Machine plus a set of institutions, for equipment maintenance personnel , they also face a little more trouble, therefore, the cutting mechanism for adjustment allow the machine to play its due function.

When the cutting edge is not neat , in addition to checking the blade is not sharp and the right position of the left and right side cutter is correct, the position of the knife and movement travel is very critical, Although some instructions say that the lowest knife and the next bite amount of about 0.5mm, in the actual use, user found that the bite amount is 0, or the knife slightly raised a little higher, the work cut cloth effect is better. Interlock machine's cutter up and down based on the workers' gestures and the thickness of the fabric to set, generally workers like to raise the fabric or a little thicker fabric, to slightly increase the trip, otherwise it will cause the fabric can not enter the upper and lower cutter and cause poor cutting cloth. The adjustment of the moving can be set by moving pin 22 up and down in the long slot of crank 25 in Figure 1.

For some fabrics need to do double needles when the two traces appearing bulge, When it is not ideal to adjust the bottom thread threading cam to the loosest limit position of the bottom thread, the thin material needle plate can only be used to solve it. The bottom of the small part of the thin material needle plate (right in Figure 2) is thickened, which can loosen the bottom thread as much as possible and reduce the shrinkage of the cloth.
