Detailed description of the Invention
With reference now to Fig. 1,, assembly drum designed 10 are used to construct tire, wherein with technology known in the present technique at least one deck rubber layer and selectively miscellaneous part be layed in assembly drum designed on.The composite casing casing ply is applied to assembly drum designed on during the traditional tire of structure, the soft cover 14 of polymer filament (net material) of interlocking is moved on this rubber components assembly drum designed and that before added from a side of drum 10, according to used here, the nothing of " soft cover " vial shape splicing fabric web, it comprise name radially with the cord or the silk of nominal broadwise.So-called " name footpath silk " is meant that with " nominal tram " this class silk is to be under the relative mutually angle, and why be because described silk is not footpath silk and the tram under the ordinary meaning with this title, because such name footpath silk will have identical physical characteristic with nominal tram under most of situations, under many situations, these generals neither cut-off line direction also are orientated not according to the machine direction of fabric simultaneously.
Shown in form of implementation, name footpath silk 16 and nominal tram 18 in soft cover 14 in its intersection point 19 places consolidation.Silk 16 and 18 can the thermoplastic polymer be expected preparation.The thermoplastic that is fit to can be selected from nylon, polyalkylene amide and polyester and their mixture.
For the silk screen of this consolidation is distinguished mutually with following woven or knitted structure, this polymeric web is called " network mesh " sometimes at this.
Network mesh is radially to make with the fusion silk of nominal broadwise by the name of pushing thermoplastic simultaneously, wherein the fusion materials flow of subtend intersect and its temperature drop to its fusing point when following consolidation to together.Can be by the net that this process is made available from Applied Extrusion Technologies, 96 Swampscott Road, Salem, MA; Conweb Plastics, 2640, Patton Rd, Rockville, Md.55113; NSW Corporation, the tame branch company of Siemans, 530Gregcry Ave, Roanoke, Va.24016, and various other suppliers.
The footpath yarn count of above-mentioned network mesh material, per inch footpath yarn number (epi) and each diameter and cross section shape can be by number, shape, spacing and the size Control of extrusion mouth mould mesopore.
In other forms of implementation, the net material of interlocking can be knitting or woven, adopts any twisting or the fabric of not twisting or wire cord or cable.The net of interlocking can be made for and make its footpath silk and tram relation object be similar to above-mentioned molten polymer, just the not consolidation of intersection point of footpath silk and tram and can move relative to each other at limit internal diameter silk and the tram that the structure that net is expected is stipulated.
The soft cover that is used for the net material of tire reinforcement plies is made for the soft cover of deformable that makes its cut-off footpath can allow this reinforcing mat material and is easy to move to assembly drum designed, but can be not loose cause fold when elaborating on this reinforcement material on bulging when tyre bead and miscellaneous part.In some cases, the soft cover of net material can " stretchings " as described below, makes its diameter less than assembly drum designed, but because its deformability and its intrinsic extensibility, this net material can be stretched be easy to be coupled to assembly drum designed on.
In United States Patent (USP) 5513683 and the technical description wherein quoted as proof, the stretching of silk material has material impact to its physical property as people such as Causa.Because the character of described web frame, " stretching " comprise that " master " of web frame stretches and " pair " of silk material stretches.
It is the diameter that it will be used for tire wherein at least that the soft cover of described net material can be designed to make its diameter to be stretched to, and can be stretched to diameter greater than this diameter of tyres, in it is used, to stand providing balance between required flexible of normal deformation at the required restriction character of casing ply and tire.
Below referring to Fig. 2, at net reinforcement 14 after in place on assembly drum designed 10, can be to this net material, and then move tyre bead 22 in place with another rubber layer 21 laies.
With reference to figure 2a, the selective triangular rubber core that employing may be added, wedge and other this structures to the peculiar parts of special tire construction, or the first order carcass 15 among the figure can place memory point from assembly drum designed taking off, maybe can continue assembling and a tire construction is provided, at this moment be to place the first order carcass mould to launch, with contact with adhere to band bundle and the tyre surface that assembles in advance, make them one arise from the mould and vulcanize then.
Referring to Fig. 2 b, in another kind of tire construction, do not need band bundle, tyre surface 29 can be attached on this first order carcass before assembly drum designed taking off at first order carcass, first order carcass/tyre surface 15a is launched in tire-mold and vulcanizes.
Expert scholar knows that in addition additive method is used for tire assembly with first order carcass, and the step of separating that for example can be before placing pre-assembled green tire in the sulfurizing mould is launched carcass and be adhered on the pre-assembled band bundle.Using the pre-assembled additive method of the present invention in the structure tire is that expert personage is known.
In the another kind of method of fit a tyre, referring to Fig. 3, can start assembly drum designed 10 shapes, promptly shorten assembly drum designed and make tyre bead more together approaching, go the turnup tyre element part between two tyre beads 26 (referring to Fig. 2) not vertically with turn-up bladders 27 then tyre assembly generate tire.When the tire drum starts in this deployment step and when making tyre element get the shape of tire, net material reinforcement plies 14 will be tightened and the silk of netting material will be fit to the tire shape convergent-divergent.Silk is cross-coupled owing to can make this silk possess very big intensity, and tire just can not add the band reinforcement in addition and be configured to.
In addition, know, depend on the requirement of strength of specific tires, can adopt the soft cover net of multilayer material as expert scholar.
Referring to Fig. 3 a and 3b, after deployment step, tyre sidewall 24 and band can be added on the tire of expansion.In Fig. 3 a, show the band 62a of bright routine and setting up of 64a.In Fig. 3 b, be to be similar to the soft cover of carcass but width with band cuts off by the size of pipe by the made another kind of other net material with 62 and 64 advantage, so make it need not simultaneously splicing.
