An air hose delivery assembly includes an external conduit. The air hose delivery assembly also includes a continuous inner liner disposed within the external conduit. The continuous inner liner is secured to the external conduit only at the ends of the continuous inner liner to form a tubular structure that is configured to be collapsed to a flat structure.

Protective covers for hoses, cables, ropes, and similar conduits formed of a composite fabric structure. The fabric structure has an inwardly facing layer in the form of a fabric base. The fabric base comprises a network of high tenacity fibers. The composite fabric structure also includes an outwardly facing layer formed of rubber. The inwardly facing layer and the outwardly facing layer are bonded together, preferably through the use of a bonding layer.

A flexible suction hose has supporting ribs that may be inflated to hold the hose open against suction for use and deflated to allow the suction hose to be folded or collapsed for storage and transportation.
摘要:
Method for protecting a cable or a pipe which includes the following stages: a geotextile strip is shaped like a sheath around the cable or pipe; and, the strip is fixed around the cable or pipe. The strip includes a single sheet of at least one layer of nonwoven material. The nonwoven material can be a multilayer material with a central layer of a nonwoven material with a low density and high mechanical strength and at least one outer layer covering it on at least one side, and advantageously on both sides, of higher-density nonwoven material. The geotextile can be heat-sealable and the fixing can in particular be carried out by heat-sealing 141.

A liquid-impervious tube, includes at least one first band helically wound on itself, characterized in that this first band is porous and pervious to gaseous fluids and in that it includes a second thin band which is pervious to gaseous fluids and impervious to liquids, and which is also helically wound on itself, with partial overlapping of its turns, said turns being secured to one another in a impervious manner so that the second band defines a liquid-impervious continuous covering.
摘要:
A tube with a tube wall composed of flexible material webs for covering pipe lines and for producing pipes and a unit for producing same. The tube wall is composed as a tube of two outer webs with longitudinal edges fused with one another and consisting of at least one tubular tension web made of glass fiber webs and mats lying in the interior of the outer covering. The longitudinal edges of the tension web are superimposed loosely to an overlapping, and the tension web is resin impregnated. The unit includes guide rollers, a core freely mounted on the guide rollers and made of core segments coupled with one another and having a width and an axis, clamping shafts projecting over the width of the core, reels mounted on the clamping shafts including material webs in a plurality of stations over and under the core, wherein the reels are offset with respect to the axis of the core and wherein the core extends through the plurality of stations and wherein the webs are guided around the guide rollers onto the core, and a cylinder downstream of the core being coupled to a front end of the core.
