Preventive Measures For Quality Problems Of Webbing

Some webbing manufacturers in the process of producing webbing, there will be some conditions, resulting in insufficient product quality, Ribbon is widely used in clothing, industry, agriculture, munitions, transportation and other industrial sectors, so the quality of the ribbon production is related to the visual effect of the product, if the production of ribbon in which the problem, so it will lead to the scrapping of the product, then how to avoid these problems in the production process, improve the ribbon production pass rate, eliminate some manufacturers of trouble Next, we introduce some problems often encountered in the production process of webbing, and have corresponding solutions and preventive measures:
First, bend the belt
Formation reasons:
1, the uneven wear of the steel buckle 2, pan head drawing uneven 3, the steel buckle position is not correct 4, the yarn connection method is not correct
Preventive measures:
1, the steel buckle piercing method must be according to the regular piercing method, 1 group or 2 groups of piercing method. 2, the larger and looser side, pull off some, until it is as flat as the other side or less 1-5 laps. 3, the steel buckle is generally the distance from the knitting needle, there is a steel buckle empty distance. 4, according to the needs of the ribbon, points on the lower side, or points, left and right side, generally to point up and down, a strip if there are more than two practices or patterns, it is necessary to separate.
Two, the wave
Formation reasons:
1, the steel buckle wears uneven yarn, too much yarn on both sides, too little in the middle. 2, the steel buckle is too large, and the weft is too tight. 3, pan pull yarn is uneven, both sides pull tight, the middle pull too loose. 4, the bonding method is wrong, the balance of falling pressure is not good.
Preventive measures:
1, the selection of standard steel buckle, according to 1 or 2 groups of threading method. 2, according to the width of the ribbon needs, and then select steel buckle to wear. 3, the middle and both sides of the yarn to change a few, or the middle of the loose pull down some. 4, according to the webbing practice needs to be connected, the balance of the number of falling pressure average.
Three, the needle edge is bad
Formation reasons:
1, uneven weft thickness: 2, the needle on the wrong method, too long or too short 3, pan head walk is not normal, sometimes tight, sometimes loose. 4. The weft wheel is not round enough and has been deformed. 5, knitting needle fixed porch wear.
Preventive measures:
1. Replace the weft. 2, knitting needle according to the thickness of the ribbon on the long short, generally speaking, the length of the knitting needle, just the weft can be returned. 3, fix the two sides of the pan head, do not let the pan head against the two sides of the iron frame. 4, change the new weft wheel 5, change the fixed rod, or to process.
Four, hair
Formation reasons:
1. Needle edge fuzz. 2, fabric edge fuzz 3, webbing surface fuzz
Preventive measures:
1. The needle plate has been damaged for a long time. A new pin plate has been replaced; The needle has been damaged and replaced with a new needle; Press the tape plate too tight, relax the pressure plate; If the weft is not finished, adjust the distance between the weft needle and the knitting needle so that the weft can be finished
2, the weft hanging steel buckle, the weft into the weft rod; Steel buckle damaged, replace another steel buckle; The raw material itself has hair, if it is partially fuzz, replace the fuzz, if too much fuzz, do a full inspection belt after the goods are finished.
3, caused by damage to the weft needle, change one, or play with gauze; Damage caused by steel buckle, use gauze to play, or another steel buckle; The brown wire is damaged or the stop plate is damaged and replaced with a new one.
5. Size
Formation reasons:
1, the thickness of raw materials is uneven, so that the ribbon has a large and small. 2, the steel buckle is too big or too little, so that the webbing has size.
3. The weft wheel loosens during operation. 4, weft through the rod spring, there is yarn wool walking inside.
Preventive measures:
1, to often measure the width of the ribbon, found unqualified immediately adjusted to 2, wear steel buckle wear not too big or too small, wear unqualified again, can not be forced to produce 3, adjust the fixed weft wheel 4, often loosen the outside spring, so that there is yarn wool inside can come out.
Six, Yin and Yang color
Formation reasons:
1, raw materials have color difference. 2, pan head pressure is uneven 3, steel buckle wear uneven
Preventive measures:
1, change the hair or change the pan head without 2, the pan head weight. 3. Set the position of the weft needle in the middle of the opening.
Seven, jump needle
Formation reasons:
1, the stop rod is not blocked 2, the position of the weft needle and the knitting needle is not right
Preventive measures:
1, the position of the pin rod by the transport of the knitting needle 2, the weft needle and knitting to a good position, so that the weft can be all hung up
Eight, easy to dirty tape processing
Formation reasons:
1, the brown wire is too dirty 2, all the belt shaft is too dirty 3, all the yarn through the place is not clean enough
Preventive measures:
1, accessories room collar Kleenex and chalk, wipe the brown silk sheet clean. 2, scrub all the belt shaft clean 3, scrub all the places that have yarn through and can touch
9. Waves on both sides
Formation reasons: 1, the steel buckle is worn unevenly, the yarn on both sides is small, the yarn in the middle is more 2, the steel buckle is worn too small
Preventive measures:
1, choose the right steel buckle, wear according to the regular method 2, steel buckle wear a little suitable, do not wear too big or too little
Ten, lines
Formation reasons:
1, the bottom yarn is thick over the veil 2, the steel buckle threading method is wrong, the bottom yarn is not covered. 3, the choice of steel buckle is too thin, each empty to wear too much yarn.
Preventive measures:
1. Change the thicker bottom yarn to the very edge, or change it and add another one to it. 2, choose the appropriate steel buckle, 1 group or 2 groups of threading method. 3, under normal circumstances, try to choose 1 group or 2 groups of threading method, do not choose 3 groups or more.
