Abstract

The utility model relates to a reed used during a curtain cloth manufacturing process. The reed comprises a top beam, a bottom beam and a plurality of reed wires, wherein the upper and lower ends of the reed wires are respectively connected between the top beam and the bottom beam; the thickness of four reed wires on edge parts on two sides of the reed is designed as being gradually changed, i.e., the thickness from inner side to the edge parts is gradually increased; the clearances between four reed wires are gradually narrowed from the inner side to the edge parts; except for the four reed wires on the edge parts on two sides of the reed, the other reed wires are designed in sections; the clearances between the reed wires in each reed wire section are same in density; the density of the reed wires in the reed wire section in the middle of the reed is maximum; the density of the reed wires in the reed wire sections on two sides of the reed is gradually reduced; a single warp is inserted into the clearances of the four reed wires on the edge parts on two sides of the reed; and two warps are inserted into the clearances of the other reed wires, except for the four reed wires on the edge parts on two sides of the reed. The reed used during the curtain cloth manufacturing process has the advantages that the weaved curtain cloth is uniform in warp distribution, the breaking frequency of joints during the process of replacing bobbins for weaving the cloth is reduced, and the production efficiency is increased.

Description

The reed that uses in the cord fabric manufacture process

Technical field

The utility model relates to a kind of fabric knitting device, specifically is the reed that uses in a kind of cord fabric manufacture process.

Background technology

In the Cord Fabric Production process; The stage of weaving cotton cloth is all controlled the distribution of warp through reed, the close reed of singly going into such as generally adopt now, sees also shown in Figure 1; Steel button 1 comprise back timber 12, bottom girder 14 and up and down two ends be connected a plurality of reed wires 16 between back timber 12 and the bottom girder 14 respectively; All reed wires 16 equidistantly separate, and just the reed wire of existing reed is evenly distributed, and only wear a warp in the gap of reed wire.But not enough below in use existing:

1) etc. close reed reed wire evenly distributes, and being in that warp in the reed wire gap distributes this moment also should be uniformly, but in the actual production process of weaving cotton cloth; Because of weft yarn has certain shrink; The fabric width of the cloth that is made into is less than the fabric width of reed, and the contraction at the edge of cloth causes the inhomogeneous of cloth cover warp distribution greater than the contraction of centre; The warp density at limit portion 0～40cm place is greater than the centre; High 1～4/10cm does not wait, and cord fabric is the framework material of tire, and the inhomogeneities that warp distributes will influence the stressed irregular of each position in the tire;

When 2) weaving cotton cloth for guaranteeing high efficiency, when last batch line tube casted off, the end of a thread that need will following batch of line tube and last batch join, like this through the traction of last batch line, let down and criticize the line bucket and cross reed.If adopt and singly to go into reed, just a warp is only worn in the space between reed wire, the warp radical of cord fabric for a long time, the gap between reed wire is little, and the tyre cord warp is thick, easy fracture when causing joint to cross reed need be done over again again, influences efficient.

The utility model content

The technical problem that the utility model will solve provides the reed that uses in a kind of cord fabric manufacture process that the cord fabric warp weaved out is evenly distributed.

The utility model adopts following technical scheme to solve the problems of the technologies described above: the reed that uses in a kind of cord fabric manufacture process; Comprise back timber, bottom girder and up and down two ends be connected a plurality of reed wires between back timber and the bottom girder respectively; The thickness of four reed wires of reed both sides of the edge portion carries out the gradual change design, promptly thickeies gradually from the thickness of interior side direction edge part.

This utility model can further be specially:

Four reed wires except reed both sides of the edge portion; Other reed wires adopt segment design; Promptly be divided into a plurality of reed wire sections; The density in the gap between the reed wire in each reed wire section is identical, is positioned at the density maximum of the reed wire of the middle reed wire section of reed, and the density of the reed wire in the reed wire section of reed both sides is rare gradually.

Whole reed is divided into 5～13 sections usually.

Penetrate single warp in the gap of four reed wires of reed both sides of the edge portion,, penetrate 2 warps in all the other reed wire gaps except four reed wires of reed both sides of the edge portion.

Gap between four reed wires narrows down from interior side direction edge part gradually.

The advantage of the utility model is: the cord fabric warp of weaving out is evenly distributed, and can reduce the fracture frequency of joint when weaving cotton cloth the thread-changing tube simultaneously, has improved production efficiency.

Description of drawings

Fig. 2 is the structural representation of the reed that uses in the utility model cord fabric manufacture process.

The specific embodiment

See also shown in Figure 2, the reed 10 that uses in the utility model cord fabric manufacture process comprise back timber 102, bottom girder 104 and up and down two ends be connected a plurality of reed wires 106 between back timber 102 and the bottom girder 104 respectively.

The thickness of four reed wires 106 of reed 10 both sides of the edge portions carries out the gradual change design; Promptly thicken gradually from the thickness of interior side direction edge part, and four reed wires 106 between the gap narrow down gradually from interior side direction edge part, and in weaving process; Penetrate single warp in the gap between these four reed wires 106; This kind structure Design is because increased the spacing between the edge part warp, and therefore having improved several warps in cloth edge more is prone to intensive phenomenon, simultaneously because reduced the gap between the reed wire 106; Therefore the space of walking about that has reduced limit portion warp, the stability of raising selvedge.

Except four reed wires 106 of reed 10 both sides of the edge portions, other reed wires 106 adopt segment design, promptly are divided into a plurality of reed wire sections; The density in the gap between the reed wire in each reed wire section is identical; But the density of the reed wire in the different reed wire sections is different, and promptly the density of reed wire adopts gradual change type to distribute, and is positioned at the density maximum of the reed wire of the reed wire section in the middle of the reed 10; The density of the reed wire in the reed wire section of reed 10 both sides is rare gradually; Therefore compensated the big influence of cord limit portion contraction when weaving cotton cloth, it is fixed that segments can come through close uniformity requirement according to product, usually reed is divided into 5～13 sections and just can satisfies all demands basically.

In weaving process; Except four reed wires 106 of reed 10 both sides of the edge portions, the warp list in all the other reed wire gaps gone into to change into warp is two goes into, penetrate 2 warps in the gap of promptly every adjacent two reed wires; Reduced the reed wire sum like this; The gap that makes reed wire is brought up to more than the 1.5mm by 0.7 original～1.0mm, is convenient to joint and passes through.

Experiment showed, and use the reed that uses in this new cord fabric manufacture process, when 7 sections designs, weave the cord fabric that comes through close (error of root/10cm) can reach ± 1, can connect the fracture frequency that reduces joint when weaving cotton cloth the thread-changing tube simultaneously, lower more than 30%.
