  • Patent number: 9745679
    Abstract: A wrappabie knit textile sleeve and method of construction thereof are provided. The sleeve includes a wall of knit yarn having opposite edges extending lengthwise along a longitudinal axis of the sleeve between opposite ends with a straightened length of the wall spanning between the opposite ends. The knit yarn includes warp yarns extending generally parallel to the longitudinal axis and weft yarns extending generally transversely to the longitudinal axis. The opposite edges are wrappable into overlapping one another to form a tubular cavity. At least one of the weft yarns is an electro-functional yarn having a straightened length that is greater than the straightened length of the wall, thereby allowing opposite ends of the at least one electro-functional member to be pulled axially outwardly from the opposite ends of the wall to form leads for attachment to a power source.

  • Publication number: 20160160410
    Abstract: A knit sleeve for providing protection to elongate members and method of construction thereof is provided. The sleeve includes a tubular knit wall having opposite end regions extending to opposite free ends and an intermediate region extending between said end regions. The intermediate region is formed as a circumferentially continuous, single knit layer and the end regions are formed having knit inner and outer layers, wherein the knit inner and outer layers inhibit the end regions from curling outwardly.

  • Publication number: 20130224408
    Abstract: A knit sleeve for an oil dip stick tube, combination thereof, method of construction thereof and method of dampening the vibration of an oil dip stick tube is provided. The knit sleeve includes a circumferentially continuous, closed knit tubular wall extending between opposite ends with a pair of end sections adjacent the opposite ends and a midsection extending between the end sections. The end sections include heat-shrinkable yarn to allow the end sections to be heat-shrunk into a fixed relation about the oil dip stick tube. The midsection includes generally rigid, circumferentially extending, non-heat-shrinkable yarn to maintain the midsection having a circular configuration about the oil dip stick tube with an annular gap extending between the oil dip stick tube and an inner surface of the midsection.

  • Patent number: 8434333
    Abstract: A knit fabric, protective sleeve and glove constructed therefrom has three knit layers knit constructed and knit to one another in a single knitting operation to provide the fabric as a single piece of knit material. The fabric includes an outer layer, an inner layer and an intermediate layer sandwiched between the outer and inner layers. The outer layer is knit with a first yarn, the inner layer is knit with a second yarn and the intermediate layer is knit with a third yarn in looped fashion about at least some of the first and second yarns to provide an integrally knit structure having three layers knit stitched together in a single knitting process.

  • Publication number: 20130040081
    Abstract: A multilayer textile sleeve and method of construction thereof is provided. The sleeve includes a textile wall having opposite edges extending lengthwise along a longitudinal axis of the sleeve between opposite ends. The opposite edges are configured to overlap one another to bound a central cavity of the sleeve. The wall has an inner layer with opposite inner and outer faces and an outer layer with opposite inner and outer faces. The inner and outer layers overlap one another and are constructed of interlinked yarn. The inner and outer layers are integrally connected to one another across interlinked portions adjacent the opposite edges by yarn common to each of the inner and outer layers.

  • Publication number: 20100084825
    Abstract: A textile gasket and method of construction thereof for establishing a seal between mating members in a high temperature application is provided. The gasket has a knit, tubular body constructed at least in part of non-metallic, heat-resistant yarns. The body extends between opposite ends with at least one of the ends being rolled toward the other end to form a circumferentially extending rolled portion of a predetermined diameter for receipt between the mating members.

  • Publication number: 20080169038
    Abstract: A wrappable heat shield for an exhaust pipe and methods of construction and installation thereor includes an outer layer of metal having opposite inner and outer faces extending between opposite sides. An inner layer of non-woven insulation is attached to the the outer layer by a crimped portion extending along one of the opposite sides of the outer layer. The inner layer has a width sufficient to extend completely about a circumference of the exhaust pipe and is arranged in continuous contact with the exhaust pipe about its circumference while the outer layer remains spaced therefrom.

  • Publication number: 20070240896
    Abstract: A protective sleeve assembly for elongate members has a tubular wall with an inner surface providing a cavity extending along a longitudinal axis between opposite ends of the sleeve. The assembly includes at least one closure member laid-in with the tubular wall, such that at least a portion of the closure member within the tubular wall is moveable relative to the tubular wall. At least a portion of the wall inner surface is constricted toward the longitudinal axis to engage the elongate member upon pulling the closure member outwardly from the wall. The sleeve is expandable radially outwardly from the longitudinal axis to allow relative axial movement between the sleeve assembly and the elongate member by pulling the sleeve wall radially outwardly.
