Abstract: An annulated tubular sheath which is split down a longitudinal section thereof. According to the invention, a longitudinal strip of the sleeve is made of a flexible material and is disposed in an angular position of 5-180 degrees in relation to the longitudinal section or is disposed in the region of the sheath in which the longitudinal section is made. Preferably, the flexible material is a thermoplastic elastomer. The invention also relates to a method for producing a sleeve by extruding a plastic material, a longitudinal strip made of a flexible material obtained by co-extruding an elastomer material. A device for carrying out said method comprises an extrusion head provided with an insert for placing the co-extrusion in a stop position on a die in order to block the flow of the extruded plastic material and to enable the flow of elastomer material.

Abstract: Sleeving to protect an object, extending in a longitudinal direction and comprising filaments braided together and filaments interlaced with the braided filaments in the longitudinal direction of the sleeving, the braided filaments consisting of thermoplastic polymer monofilaments and the interlaced filaments consisting of multifilaments, the sleeving being slit in a longitudinal direction to be opened when the object to be protected is inserted, and closing around this object through elastic recall exerted by the thermoplastic monofilaments. According to the invention, the protective sleeving includes a polymer coating adhering to the braided and interlaced filaments on the side destined to surround the object to be protected. The coating is preferably of silicon or acrylic polymer.
