1. Kòmanse ak chak pwosesis pre-pwodwi ak pwodwi semi-fini
1. For clearing the falling objects, by adjusting the distance between the a036 and a076 dust sticks, the falling object rate is changed from 2.57 percent to 4.43 percent ; for carding the falling objects, the falling object rate can be changed from 5.2 percent by adjusting the distance between the rear belly falling objects. into about 6.5 percent . After adjustment, the hemp rods and hemp skins on the yarn surface are reduced, and the chance of mixing during weaving is also reduced, which can reduce the "triple jump" defect by 20 percent to 30 percent .
2. Tise Rapier gen pi wo kondisyon sou bon jan kalite a nan fil orijinal la, mwens inegalite nan segman nan long, pi bon an. Anjeneral, li oblije 3 pousan a 4 pousan, valè cv uniformité a se 20 pousan a 25 pousan, ak valè cv fòs sèl fil nan 18 pousan a 20 pousan.
3. Amelyore bon jan kalite a nan jwenti a, longè fen a se jeneralman 1.5mm 4mm se pi bon an, ak jwenti a ak yon tòde gwo yo ta dwe espesyalman anpeche nan ti galon.
4. Warping requirements ensure "three spirits", that is, flexible rotation of tension ring, flexible braking, flexible automatic stop when broken ends, and at the same time slightly heavier side yarn, so that the tension of the whole warp yarn is uniform.
5. Amelyore bon jan kalite a nan gwosè, amelyore klè nan ouvèti chèn, rezonab chwazi gwosè a ak fòmile pousantaj la gwosè dapre varyete nan. Anjeneral, to a dimensionnement nan koton chanv se 8 pousan a 9 pousan, ki ka satisfè fòmasyon nan yon lis ak mete -fim dimensionnement rezistan sou sifas la nan chèn la. Pou kontwole kòrèkteman reprann imidite a, si imidite relatif nan atelye tissage a pi wo pase 80 pousan, reprann imidite a ka kontwole nan apeprè 7 pousan a 8 pousan; elongasyon nan gwosè a ta dwe rezonab kontwole, ak twal la gwosè yo ta dwe kontwole anba a 1 pousan; to amelyorasyon an se nan a ranje 10 pousan a 15 pousan, ki ka satisfè kondisyon ki nan twal tise rapier.
2. Yo ta dwe byen kowòdone distribisyon an nan ouvèti ak manje. Anjeneral, gen plis opòtinite pou fil sote domaj sou bò a nan feeder la trame. Se poutèt sa, diferan konfigirasyon ka itilize pou ajiste paramèt resi sou tou de bò yo. Tan an manje nan epe a trame se yon fason ki apwopriye avanse, pou ke nepe a trame ka antre nan yon bouch ki pi klè resi. Anjeneral pale, tan ouvèti chanv ak koton varyete yo ta dwe 290 degre -300 degre, ak tan an manje nepe se 70 degre -75 degre. Lè w ap manje epe a, pozisyon rapyè a manje trame se 4 a 6 moso gid lwen bouch la resi, ak pozisyon nan rapyè a resevwa trame se 2 a 20 degre lwen bouch la resi. 4 ray gid, epi tou asire ke nepe a antre tou dousman ak nepe a sòti byen vit pou ke nepe a gen ase tan yo pase nan kendo a klè epi redwi chans pou sote fil.
3. Ajisteman nan liy lan pozisyon chèn Ajiste wotè nan liy lan pozisyon, jeneralman sèlman ajiste wotè nan ankadreman an gout ak gwo bout bwa a dèyè. Lè ankadreman an gout ak gwo bout bwa a tounen leve soti vivan, diferans lan tansyon ant anwo ak pi ba fil chèn ogmante. Lè resi a tonbe konplètman louvri, fil chèn ki pi ba yo sere epi fil chèn anwo yo ki lach pou ke fil chèn yo respire ranje epi yo ka jwenn yon sifas twal pi plen. Si leve a twò wo, fil chèn anwo yo twò lach, ak fil chèn yo kole youn ak lòt, sa ki fè ouvèti a klè ak tendans so zetwal. Anjeneral, wotè gwo bout bwa a tounen nan varyete chanv ak koton se 70mm a 80mm, wotè nan ankadreman an gout se 30mm a 40mm, ak de bout yo ta dwe kenbe orizontal.
Fourth, the correct hanging heald specifications generally control the lower warp yarns to be slightly lower than higher. During the upper shaft and maintenance work, the lifting heald should be adjusted to ensure the "three alignments", that is, the alignment of the heald frame, the alignment of the tread bar, and the alignment of the tread plate and the rotor. "Siping" means that the heald frame (heddle bar) is flat, the lifting bolt is flat, the hanging heald plate is flat, and the stepping heald rod is flat. If it is unqualified, check whether the heald clip falls off, whether the top wire of the tread plate is loose, whether the bearing pad of the hanging heald is worn, whether the hanging heald belt is deformed, etc. Generally, the front and rear positions of the hoisting shaft are about 110mm to 120mm, the movement does not exceed 0.8mm, and the height of the hoisting shaft is 400mm to 410mm. The above measures have been tested on the GA747 loom for weaving 8s8s4238 hemp-cotton plain weave. The efficiency of the loom was increased from 50 percent to 65 percent , and the number of "three-jump" defects was reduced from 500 to about 200 in 90m cloth.
