stress.

Abstract: A pneumatic tire and wheel assembly of the drop center type is disclosed including an inflatable annular cord-reinforced tube for filling the well of the wheel. The uninflated diameter of the cord-reinforced annular tube is substantially equal to the diameter of the base of the wheel well but expands to a diameter greater than the diameter of the bead seats upon inflation.The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawings and the following detailed description.

Abstract: A tire for a racing vehicle characterized by multiple carcass plies in which both tension and shear stresses are shared equally by the carcass plies and cord reinforcements of the plies, this being accomplished by varying the pathways and end counts of the reinforcement cords from ply-to-ply and the gauge of the plies.

Abstract: A tire with conventional components having a pair of annular beads with different diameters, and contour lengths which are substantially equal. The contour lengths are referenced to the sidewalls of the tire and are measured along the neutral axis of the carcass plies between the beads and a plane containing the mid-circumferential centerline of the tread.

Abstract: A pricker roll used with a machine for calendering reinforcement tire cords with rubber material. The pricker roll produces a pattern of cuts in the thin sheets of rubber material to allow the escapement of air entrapped in the material during the sheet-forming process.

Abstract: An apparatus for vibrating and dewebbing tire cord fabric treated with a liquid bonding agent for promoting the adhesion between the warp cords of the fabric and the rubbery material in which the cords are embedded. The fabric, freshly coated with the liquid bonding agent, is guided along a desired vertical pathway between a pair of rotating cylindrically shaped cams which are eccentrically mounted for rotation about axes which are equally spaced from the pathway of the fabric. The rotation of the cams is synchronized such that the cams continuously contact the fabric as they alternately push the fabric in opposite directions from the desired pathway to vibrate the fabric between the rotational axes of the cams. Thus, excess liquid coating is shaken from the fabric to help remove any liquid coating webbing the openings between the warp cords and weft threads of the fabric.

Abstract: A method of forming a low pressure, flotation type tire by centrifugally casting polyurethane around a network of conventional tire cords which are held concentrically about an axis to form a cylindrically shaped tire which is then mounted on a rim and inflated into the toroidal configuration of more conventionally built tires.

Abstract: A tire having a tread with a wide center groove, which is specially configured and includes a series of diamond-shaped ledges disposed end-to-end along each side of the groove intermediate the open top and enclosed bottom of the groove. At least one slot is disposed in each ledge to enhance traction when the ribs become sufficiently worn that the ledges contact the roadway.

Abstract: An elastic band for positioning around the outer periphery of a tire being X-rayed and inspected for defects. A set of Arabic numerals are spaced equally around the band for identifying the location of a defect in the tire when it appears on a television monitor used in conjunction with the system of X-raying the tire.

Abstract: A device for coiling a sheet of wire tire cord fabric under a predetermined desired tension to produce a roll of tire cord fabric which is appropriately wound free of ruffles or bagginess. The device has a take-up roll on which the fabric is coiled, a drive roll for rotating the take-up roll, and means for causing relative movement of the rolls to maintain a predetermined pressure between fabric on the take-up roll and the drive roll, as the roll of fabric increases in size and weight. An idler roll is disposed adjacent the take-up roll for first engaging the fabric, changing its directional movement and guiding it immediately onto the take-up roll. Paper is directed between annular layers of the roll of fabric to separate the fabric and prevent any distortion of it.

Abstract: A tire bead consisting of at least two cords of different materials. One of the cords is composed of aramid and the other of the cords is composed of metal for stabilizing the aramid cords and rigidifying the beads.

Abstract: A mold provided with specially configured blades for forming correspondingly configured recesses in ribs shaped in the tire tread by a number of grooves which generally extend in a circumferential direction about the tire.
