The causes and countermeasures of slitter deviation

Scuttling machine deviation refers to the phenomenon that part of the film on the end face of the film roll is wrong, which is caused by the slip of the film during the winding process.

Causes and countermeasures of slitter deviation:

1. Scuttling machine deviation and uneven end face belong to the same category of scuttling quality problems, in terms of degree, the deviation is more serious than the dislocation of uneven end face; In nature, the general uneven end face is a persistent problem, and the deviation is more accidental problems; From the reason analysis, the cause of uneven end face may cause the occurrence of deviation problem.

2. Because the misalignment degree is more prominent than that of the uneven end face, the focus of the analysis of the uneven end face should be placed in the fine, and the focus of the analysis of the uneven end face should be broadened, especially the influence of the factor of the cutting speed, acceleration and deceleration are too rapid, and the smooth film is easy to slip and cause mislayer, and the cutting speed should be slowed down.

3. Too tight film winding will also cause transverse slip of the film, and too loose film winding will cause air involvement, which will result in splintering of the end face of the film coil, and the winding tension should be adjusted.
