Blowout is presented to increase, but ultrathin fabric, because its difficulty of weaving is big, yields is low, technical threshold is high, and the country still cannot provide, and supply
Should be concentrated mainly on that Japanese NTB, UNITIKA etc. be Japanese and a small number of Taiwan investment manufacturers hand in.Ultrathin fabric weaving has many difficult points, wherein
It is restriction ultrathin fabric development that the left side warp tension (picking side) of warp beam is controlled, strand side is bad, split the exception such as bad selvedge, running occurred frequently
Prominent sex chromosome mosaicism.In this regard, glass cloth manufacturer researches and develops electronics using rotating speed, loss yields and cost substantial contribution is reduced
Side yarn tension controller reaches production purpose, but the yield of ultrathin fabric maintains a relatively low level all the time.
Existing ultrathin fabric weaving technology is grown up in the production technology and production equipment of thick cloth (such as 7628#),
Because its equipment and technologic inherent shortcoming make it be difficult to break through in the weaving of ultrathin fabric, inefficiency, cloth cover poor quality.
The invention discloses designed, designed selvedge tension control mechanism can effectively decrease or even eliminate strand side it is bad, split

Matter.
The content of the invention
Electronic grade glass fibre ultrathin fabric is commonly referred to as base and focuses on 30g/m2Below, glass of the thickness below 40 microns
Fiber cloth, the yarn that it is used usually below filament diameter 5um, the Tekes of number 5.5 (Tex) below, such thin yarn
High requirement is proposed to the preparation (whole slurry and through technique) before weaving, nonetheless by knitting after preceding process bands come
Continuous influence, still makes the woven strip of ultrathin fabric carry out tremendous influence.Superfine yarn is easily tangled mutually in whole slurry, lap wound, especially
, in the side Pan Chu (being attached most importance to left side disk especially) of beam of a loom, the warp thread for tangling was also easy to produce the phenomenon of pine or tension, when in weaving for it
When middle generation problems, because of the fluctuation of side yarn tension, left side twists side becomes extremely difficult.Twist the yarn line that side yarn is used
The 1/2~1/3 of density typically stitch yarn, superfine strand side yarn is very easily broken in the case of tension fluctuation, and then
The running of selvedge, to split the float such as bad selvedge i.e. inevitable.Such abnormal treatment needs to take a substantial amount of time, and loom efficiency is low
Under.There are strict requirements for the readability of fell as the glass jet shuttleless loom of main flow simultaneously, hightension, height are dynamic
Journey, high pressure are smooth woven premises, but simultaneously hightension, traverse high for superfine glass warp thread, particularly left side cloth
The warp thread injury of avris be also it is very serious, fabric width direction convergent force and warp-wise tension force and with knit tool between longitudinal direction
Under the collective effect of frictional force, left side warp thread can become to be very easy to fracture and fluff, and this will imitate the quality of fabric and weaving
Rate has no to ensure.It is the difficult point in a variety of tension forces more than improving, the present invention is using unique mechanism's design, and cleverly structure
Think of solves above-mentioned difficult point, enables ultrathin fabric scale of mass production, breaches weaving bottleneck.
The present invention needs the technical scheme to be protected to be：
Yarn tension controlling organization in side of the present invention includes left adjustment unit, right side adjustment unit, respectively positioned at a left side for loom
Right two avris, the left adjustment unit include again main burner 5, left scissors 4, adjuster 2, strand side yarn 3, fell (do not illustrate in figure,
Be known in the art term), fell base 10,
The active section of adjuster 2 is suspended from fabric, and its fixing end is fixed on fell base 10, and adjuster 2 will twist side yarn 3
The strand side of formation is limited in the inner cavity of its active section all the time, is consequently formed left cell to the pressure of cloth cover and spacing；
Warp thread passes through reed, reed to move forward and backward the fell side being positioned at first weft yarn between upper and lower two-layer warp thread
In boundary；
Picking yarn sprays to the right from main burner 5, through the fell that upper and lower two-layer warp thread is formed；
Described right side adjustment unit includes She Er yarns 9, abandons side yarn 12, fell base 10, right scissors 11 again, She Er yarns 9,
Side yarn 12 is abandoned to be all located on fell base 10；Twisted by She Er yarns 9 after throwing weft yarn run to the right side adjustment unit and form throwing
Weft tension, when picking yarn tension reaches loom control system preset setting value, loom system controls left scissors 4 to perform
Picking yarn is cut, tension force and the cutting of weft yarn is realized；Formed after cutting and new abandon side yarn；
The cloth surface pressure that side yarn forms right sided cell of abandoning of the same quantity for twisting is kept in She Er yarns 9, corresponding to left side list
The cloth surface pressure of unit, contributes to the plane control to fell and cloth cover；
Right scissors 11 be used to cutting it is first abandon side yarn, depart from from the original limitation ot it of She Er yarns 9；
After action cycle terminates, main burner 5 sprays new picking yarn to the right；
Under the synergy of left adjustment unit adjuster 2, balance is formed between the adjustment unit of left and right two, cloth cover is obtained
Excellent control, twist while yarn and while yarn be on same horizontal plane, twist side and obtain best protection, and longitudinal direction side yarn tension
Can be controlled, ripping be solved the problems, such as that side yarn tension is uneven.
Optimization design, the inner cavity of active section is designed to arc curve shape, it is ensured that the tension force energy of the strand side yarn 3 for contacting
Seamlessly transit.
Optimization design, the active section of adjuster 2 is suspended from the fabric near beat-up line.
Mechanism's design of the invention unique make strand while yarn and while yarn be on same horizontal plane, be in preceding dead point in loom
When (0 degree of angle), twist while yarn and while yarn be in tensioning state, such design can overcome the fluctuation of side yarn tension to be twisted for selvedge
The influence on side, it is to avoid split bad selvedge, twist the abnormal generation such as side bad, running.
The distinctive localized design of the present invention makes loom in high speed wefting insertion, can limit at the fell of left side warp thread in glass cloth width
In the presence of cross direction convergent force, rise or fall, reduce because its unsuitable forced position and caused by big traverse, high
The influence for fractureing and fluffing for left side warp thread under power effect, makes loom efficiency get a promotion.
When reed is interval in 0~180 degree wefting insertion, mechanism of the present invention can effectively reduce the side yarn caused by fell is formed
The problem that tension force is sharply increased, because when fell is opened, whole shedding motion runs up and down, now side yarn tension is maximum.Up and down
Limit to the inner cavity of the active section of adjuster 2 of left adjustment unit, thus reduce the traverse of side yarn, reduce side yarn tension, stretch
The arcuation inner cavity for entering the active section of adjuster 2 ensure that seamlessly transitting for tension force.When reed is interval in 181~360 degree of beatings,
Mechanism of the present invention can limit twist while yarn and while yarn breadth direction the free degree because fell close when, split is pushed away reed
Maximum breadth is will be returned under dynamic, side yarn tension is raised again, the increase of side yarn tension is reduced whereby, thus glass fibers can be improved
