This invention relates generally to protective textile sleeves for providing protection to elongate members contained therein, and more particularly to a tool for fixing a protective textile sleeve about an elongate member extending therethrough.
Protective textile sleeves for providing protection to elongate members extending therethrough are known. Typically, the protective sleeves are formed having one of a tubular wall having a circumferentially continuous wall, or a wrappable wall having opposite lengthwise extending edges configured to be wrapped into overlapping relation with one another. Depending on the type of aforementioned wall and end use, a portion of the sleeve can be fixed to itself to be maintained enclosed about the elongate member or to the elongate member extending therethrough via separately applied wrapped tape or glue applied during installation. The use of tape to secure the sleeve in place has various drawbacks, as it is costly from a material and labor standpoint, and it can also prove unsightly if not applied correctly. Further, the externally applied tape must be readily available during installation of the sleeve, otherwise the assembly process can be delayed, and further yet, the tape can become inadvertently damaged or ineffectively applied during assembly, such as by being inadvertently folded on itself or contaminated via dirty surroundings or hands during application, thereby adversely affecting the ability of the tape to reliably fix the sleeve about the elongate member as intended. The application of separately applied glue during assembly is also costly from a material and labor standpoint, and further requires being readily available during assembly of the sleeve, and can further add cost as a result of the need to provide drying time for the glue. In addition, glue lacks strength at elevated temperatures, and can prove messy in application, thereby leading to further cost associated with damage, repair and the necessary clean-up thereof. In addition to the aforementioned drawbacks, both known mechanisms discussed above can be time consuming in process, which ultimately adds cost to the process.

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:
Referring in more detail to the drawings,
Depending on the application needs, the wall 12, 12′ can be constructed having any suitable size, including length and diameter, wherein the inventive clamping tool 24 can automatically adjust to uniformly accommodate the dimensions and configuration of the sleeve 10, 10′. Further, the wall 12, 12′ can be formed of interlaced yarn using any desired interlacing process, such as braiding, weaving or knitting. If the wall 12 is formed as a self-wrapping wall, at least some of the weft-wise, circumferentially extending yarn, whether multifilament and/or monofilament, can be provided as any suitable heat-settable polymeric material, such as polyphenylene sulfide (PPS) or polyethyleneterephthalate (PET), for example. Further, if desired, at least some of the yarn can be provided as a low melt yarn, thereby being able to be melted during the fixation process to facilitate fixing the sleeve 10, 10′ to itself and/or to the elongate member 14.
If provided, the adhesive coating 22, 22′ can be applied as a low viscosity coating formulation or high viscosity coating formulation, such as via a spraying, rolling or dipping processes, by way of example and without limitation, directly on the desired area of the innermost and/or outermost surfaces 21, 21′, 23, 23′ of the sleeve 10, 10′. Of course, it should be recognized the coating 22, 22′ can be applied to the entirety of the wall 12, 12′, if desired. When relative movement between the sleeve 10, 10′ and the elongate member 14 is to be prevented, the mixture of the coating 22, 22′ is applied and bonded to at least a portion of the innermost surface 21, 21′ that abuts directly against the elongate member 14, thereby providing the ability to bond the adhesive coating 22, 22′ to an outer surface 25 of the elongate member 14 via activation by the clamping tool 24.
Upon applying, bonding, and drying the coating 22 to the desired areas of the wall 12, the wall 12 can be subsequently heat-set into a self-wrapping wall and/or wrapped about the elongate member 14. Otherwise, it should be recognized that the wall 12 can first be heat-set into a self-wrapping wall and then the wall 12 can be sprayed, dipped or otherwise coated with mixture of coating 22 in the desired areas.
It should be recognized that upon the coating 22, 22′ being applied to the wall 12, 12′, the coating 22, 22′ attains its first, non-adhesive state upon being dried, and then, when desired, including after storing in inventory and/or shipping to the desired location where the sleeve 10, 10′ is to be disposed about the elongate member 14, the coating 22, 22′ can be selectively activated in accordance with the disclosure to form a bond with the desire surface via the clamping tool 24.
Upon the sleeve 10, 10′, being clamped, heated, and cooled in a continuous process sequence, as discussed further below, the adhesive coating 22 becomes activated and at least partially melted and solidified, thereby causing the adhesive 22 to form a bond joint with the adjacent abutting surface, whether another portion of the sleeve wall 12, 12′ and/or the outer surface 25 of the elongate member 14. The entire coating activation process can take as few as about 6-10 seconds, by way of example and without limitation.
The clamping tool 24 includes at least one clamp assembly 26, and in
The opposed heating and cooling clamp members 28, 30 of each of the clamp assemblies 26 can be supported by a housing 44. The housing 44 can be formed being generally U-shaped having a base 46 and a pair of upstanding support columns 48 spaced from one another by a slide channel 50 sized for clearance receipt of the textile sleeve 10, 10′ therein for free clearance movement of the textile sleeve 10, 10′ between the heating and cooling clamp members 28, 30. The plurality of clamp assemblies 26 are spaced in mirrored, axially aligned relation with one another (axially aligned along an axis extending generally transversely to the first, second axes A1, A2 and generally parallel to the central axis 18 of the sleeve 10, 10′) such that the channels 50 are axially aligned with one another for simultaneous receipt of the textile sleeve 10, 10′ therein. Each of the opposed heating clamp members 28 can be supported on a separate one of the support columns 48 for movement toward one another along the first axis A1 to the closed state and away from one another along the first axis A1 to the open state. Likewise, each of the opposed cooling clamp members 30 can be supported on a separate one of the support columns 48 for movement toward one another along the second axis A2 to the closed state and away from one another along the second axis A2 to the open state. The heating clamp members 28 are shown below the cooling clamp members 30, by way of example and without limitation. The carrier 40 of each clamp assembly 26 is configured for sliding movement along the columns 48 of the housing 44 to carry the textile sleeve 10, 10′ along the third axis A3 from the open, loading/unloading position to a heating location aligned between the heating clamp members 28 and then to a cooling location aligned between the cooling clamp members 30 and then back along the third axis A3 to the open, loading/unloading position.
