Abstract

The utility model relates to a warp separating reed for tyre fabrics weaving. The technique scheme of the warp separating reed for tyre fabrics weaving is: an irregular reed for tyre fabrics weaving comprises dents and is characterized in that the dents are divided into an intermediate zone and a plurality of zones in symmetrical arrangement along the intermediate zone from the center to both sides, the width of the plurality of zones is on the decline from the center to the both sides, and the density of the dents is on the decline from the center to the both sides. The useful effects of the irregular reed for tyre fabrics weaving is that in the process of manufacturing the tyre fabrics, due to the fact that the density of reed dents are designed and adjusted, the middle and bilateral warps of end tyre fabrics are prone to be even, and even the density is basically equal, so that tyres with excellent dynamic balance is obtained in the subsequent procedures.

Description

A kind of for the woven irregular reed of cord fabric

Technical field

The utility model relates to a kind of cord fabric lease making reed of weaving.

Technical background

After cord fabric used common reed to weave cotton cloth to finish, the right and left and middle warp density equated, and after through impregnation heat treatment tension force stretching, fabric width shrinks, and causes the both sides warp density larger than middle warp density, thereby affects the dynamic balancing of subsequent tyre.

Summary of the invention

The purpose of this utility model is to overcome the defects that prior art exists, a kind of irregular reed is provided, its conversion reed dent density, so that the warp density trend of the cord fabric of impregnation heat treatment after finishing evenly, preferably can reach density substantially equal, thereby guarantee in down-stream, to obtain the tire of excellent dynamic balancing effect.

The technical solution of the utility model is: a kind of for the woven irregular reed of cord fabric, comprise dent, it is characterized in that, described dent be divided into the mesozone and with respect to described mesozone symmetrical from the centre to a plurality of districts on both sides, the width in described a plurality of districts reduces gradually from the centre to both sides, and a plurality of districts of dent density from the mesozone to both sides reduce gradually.

One preferred embodiment in, described a plurality of districts are at least 4 on every limit, and described dent density the adjacent region variability with 2-5% changes from the mesozone to a plurality of districts on both sides.

More preferably, described a plurality of districts are at least 6 on every limit, and the adjacent region variability with 2-4% changes described dent density from the mesozone to a plurality of districts on both sides.

The beneficial effects of the utility model are: when being used for the cord fabric manufacturing, because reed dent density has been carried out design modifying, so that the cord fabric after machining is middle and warp density trend in both sides is even, even density is basically equal, thereby obtains the tire of excellent dynamic balancing effect in down-stream.

The specific embodiment

Now by reference to the accompanying drawings the utility model is specifically described.

Fig. 1 shows existing a kind of for the woven close reed constructions schematic diagram such as common of cord fabric.Shown in Fig. 1, reed 100 is at its Zone Full, and such as

other district

11 and 12 outside mesozone 10 and the mesozone, dent density is constant.Because close reed 100 each dent spacing such as this equate,

other district

11,12 of the cloth of weaving out is identical with the mesozone warp density.But this cloth through impregnation heat treatment after,

other district

11,12 is different with mesozone 10 warp density, the zone on generally both sides can than the centre 2-4 of manying root/inch (1 inch=25.4mm).This just causes follow-up when carrying out tyre production, and lay particular stress on tire part position, affects the dynamic balancing effect.By analysis, the generation of this situation may be owing to being subject to large warp-wise tension force stretching, the fabric width direction produces shrinks, and the shrinkage factor of both sides and centre is not identical when shrinking, middle shrinkage factor is little, the both sides shrinkage factor is large, therefore just cause cord fabric after impregnation heat treatment is finished in the mesozone 10 and other to distinguish 11,12 warp density different.

For solving the problems of the technologies described above, the inventor designed a kind of as shown in Figure 2 be used for the woven irregular reed of cord fabric.The dent density of this irregular reed is inhomogeneous.Specifically, irregular reed 200 comprises outside mesozone 20 and the mesozone a plurality of districts symmetrical with respect to mesozone 20.Fig. 2 has specifically illustrated the left side that 4 district 211,212,213, the 214(s symmetrical with respect to mesozone 20 are positioned at mesozone 20) and 221,222,223,224(is positioned at the right of mesozone 20).The width in described a plurality of districts reduces to both sides gradually from the centre, and the district 211 on the preferably limit, 221 width are all 1/8 to 1/6 of mesozone 20 width.

Dent density in described a plurality of district 211,212,213,214,221,222,223,224 reduces to both sides gradually with respect to the dent density of mesozone 20.I.e. 20 the left side in the mesozone, the dent density in district 211 less than the dent density in the dent density in district 212, district 212 less than the dent density in the dent density in district 213, the district 213 dent density less than district 214.The right of 20 in the mesozone, district's dent density of 221 less than the dent density in the dent density in district 222, district 222 less than the dent density in the dent density in district 223, the district 223 dent density less than district 224.Dent density from the mesozone the preferred ramp in a plurality of districts to both sides dwindle, such as 20 the left side in the mesozone, the dent density in district 214 reduces approximately 2-5% with respect to the dent density in district 20, distinguish 213 dent density and reduce approximately 2-5% with respect to the dent density of distinguishing 214, distinguish 212 dent density and reduce approximately 2-5% with respect to the dent density of distinguishing 213, distinguish 211 dent density and reduce approximately 2-5% with respect to the dent density of distinguishing 212.Also be like this on the right.Yet, the application be not limited to dent density from the mesozone a plurality of districts ramp to both sides dwindle, also can adopt not ramp, but the variability of adjacent two district's dent density is controlled between the 2-5% also.

Adopt irregular reed among Fig. 2 can weave the warp density cord fabric that to the left and right sides district reduces gradually from the mesozone.The cord fabric of this different warp density can obtain in each district relatively uniformly warp density after the heat treatment of process impregnation.The tire that adopts this cord fabric to produce has better dynamic balancing effect compared to existing technology.

In order further to obtain through impregnation heat treatment by the more uniform cord fabric of line density, also can be with described a plurality of districts Further Division, thus obtain more to distinguish.For example, as shown in Figure 3, leftmost two districts can be further divided into respectively two

districts

3111,3112 and 3121,3122, rightmost two districts are further divided into respectively two

districts

3211,3212 and 3221,3222.Like this, just there are respectively 6 districts on 30 both sides to irregular reed 300 in the mesozone, and the dent density in the district that newly is divided into from the mesozone 6 preferred ramps in district to both sides dwindle, and variability can be controlled between the 2-4%.Similarly, also can adopt not ramp, but the variability in adjacent two districts also should be controlled at 2-4%, in the scope of preferred 2-3%.District 3111 among Fig. 3 on the limit, 3211 width are all 1/16 to 1/12 of mesozone 30 width.

Based on the description to the utility model preferred embodiment, should be clear, the utility model that is limited by appending claims is not limited only to the specific detail set forth in the top specification, and what do not break away from the utility model aim or scope may reach the purpose of this utility model equally to many apparent changes of the present utility model.
