Definitions

  • the present invention provides a method and means for the manufacture of fluid-tight hoses, especially fire hoses.
  • the hoses used for fire-fighting for example are generally manufactured from a woven textile sheath which provides the mechanical strength of the hose. Fluid-tightness may be afforded in various ways, especially by the introduction and adhesion inside the textile sheath either of a non-porous tube consisting of a textile liner impregnated with latex or plastic material, or of a tube of rubber or plastic material, or again by lining the textile sheath with latex or plastic material.
  • Articles made from woven material are twisted or stretched more or less according to the methods of manufacture used.
  • the internal liner may become detached under high pressure.
  • the textile sheath must be handled with care, for if a warp thread is damaged, there is danger of the sheath bursting.
  • the present invention has for its main object to provide an improved hose in which these disadvantages are avoided, the improved hose not consisting of a woven textile sheath, but being made in a continuous length by means of threads or wires intimately interconnected by natural or synthetic rubber or by plastic material.
  • the hose is made up of threads disposed in the direction of the length of the hose to be manufactured, forming as it were the generatrices of a cylinder, and of other threads disposed transversely to form spirals around the longitudinal threads, all the threads being connected together by rubber or plastic material.
  • the threads disposed in the direction of the length of the hose will be called the warp threads, by analogy with the art of weaving, and the threads disposed in the direction perpendicular thereto will be called the weft threads, although there is essentially no weaving action and interwoven threads are not employed.
  • the cylinder e is of tension of the weft threads k.
  • the warp threads a are drawn parallel with the generatrices of the cylinder, and cover its entire surface; they pass upwardly through the middle of a tank 1 containing an adhesive, for example an emulsion of synthetic rubber. On issuing from the liquid in the tank, the threads pass through a scraper f, which regulates the thickness of the adhesive layer deposited on the threads.
  • the bundle of coated threads next travels upwards into a heating zone g, constituted, in the example represented by an enclosure heated by internal electric resistances g From this heating zone, the bundle of threads passes into a drying or cooling zone g constituted in the example represented by another enclosure adjacent to the first, and into which cold air is introduced by way of a duct g
  • the coating operation followed by heating and air-cooling can be repeated a number of times along the cylinder e, in order to obtain a coherent and fluid-tight film of any desired thickness, forming a continuous tube, as indicated at h.
  • the tube It thus formed which is to constitute the in ternal fluid-tight wall of the hose, arrives at the top of the cylinder e, the upper edge e of which is thickened and rounded.
  • the tube is turned inside out by folding back over this edge and it returns down the interior of the cylinder, wherein it fits over a mandrel i coaxial with the cylinder e.
  • This mandrel is held at the top by a rod i fixed to the frame n of the device.
  • talc or other lubricant is introduced through the open top of the cylinder e.
  • a plate 1' Around the mandrel i and concentric therewith there is rotatably mounted a plate 1', suitably set in rotation, for example as represented by means of a gear wheel 1' meshing with a bevel pinion i carried by the shaft of a motor i
  • the plate 1' carries a plurality of spools on which the weft threads k are wound.
  • This plate acting like a shuttle, deposits the weft threads around the tube h as it rotates about the latter, these threads being laid in the manner of a binding.
  • the ratio between the speed of rotation of the plate and the speed of linear movement of the tube h determines the weft density, as it may be called, by its resemblance to a weaving operation.
  • the weft threads are guided by a system of rollers k k k so as to pass down into a tank 1' containing for example an emulsion of synthetic rubber, with which they become coated.
  • the rollers k over which the threads pass may be braked or otherwise controlled so as to exert a higher or lower traction upon the threads, this control being dependent upon the rotation of the plate 1'.
  • the tube bearing the weft threads wound upon its exterior, then passes into a heating zone I, maintained at a desired heat by electric resistances l and into a drying or cooling zone 1 to which cold air is supplied through one duct and from which the air is discharged through another duct l
  • the following operation consists in passing a fresh layer of warp threads m (similar to the warp threads a) into a bath m wherein they are coated with latex emulsion for example and in bringing these coated Warp threads m by means of a ring it against the exterior of the tube h under manufacture.
  • the whole then passes into a heating zone q provided with electrical resistances V q and into a drying or cooling Zone q supplied with cold air which is discharged through a duct q
  • the second shuttle plate 0 may be rotated in a direction opposite to that of the first shuttle plate j; for example, as represented, in the case of the plate 0, the engagement of the gearing 0 and the pinion 0 carried by the shaft 0 of the motor 0 may be reversed.
  • the above operation may be repeated several times.
  • the finished hose will be passed between draft rollers r situated at the end s of the mandrel i, this end being shaped, as shown in the drawing, to facilitate the sliding of the finished hose.
  • the draft rollers r may be replaced by other means such as slideways or the like, provided with grippers between which the hose is engaged and drawn along.
  • metal wires for example made of stainless steel, or synthetic threads having high resistance to tension.
  • Any torsion which the hose tends to assume can be reduced or practically annulled by the use of threads having torsions in different directions.
  • the hose may consist of a plurality of layers of warp and weft threads, its resistance to abrasion is considerably increased. Should an outer thread be accidentally cut, the remaining strength of the hose will still be acceptable.
  • the uniform distribution of the warp and weft threads increases the strength and permits of reducing the Weight of material used, for the same result.
  • the invention facilitates'the manufacture of almost all kinds of hoses, Whether flexible, semi-rigid or rigid, at relatively low cost.
  • the apparatus is arranged with its axis vertical. It will be understood that the manufacture can also be carried out on a horizontal axis according to the same method.
  • a method of making a tubular hose comprising the steps of laying a plurality of parallel threads as generatrices of a cylinder With said threads lying parallel to the axis of said cylinder, coating said threads with an adhesive medium, heating said coated threads for solidifying said adhesive medium, turning said coated threads inside out after solidification of said adhesive medium so that said coated threads form the interior of said hose, winding a plurality of threads spirally around the exterior of said parallel threads when turned inside out, coating said spirally Wound threads with an adhesive medium, and heating said spirally wound and coated threads for solidifying said last named adhesive medium thereon.
  • a method of making a tubular hose comprising the steps of laying a plurality of parallel threads as generatrices of a cylinder with said threads lying parallel to the axis of said cylinder, coating said threads with an adhesive medium, heating said coated threads for solidifying said adhesive medium, turning said coated threads inside out after solidification of said adhesive medium so that said coated threads form the interior of said hose, winding a plurality of threads spirally.
