Abstract: An elongated sleeve structure for insertion and protection of elongated items within a duct is disclosed. The sleeve structure is formed from a flexible sleeve woven from warp and fill yarns to produce opposed layers in closely spaced relation. The layers have a common seamless edge and are joined along a second edge by a knit stitch formed by interlooping of successive traverses of the fill yarn which is common to both layers. The layers are of equal width and are resiliently separable into a spaced apart relationship defining a central space which accommodates the elongated items. A pull tape is positioned between the opposed layers for drawing the elongated items through the sleeve central space once the sleeve structure is positioned within the duct. Multiple sleeve structures may be joined together in an assembly using an attachment piece allowing a plurality of sleeve structures to be pulled simultaneously.

Abstract: A sleeve assembly for receiving and protecting elongated items within a duct is disclosed. The sleeve assembly includes a plurality of separate and independent sleeves, each sleeve being woven from warp and weft filamentary members that form sidewalls surrounding and defining a central space. Pull cords are located within each central space for drawing the elongated items through the sleeves once positioned within a duct. The assembly includes means for drawing the sleeves simultaneously through the duct, such means including an outer jacket surrounding the sleeves, the jacket having an inwardly facing surface that exerts a compressive force on the sleeves causing them to be drawn through the duct together with the jacket. The means may also include a loop which attaches the sleeved together at one end. The sleeves may be biased into an open or a substantially flattened configuration.
