F. P. Limited of Jersey, Channel Islands.

Method and device for the production of waterproof tape, cord or the like. Patented in the German Empire on July 1, 1923.

According to the Union Treaty of June 2, 1911, priority is due to this application of the applications in England of July 5 and October 7, 1922.

The invention relates to the manufacture of tape, yarn, ropes, and fabrics other material made from fibers, and it relates in particular to processes S which prepared spun or unspun fibers and silk, cotton and others Yarns are used for manufacture.

The purpose of the present invention is to use the previously known methods of the above kind to improve. There is a particular advantage of the invention in that with their help you can use fibers and the like, which you previously considered unsuitable held for this purpose, while at the same time taking advantage of the full strength of the Fibers and the like is secured. It also completely eliminates the adverse and perishable effects of moisture on the substances used, so that even those substances which are particularly exposed to these adverse effects are used beneficially can.

It has been proposed to use fibers or yarns with raw gum milk juice for the intended purpose to cover. This method has the disadvantage that raw gum milk juice has poor thermal properties; he namely becomes hard and inflexible in cold water and at relatively low levels Temperatures tough. Furthermore, the fibers are vulcanized after the impregnation of the tissue either destroyed or at least damaged. The damage to the fibers is due to the heat and pressure, which have to be expended in vulcanizing, inevitable.

In contrast, according to the invention, in the manufacture of tape, 4 " Yarn, cord, rope, fabric and other material fibers or yarns with vulcanized Gum milk juice coated or soaked. The objects produced by the new process are far from the others superior in terms of elasticity and breaking strength; the thermal properties are much better and the manufacturing costs of the finished items are lower.

The rubber milk juice is made using sulfur or another vulcanizing agent vulcanized under such conditions that coagulation of the rubber during the vulcanization is avoided, for the purpose of a solution or a colloidal suspension from vulcanized rubber in water. The vulcanization can be carried out, for example, as follows: 111 raw gummy milk juice that was 15 percent dry Gum and 1 g of sodium sulfide to 1600 g Containing dry rubber, 30 g of sulfur, 15 g of zinc oxide, 18 ecm of piperidine and 200 ecm of a casein solution mixed, which crystallized about 35 g of casein and S g Contains borax. The mixture is vulcanized by heating in a vulcanizing device, one for 30 minutes under a pressure of 3.5 atmospheres and then for 20 minutes at 3.5 atmospheres Pressure works. The vulcanized product consists practically of an aqueous one Solution or suspension of vulcanized rubber; it has very little or no coagulation during it the vulcanization took place.

Claims (1)

According to the invention one can also use in the production of tape, yarn, cord, Ropes, fabrics or other material made from unspun fibers, the latter with vulcanized Treat gum milk juice to bind them and hold them together so that they form a strip or band of certain Form latitude and of indefinite or definite length. ίο The strip can be spun or twisted to form yarn, string or the like, and such yarns or the like can also be twisted together or -spun: n to form stronger cords, ropes or the like. Furthermore, the strips can be used to cut a fabric of any length, Form width and strength; in general, the invention can be used in the manufacture of any Materials are used that was previously made of fibers or for the production made of fibers was suitable. Various suitable embodiments of devices for practicing the new method are shown in the accompanying drawings. In the construction of the devices, metals and similar suitable materials of this kind must be used and that no adverse chemical or other action during the \ ^r experiencing to prepare and impregnation with vulcanized rubber latex preserved in state may occur according to the invention. The containers, rollers, squeezing or scraping devices and, other machine parts that come into contact with; The prepared liquids or solutions, also with the rubber milk juice, are best made of hard wood, ebonite or other suitable material, stoneware, slate, glass or the like, which is not attacked by chemical or other harmful effects, so that harmful "After-effects" on the finished products are avoided.

The like. Hold for the finished product he j are required; i Fig. 3 shows a longitudinal section and a cross section through a suitable embodiment a comb roller with adjustable speed for removing the residues; Figs. 4 and 5 are schematic views of suitable embodiments of expressions or scrapers that can be used to clean up the superfluous gum milk juice to remove; FIG. 6 is a schematic side view of a modified embodiment of FIG Device, and the Figures 7 and 8 are front views of a portion of Figure 6 on a larger scale. In the device shown in Figs. 1 to 5, the material to be treated is removed from the usual spindle, bobbin or reel α and passed through a suitable voltage regulator b to a hot water bath c , through which it passes in the submerged state under suitable rollers d ' ; before it gets into the diluted alkali bath e , it goes through a squeezing device d which contains a roller corresponding to the material to be treated, by the action of which any excess water is removed before the material is added to the diluted alkali or to the bath c for prevention of curdling, in which it is either partially or completely submerged, as required, through the entire length of the container by going under or over rollers e , whereby a sufficient preparation for complete impregnation is achieved. The prepared material then goes to the rubber milk juice bath g, where it can be submerged or run over the milk juice roller f for the purpose of contact impregnation. The container for the vulcanized rubber milk juice is set up so that a minimum amount of milk juice is sufficient to carry out uninterrupted operation. A suitable device can also be arranged to bring about the continued necessary liquid movement when it is important to keep a mechanical mixture in a suitable desired state, which is necessary when the vulcanized gum milk juice with an addition of finish, drugs, filler 0. Like. Is used. The movement device w (Fig. 2) consists of a submerged flow line in connection with suitable deflection devices, which come into effect when a liquid flow is caused by the partially submerged impregnation roller f , and are arranged as shown. As the soaked material leaves the gum-milk bath it is picked up by a series of rollers, two of which, j and I, are shown; the material
