Wrappable protective sleeve with closure and locating feature and methods of construction and use thereof

Abstract

A wrappable protective sleeve for providing protection to at least one elongate member contained therein and methods of construction and use thereof are provided. The sleeve includes a flexible textile wall having opposite inner and outer faces bounded by opposite edges and opposite ends. The opposite edges extend generally parallel to one another between the opposite ends. A pair of adhesive layers is bonded to the inner face, with each of the adhesive layers being spaced from one another. The adhesive layers extend between the opposite ends adjacent the opposite edges. Further, a release paper is releasably adhered to the pair of adhesive layers for subsequent removal and use of the sleeve.

DETAILED DESCRIPTION OF PRESENTLY PREFERRED EMBODIMENTS

(8) Referring in more detail to the drawings, FIG. 1 illustrates a wrappable textile sleeve 10 constructed in accordance with one aspect of the invention shown wrapped about an elongate member 12 to be protected, such as a wire harness or pipe, by way of example and without limitation. The textile sleeve 10 has a wall 14 sized to be wrapped circumferentially about the elongate member 12 to be protected such that opposite, lengthwise extending edges 16, 18, which extend generally parallel to one another and generally parallel to a central longitudinal axis 20 of the sleeve 10 between opposite ends 22, 24, are brought into overlapping, fixed relation with one another. In addition to the opposite edges 16, 18 of the wall 14 being fixed in a circumferentially wrapped configuration, thereby providing the desired protection to the elongate member 12 about the entire circumference of the elongate member 12, the wall 14, as discussed further below, is fixed to the elongate member 12 to prevent inadvertent movement of the sleeve 10 relative to the elongate member 12. Accordingly, the sleeve 12 is assured of remaining in its intended protective position about the elongate member 12.

(9) The textile wall 14, as schematically shown in the Figures, can be formed by interlacing yarn or yarns with one another, including monofilament and/or multifilament yarn, wherein the interlacing can be performed to form a woven, knitted, or braided structure. In addition to interlacing yarn or yarns, the wall 14 can also be formed as a nonwoven structure. It is to be understood that nonwoven structures are formed from a web of material including intertwined, relatively short fibers via a wet or dry process. The fibers can be provided as organic fibers, such as from jute, kenaf, hemp, or any other suitable cellulosic fibrous material, and also from any suitable recycled materials and/or waste stream materials and/or from inorganic fibers, including any type of polymeric materials, including heat-meltable material, for example, as a low temperature melt polymeric material, such as fibers of polyethylene, PET or Nylon. It should be recognized that other low melt polymeric materials could be used, such as thermoplastic bi-component fibers whose outer sheath, such as polypropylene, for example, melts when heated above its melting point.

(10) Upon wrapping the wall 14 about the elongate member 12, the opposite edges 16, 18 of the wall 14 are fixed in the circumferentially wrapped “cigarette” configuration via a first adhesive layer 26 to provide the desired protection to the elongate member 12 about the entire circumference of the elongate member 12 and the wall 14 is fixed to the elongate member 12 via a second adhesive layer 28 to prevent inadvertent movement of the sleeve 10 relative to the elongate member 12. The first and second adhesive layers 26, 28 forms a pair of adhesive layers bonded to an inner face 30 of the wall 14 in spaced relation from one another, while an outer surface 32 of the wall 14, as manufactured, remains free of any adhesive or other fastening mechanism. The adhesive layers 26, 28 extend along the opposite edges 16, 18, shown as being immediately adjacent the opposite edges 16, 18, between the opposite ends 22, 24, wherein the adhesive layers 26, 28 are also shown as extending from one end 22 to the opposite end 24. With the adhesive layers 26, 28 being laterally spaced from one another, an intermediate portion 34 of the inner surface 30 is free of any adhesive. Accordingly, the amount of adhesive used in the construction of the wall 14 is minimized, and is significantly less than that if the entire inner surface 30 were covered with adhesive, and thus, the cost of the adhesive layers is greatly reduced from that if the entire inner surface 30 were covered with adhesive.

(11) In construction of the sleeve 10, to prevent contamination of the adhesive layers 26, 28 and to preserve the adhesive layers 26, 28 for future use, a release paper 36 (FIG. 3) is releasably adhered to the pair of adhesive layers 26, 28. To minimized the amount of release paper necessary, and to reduce the envelope of the sleeve 10 for shipping and storage, the wall 14 is wrapped or folded to evert the wall 14 such that the inner surface 30 faces radially outwardly and the outer surface 32 faces radially inwardly. The opposite edges 16, 18 are brought into abutting or substantially abutting relation with one another such the adhesive layers 26, 28 are immediately adjacent one another. With the adhesive layers 26, 28 immediately adjacent one another, the width (W) of the release paper 36 needed to cover the adhesive layers 26, 28 is minimized, wherein the release paper 36 can be provided having a width that is equal to, or substantially equal to the width of each adhesive layer 26, 28 combined or added together (w1+w2).

(12) In FIG. 5, a sleeve 110 formed in accordance with another aspect of the invention is shown, wherein the same reference numerals, offset by a factor of 100, are used to identify like features. The sleeve 110 has a wall 114 constructed in the same fashion as discussed above for the wall 14. The notable difference is in how the wall is wrapped or folded in use. As such, the wall has first and second adhesive layers 126, 128 spaced from one another and extending along opposite edges 116, 118 between opposite ends 122, 124. Also, a release paper, as discussed above, is applied to the wrapped or folded wall 114 to releasably cover and protect the adhesive layers 126, 128 prior to use. With regard to both walls 14, 114, it should be recognized that the overall width (extending between opposite edges 16, 18, 116, 118 and length (extending between opposite ends 22, 24, 122, 124) of the wall 14, 114 can be formed as desired, depending on the end use of the respective sleeve 10, 110.

(13) In use, as shown in FIG. 6, rather than wrapping the wall 114 in cigarette fashion about a single elongate member, the wall 114 is wrapped or folded in half about a T-shaped union 40 formed by an intersection of a plurality of elongate members, shown as a pair of elongate members 112, 112′. The T-shaped union 40 is formed by a first elongate member 112 extending generally horizontally and a second elongate member 112′ extending generally transversely to the first elongate member 112. During application, the elongate members 112, 112′ are positioned as shown in FIG. 5, with the first horizontal elongate member 112 extending across an approximate lengthwise dividing centerline 42 of the wall 114 such that the first elongate member 112 extends across the opposite adhesive layers 126, 128 in bonding relation therewith. Meanwhile, the second elongate member 112′ extends vertically along an approximate widthwise dividing centerline 44 of the wall 114 between the adhesive layers 126, 128, shown as being out of contact with the adhesive layer 126, 128. Then, the upper half of the wall 114 is folded over and about the first elongate member 112 to completely cover the T-shaped union 40 and to bring the adhesive layers 126, 128 into adhesive, fixed contact with themselves. Accordingly, each of the pair of adhesive layers 126, 128 is adapted to be adhered to a common elongate member 112 and each of the pair of adhesive layers 126, 128 is also adapted to be adhered to itself.

(14) Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that the invention may be practiced otherwise than as specifically described, and that the scope of the invention is defined by any ultimately allowed claims.
