BRIEF DESCRIPTION OF THE DRAWINGS
[0017] These and other aspects, features and advantages of the present disclosure will become more readily appreciated when considered in connection with the following detailed description of presently preferred embodiments and best mode, appended claims and accompanying drawings, in which:
[0018] Figure 1 is a perspective view of a protective sleeve having a circumferentially continuous, seamless wall in accordance with one aspect of the disclosure shown fixed about an elongate member to be protected;
[0019] Figure 2 is a perspective view of a protective sleeve having a wrappable wall in accordance with another aspect of the disclosure shown fixed about an elongate member to be protected; and
[0020] Figure 3 is an enlarged cross-sectional view taken generally along the line 3-3 of Figure 1.
DETAILED DESCRIPTION OF PRESENTLY PREFERRED EMBODIMENTS
[0021] Referring in more detail to the drawings, Figures 1 and 2 illustrate sleeves 10, 10’ having a circumferentially continuous, seamless wall 12 and a wrappable wall 12’, respectively, for routing and protecting an elongate member 14, such as a cable, wire harness, or tube, by way of example and without limitation. The elongate wrappable wall 12’ has opposite inner and outer free sides or side edges, also referred to simply as edges 16, 17, extending generally parallel to a central longitudinal axis 18, while both walls 12, 12’ extend between opposite open ends 19, 20; 19’, 20’, respectively. The opposite edges 16, 17 of the wrappable wall 12’ can be biased into overlapping relation with one another in "cigarette wrapped" fashion, such as via a heat-set formed in yams of the wall 12’, to fully enclose the elongate member(s) 14 within a central cavity C of the sleeve 10’. The walls 12, 12’ have an innermost face or surface, also referred to as inner surface 21, 21’ and an outermost face or surface, also referred to as outer surface 23, 23’, wherein the cavity C is defined and bounded by the innermost surface 21, 2 . The walls 12, 12’ are formed of interlaced yam(s) 25 (shown in separate partially broken away areas of FIGS. 1 and 2, wherein the yam(s) 25 can be woven, knit or braided, as shown, wherein it is to be understood that the illustrations shows the different mechanisms for interlacing the yam(s), however, only one is performed for any one sleeve), which can include monofilaments and/or multifilaments, and a coating 27 of elastomeric material bonded to an outer surface 29, 29’ of the walls 12, 12’. The coating 27 has an indicia 28, including any desired symbol(s), number(s), letter(s), and the like, therein to provide a viewer viewing an outer surface 30 of the coating 27 with information, wherein the indicia 28 extends radially inwardly into the outer surface 30 of the coating 27 toward the central longitudinal axis 18 to provide the indicia 28 with depth (d) so as to avoid being easily worn away. Accordingly, the sleeves 10, 10’ can be shipped, stored and used without concern of the indicia 28 being worn away.
[0022] The indicia 28 does not extend through an entire thickness (t) of the coating 27 so as to avoid exposing the underlying outer surface 29, 29’ of the interlaced yam(s) 25. Accordingly, the depth d is less than the thickness t such that the yams 25 remain fully protected by the coating 27 over the entirety of the sleeve 10, 10’, including the region of the indicia 28, thereby avoiding exposure of the yam 25 to environmental elements (debris, thermal conditions. In accordance with one aspect, the depth d of the indicia 28 is between about 25-75 percent of the thickness t of the coating 27, and in accordance with a further aspect, to best ensure the indicia 28 is not worn away, the depth d of the indicia 28 is greater than 50 percent of the thickness t of the coating 27, but less than 75 percent of the thickness t to avoid unwanted exposure of the underlying yam(s) 25. [0023] The elastomeric material of the coating 27 can be provide as a silicone-based material, and the yam(s) 25 can be interlaced via being woven, braided or knited.
[0024] In accordance with another aspect of the disclosure, a method of constructing a textile protective sleeve 10, 10’ is provided. The method includes interlacing yam(s) 25 to form a wall 12, 12’ having an inner surface 21, 2 and an outer surface 29, 29’ extending between opposite ends 19, 20; 19’, 20’. Further, bonding a coating 27 of elastomeric material to the entirety of the outer surface 29, 29’ and forming an indicia 28 extending radially inwardly into an outer surface 30 of the coating 27 to provide the indicia 28 with a depth (d) so as to avoid being easily worn away.
[0025] The method can further include forming the indicia 28 so it does not extend through an entire thickness (t) of the coating 27, such that the depth d is less than the thickness t so as to avoid exposing the underlying outer surface 29, 29’ of the interlaced yam(s) 25.
[0026] The method can further include providing the elastomeric material of the coating 27 as silicone or a silicone-based material.
[0027] The method can further include interlacing the yam(s) 25 via one of a weaving, braiding or kniting process.
[0028] The method can further include forming the indicia 28 with a laser.
[0029] Depending on the application needs, the wall 12, 12’ can be constructed having any suitable size, including length and diameter. If the wall 12’ is formed as a self-wrapping wall, at least some of the weft-wise, circumferentially extending yam(s) 25, whether multifilament and/or monofilament, can be provided as any suitable heat-setable polymeric material, such as polyphenylene sulfide (PPS) or polyethyleneterephthalate (PET), for example. [0030] 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. In particular, all features of all claims and of all embodiments can be combined with each other, as long as they do not contradict each other.

1. A protective textile sleeve for providing protection to an elongate member contained therein, comprising:
a wall formed of at least one interlaced yam, said wall having an outer surface and an inner surface bounding a central cavity sized for receipt of the elongate member and extending along a central axis between opposite ends;
a coating of elastomeric material bonded to said outer surface of said wall, said coating having a thickness and an exposed outer surface; and
indicia extending radially inwardly into said exposed outer surface of said coating toward said longitudinal axis to provide said indicia with a depth.
2. The protective textile sleeve of claim 1, wherein said indicia does not extend through said thickness of said coating.
3. The protective textile sleeve of claim 1, wherein said depth of said indicia is less than said thickness of said coating.
4. The protective textile sleeve of claim 3, wherein said depth of said indicia is between about 25-75 percent of said thickness of said coating.
5. The protective textile sleeve of claim 3, wherein said depth of said indicia is greater than 50 percent of said thickness of said coating.
6. The protective textile sleeve of claim 1, wherein said elastomeric material is a silicone-based material.
7. The protective textile sleeve of claim 1, wherein said at least one yam is interlaced via being woven, braided or knitted.
8. The protective textile sleeve of claim 1, wherein said wall is a circumferentially continuous, seamless wall.
9. The protective textile sleeve of claim 1, wherein said wall has opposite inner and outer edges extending generally parallel to the central, longitudinal axis.
10. The protective textile sleeve of claim 9, wherein said opposite inner and outer edges are biased into overlapping relation with one another.
11. A method of constructing a textile protective sleeve, comprising:
interlacing yam to form a wall having an inner surface and an outer surface extending between opposite ends;
bonding a generally uniform thickness of a coating of elastomeric material to the outer surface; and
forming an indicia extending inwardly into an outer surface of the coating to provide the indicia with a depth.
12. The method of claim 11, further including forming the depth of the indicia to be less than the thickness of the coating.
13. The method of claim 12, further including forming the depth of the indicia to be between about 25-75 percent of the thickness of the coating.
14. The method of claim 11, further including providing the elastomeric material as a silicone-based material.
15. The method of claim 11, further including interlacing the yam via one of a weaving, braiding or knitting process.
16. The method of claim 11, further including forming the indicia with a laser.
17. The method of claim 11, further including forming the wall as a circumferentially continuous, seamless wall.
18. The method of claim 11, further including forming the wall having opposite inner and outer edges extending generally parallel to the central, longitudinal axis.
