Covering Or Wrapping Patents (Class 57/3)
  • Patent number: 6321519
    Abstract: Wire, or other material, is wrapped around a shaft as the shaft turns, producing a coil. After being slid off the end of the shaft, the coil can be re-coiled by repeating the process. By shaping the twice-coiled material, a variety of pleasing jewelry beads may be formed. A variety of jigs useful for performing process are disclosed. One jig is easily and inexpensively manufactured from a unitary length of small rod, bent to provide (a) a wrapping shaft, (b) a feature for securing a free wire end; and (c) an actuator handle. The novel principles can be implemented in many different embodiments.

  • Patent number: 6318060
    Abstract: A method and device for the production of core yarn (63), whereby a core yarn (12) is brought to a fiber slubbing (8) which has been refined in a drafting system before said slubbing is reinforced by twisting. The core yarn (12) is embedded in covering fibers. The fiber slubbing is compressed in a compacting device (22) after the core yarn (12) has been brought to the slubbing and before twisting occurs.

  • Patent number: 6260342
    Abstract: A machine is provided for forming a decorative twisted spiral garland from at least one continuous ribbon web, and a pair of continuous wires. One or more ribbon webs are guided to the outside of a pair of elongated threaded rods which are respectively disposed on opposite sides of and generally parallel to a main axis. The rods form part of a loop frame which is rotated about the main axis to wind the ribbon webs around the rods in a series of continuous loops and draw the webs from supply reels, while the rods are simultaneously rotated about their own axes to advance the ribbon loops along the main axis. A wire supply rotates in synchronism with the loop frame, guiding a pair of wires into paths respectively on opposite sides of the ribbon loops and thence along the main axis between pinch rollers for pulling the wires longitudinally along the axis. The rotation of the wire supply twists the wires and the ribbon loops to form the garland.

  • Patent number: 5927059
    Abstract: An exemplary apparatus is a jig including a chuck having a plurality of radially movable members for controllably gripping a member inserted in an axial bore extending therethrough. The chuck is mounted on a hollow tube whose axis is collinear with the bore of the chuck. This jig is used by first positioning a first elongated member (e.g. a first, or "inner" wire) in the axial bore of the chuck, and tightening the radially movable members thereon. The distal end of a second elongated member (e.g. a second, or "outer" wire) is secured in a fixed relationship with the chuck, so that the distal end turns with the chuck. The chuck is then rotated so as to rotate the first, inner wire. As this inner wire is rotated, the operator trains the second wire thereagainst, thereby yielding a length of coil with the inner wire extending therethrough.

  • Patent number: 5638669
    Abstract: A method for manufacturing a twisted yarn includes the step of removing two rovings from two separate supplies and passing each roving through a separate drawing device. From each roving a separate spun yarn is produced by ring-spinning. Each spun yarn is collected in the form of a bobbin on a yarn carrier of separate hollow spindles, wherein the separate hollow spindles are positioned atop one another. With formation of a yarn balloon the spun yarn is withdrawn from the bobbins and guided through the hollow spindle axle of the respective hollow spindle. The spun yarn withdrawn from the upper one of the hollow spindles is guided through the hollow spindle axle of the lower one of the hollow spindles. Both spun yarns are then guided together to a winding device positioned below the lower one of the hollow spindles. The hollow spindles are rotated as a function of the winding speed of the winding device such that a twist of the spun fibers is at least partially canceled.

A stabilizer mechanism is provided for a flywheel disposed coaxially with the product reel, and a torque differential device is coupled to be driven by the reel and to drive the flywheel in a direction opposed to the rotational direction of the reel, wherein any change in the angular momentum of the reel is opposed by a change in the angular momentum of the flywheel.

  • Patent number: 5259180
    Abstract: A cabling machine is disclosed for laying optofibers, cables or the like in an oscillating, wavy path around a smooth pull-reliever, or into grooves having an oscillating, wavy shape which are extruded around a pull-reliever, i.e., so-called S/Z-cabling. The machine includes an S/Z-bench (6) which includes an aligning mechanism (13) which grips and guides the pull-reliever (2), and a motor (15) which imparts an oscillating, rotational movement to the aligning mechanism via a transmission (14). When used with a grooved pull-reliever (2), a laying-on tube (11) of the S/Z bench (6) is connected to the transmission (14) and a sensor (17) is connected to the transmission and functions to detect rotation of the laying-on tube (11) caused by the oscillating waveshape of the grooves. A reeling-off device (1) and a braking capstan (3) of the machine then cause the pull-reliever (2) to rotate to perform a corrective function.

  • Patent number: 5183442
    Abstract: A double helix is formed from two partial helices each having the same winding direction and each having an oval cross-section with nearly straight upper and lower winding legs. The facing winding arcs of the two partial helices encircle each other. The upper winding legs of the partial helices extend at a different angle with respect to the longitudinal axis of the partial helices than the lower winding legs of the respective partial helix. The upper winding legs of one partial helix extend at the same angle with respect to the longitudinal axis as the lower winding legs of the other partial helix and vice versa.

  • Patent number: 5111646
    Abstract: A device for winding tape around a continuous strand of material, for example a cable, wherein two reels of tape (11, 12) are mounted on a rotating tape feed device (1) via individual reel carriers (13, 14) which rotate independently and coaxially with the strand of material, so that each empty reel of tape can be stopped, exchanged, and brought back into operation while the tape feed device (1) is still rotating. The tape can therefore be placed around the strand of material without the device being stopped. In order to change the reel of tape, it is only necessary to reduce the rotational speed of the tape feed device (1).

  • Patent number: 5075952
    Abstract: A method of cladding a reduced diameter portion of a cable wherein the reduced diameter portion is created by grinding the external surfaces of the cable. The cladding is placed around the reduced diameter portion of the cable and is likewise reduced in diameter by rolling, hammering, or other external force. In this manner, a cable cladding can be accomplished without adversely effecting the flexibility of the length of cable.

  • Patent number: 4887422
    Abstract: This invention provides a composite wire rope comprising a plurality of outer strands laid helically about a helically stranded core. The core is comprised of high strength synthetics, such as polyamide or polyolefin materials to form a unitized lay central member. The method for forming the rope comprises the steps of twisting high strength synthetic monofilament yarns into core elements to provide a high degree of stability and overall tensile strength. Each such element is helically laid in a single operation to form the finished core. Lubricant may be applied and subsequently a protective jacket of steel, natural or synthetic material may be provided to encapsulate the core and lubricant. The rope structure is completed by helically laying a plurality of outer strands about the core.

  • Patent number: 4856266
    Abstract: A plurality of grooves are formed in an outer surface of a spacer. The grooves are formed continuously in the longitudinal direction by a die which surrounds the circumference of the spacer. The grooves extend, in the form of parallel periodically reversing helices along the longitudinal direction of the spacer. The optical fibers are guided into the grooves through guide plates arranged to rotate in a reciprocating motion about the spacer. The position of the grooves is detected and converted into an electric signal. The operation of an actuator for driving the movement of the die and the guide plates is controlled on the basis of the electric signal thereby rotating the plates and the die in synchronism with displacement of said grooves.
