Definitions

• This invention relates to a fabric enclosed cable and the method of assembling a cable with a fabric sleeve so that the cable may be easily inserted into a communications conduit.
• a method of attaching a fabric material to a cable includes the steps of positioning an adhesive on opposed layers of fabric, positioning a cable between the layers, and attaching the adhesive of one layer to the adhesive of the other layer to confine the cable between the layers.
• the wrapped cable formed by this method includes a fabric encased cable having at least one wing extending outwardly from the cable.
• Fig. 1 is a sectional view of a cable positioned between two layers of fabric material.
• Fig. 2 is a sectional view like Fig. 1 but showing the layers wrapped around the cable.
• Fig. 3 is a fragmented top plan view of that which is depicted in Fig. 2.
• Fig. 4 is a sectional view of an alternative embodiment to that shown in Fig. 1 , and showing a cable positioned between two layers of fabric material.
• Fig. 5 is a sectional view like Fig. 4 but showing the layers wrapped around the cable.
• Fig. 6 is a sectional view of yet another embodiment depicting two opposed layers of material.
• Fig. 7 is a sectional view showing that which is shown in Fig. 6 wrapped around a cable.
• Fig. 8 is a fragmented top plan view of that which is depicted in Fig. 7.
• a conventional communications cable is indicated by the numeral 10 in the drawings.
• Cable 10 traditionally includes core of wires covered by a plastic sheath. Such cables are usually stored on a roll, which may carry 2500 feet or more of cable.
• a first sheet assembly in order to wrap a cable 10 with a pliant material, such as a fabric with a lower coefficient of friction than the sheath of the cable, a first sheet assembly, generally indicated by the numeral 11 , and a second sheet assembly, generally indicated by the numeral 12, are provided.
• Sheet assembly 11 extends longitudinally along the length of cable 10 and includes a fabric layer 13 having an adhesive layer 14 attached thereto.
• sheet assembly 12 extends longitudinally along the length of cable 10 and includes a fabric layer 15 having an adhesive layer 16 attached thereto.
• assemblies 11 and 12 are positioned as shown in Fig.
• assemblies 11 and 12 are wrapped around cable 10 with adhesive layers 14 and 16 engaging cable 10 to form wrapped cable 17.
• the lateral edges of assemblies 11 and 12 form wings 18 when the lateral edges of adhesive layers 14 and 16 engage each other.
• the wings 18 extend radially outwardly from generally diametrically opposed sides of cable 17. Such wings 18 tend to add strength to the cable 17, and they can be utilized to pull the cable into a conduit. That is, a pulling device can be attached to, or otherwise grasp, the wings of a cable to insert it into a conduit.
• the wrapped cable 17 can be created by longitudinally moving cable 10 together with sheet assemblies 11 and 12 and providing a folding station. When the cable 10 and assemblies 11 and 12 pass through that station, assemblies 11 and 12 are wrapped around cable 10 as previously described. Such can be accomplished at the manufacturing site of the cable, or such can be provided at the site where the wrapped cable 17 is to be installed in a conduit. In that instance, a roll of cable 10 and rolls of sheet assemblies 11 and 12 can be provided and fed through a device which will wrap cable 10 as the resultant cable 17 is being installed in a conduit.
• Sheet assembly 11 includes a fabric layer 23, which can be identical to fabric layer 13.
• Sheet assembly 23 also includes an adhesive layer which is formed of two small layers 24 located at the lateral peripheries of fabric layer 23.
• sheet assembly 22 includes a fabric layer 25 which can be identical to fabric layer 15.
• Sheet assembly 22 also includes an adhesive layer which is formed of two small layers 26 located at the lateral periphery of fabric layer 25.
• assemblies 21 and 22 are positioned as shown in Fig. 4, the adhesive layers 24 and
• Fig. 5 being opposed to each other with cable 10 being positioned between sheet assemblies 21 and 22. Then assemblies 21 and 22 are wrapped tightly around cable 10 and adhesive layers portions 24 engage adhesive layer portions 26, as shown in Fig. 5 to form wings 28. It is also contemplated that the embodiment of Fig. 5 will satisfactorily create a cable 17 if only one of the sheet assembles 23, 25 is provided with an adhesive portion 24 or 26. Thus, the remaining adhesive portion would be attached directly to the opposed sheet assembly. In either event, the resulting plan view of Fig. 5 is identical to Fig. 3. The resulting fabric wrapped cable 17 can be manufactured in the same manner as described with respect to the embodiment of Figs. 1 -3.
• FIG. 6-8 Another cable wrapping version is shown in Figs. 6-8.
• one continuous sheet of fabric material generally indicated by the numeral 30, is folded to form a first fabric layer 33 having a small adhesive layer 34 at the end thereof, and forms a second fabric layer 35 having a small adhesive layer 36 at the end thereof.
• a release sheet 37 is positioned on each adhesive layer 34, 36.
• a cable 10 is positioned between layers 33 and 35 by extending it through the opening between adhesive layers 34 and 36. Then the release sheets 37 are removed from adhesive layers 34, 36, and layers 33 and 35 are tightened around cable 10 to form a wrapped cable 17 with the adhesive layers 34, 36 being attached to each other to form a wing 38.
