when the line jumped or breaked,what should we do?

Appear jump line, can find the reasons from the following aspects:
A, machine needle problem
(a) check surface line without wearing the wrong or less wear a thread a.
(2) check machine needle installation is correct, such as machine needle long slot put back or loading skew, etc.
(3) check machine needle model is applicable and needle bar regulating height are accurate, and check whether the machine needle point needle bar top. Machine needle installation too high or too low, will affect the hooks take line.
(4) check machine needle is distorted. Use distorted machine needle stitching, due to the formation of coil away from the hook, hook can't hook take suture. Mild bending machine needle is difficult to directly identified with the naked eye, can machine needle on the platform rotation, can distinguish.
(5) check the needle and the hook movement of the time is consistent. Machine needle and the movement of the time to fully cooperate with hook, hook can accurate hook take suture.
(6) check machine needle and sewing line weight is suitable. Large machine needle with young fine sewing thread can also lead to jump line. This is because the large machine needle stythe eye of a needle is longer, wider, thorn open fabric hole location is bigger, make the young fine sewing thread have larger space mobile, if exceed the scope of continually hooks, can appear jump line;
(7) check machine beard needle eye to have because bonding the chemical fiber sewing thread dust and congestion, so that the suture can't normal delivery, can't form coil.
Second, the presser foot problems
Check the presser foot is installed too high, the feed speed is too fast. Presser foot installation too high, can make the presser foot delivery fabric strength is insufficient, the fabric with presser foot shock, so that can't seal face line forming coil; Presser foot feed speed fast, in conveying fabrics, will surface line and fabric quickly away together. The hook can't hook live line.
Three, sewing thread problem
(a) check sewing thread is too coarse, degree of finish is not uniform or suture of quality of a material is too soft.
(2) check surface line tension is too tight. Line tension is too tight, in forming machine needle ring is too small, the hook can't hook take.
Four, other problems
(a) check whether hook defect. Defect of hook can't ticked suture.
(2) check needle plate hole is too big. Many manufacturers in the production of thin, unified change with small machine needle, no change in time matching needle plate. Partial large needle plate hole make fabric was machine needle into or out of round hole position, can't pressure sewing thread forming coil, can also lead to jump line.
(3) inspection feed dog, spindle bed are deposition have flocking dust, should pay attention to keep clean, so as not to affect the formation of stitching.
bolt
A, sewing thread problem
(a) check sewing thread quality if they are qualified. Mildewy, metamorphism or nodular suture the most easy to break.
(2) check chooses whether sewing thread and needle phase matching. Sewing thread is too detailed rules for tough insufficient dry; The young fine needle with too thick sewing thread, can make the sewing thread cannot smoothly through the pinhole and be cut out.
(3) check surface line tension is too tight. Tension is too tight, also easy to break.
(4) check machine pinhole is fill the sundry, lead to sewing thread delivery not smooth and fracture.
Second, the machine needle problem
(a) check whether appeared for needle thermal fuse suture phenomenon, particularly, in the use of chemical fiber suture, due to the sewing machine high speed operation, repeat biopsy needle fabric friction heating, melting point lower chemical fiber suture was striking.
(2) check hook position continually whether appropriate. The hook is too close to the pinhole, take line easy breaking suture.
Three, other problems
(a) check machine needle and needle plate is installed firmly. Loose machine needle or needle plate, can make machine needle and needle plate touch each other, and grinding section line.
(2) check all line after place (including a coil, stythe eye of a needle, hooks, needle plate hole, presser foot hole etc parts) if there is a bending, defect, avoid sewing thread was broke.
(3) to examine the bottom line drum winding line is too full or winding inequality, the bottom line is full or winding cylinder is uneven, the bottom line delivery not smooth, easy to cause the bottom line break.
In addition, operating workers gestures not beautiful or speed without rhythm, will pull fabrics and make the line was sent cloth teeth cut off, or to pick line hook up and down movement uneven and tear section line.
solution
Solve the jumper, break the problem at the jump line, break the caused reasons, respectively adopt different processing method:
A, for machine needle problem cause jumpers, break the solution
(a) don't pinpoint already blunt damage machine needle, to regular inspection, change in time.
(2) in the machine needle adding next to blow device, accelerate the machine needle heat dissipation.
(3) choose surface through special processing machine needle, as shown in figure 1 shows. The package is Teflon (Teflon) epithelial machine needle, in suture can reduce and fabric of the friction between the resistance, restrain machine needle produce high fever, prevent for needle thermal fuse suture and bonding fiber line crumbs, avoid jumper, break the wait for a phenomenon.
