This situation is likely to occur at low speeds (around 250 m / min). The reason is that the normal use speed of the FA306 draw frame is 360 m / min or more, and the sliver is from an oval shape.
The front end of the exit comes out, and the chamfer is good here. At low speed, the sliver comes out from the side of the coiled tube oblique tube exit, and the chamfer on this side is small, and it is displayed as "mechanical wave" on the pop chart
It is actually a "circle effect" wave. --The coiled effect wave outputting φ400 cans is shown at 40cm and an integral multiple of 40cm, such as 80cm, 120cm, etc., outputting φ500
The coiled effect wave of the tube is shown at 50cm and an integral multiple of 50cm, such as 100cm, 150cm and so on.
Solution: Round the hard corners on the side. Or use the tray to pick up the sliver to make the Uster. If there is no wave, it means that it is a circle wave, if there is still, it means that it is a mechanical wave. in
Check rollers, rollers, roller bearings, gears, keys, keyways, etc. 80cm waves may be fundamental, and 40cm are harmonics.
