Slitting machine operating procedures -

Third, through the film:
1. The cutter exits to the stop position. (The split knife switch is in the off position)
2. Press the “Pinch with chain” button and the hook and loop on the chain will run to the feeding position.
3. Press “Release Brake” until the indicator light is on, and the unwinder brake is released.
4. Pull one end of the film manually, pull the film along the running route to the film-piercing mechanism, and fix the film to the shackle of the chain.

Causes, countermeasures and effects on the quality of BOPP film slitting quality ---

two. Wrinkle (wrinkle, vertical wrinkle, cross wrinkle, line wrinkle)
1. The effect of wrinkles on the quality of use
BOPP film is commonly known as "cellophane", which reflects the film's high stiffness, high transparency and good gloss. The film is wrinkled, which means that the flatness of the film is damaged to a certain extent. This is not allowed for any film. Not only will it affect the appearance of deep-processed products, but also cause quality defects in use, such as lack of coating, lack of printing, and so on. 2. Causes and countermeasures of wrinkles
The wrinkles caused by the slitting of the film have various forms such as wrinkles, longitudinal wrinkles, cross wrinkles, and line wrinkles, and the causes are also different, as follows:
(1) Wrinkle: also known as bottom wrinkle, initial wrinkle, etc., is the wrinkle appearing in the section of the original winding film of the paper core. Since the wrinkle is mostly irregular wrinkles, the user generally uses the film to wrinkle. Disposal. The degree of wrinkling is an important indicator reflecting the level of cutting technology of a BOPP film company. The film produced by different companies has a wrinkle length ranging from a few meters, tens of meters to several hundred meters, and the more serious the wrinkles, the more The greater the losses caused by users, therefore, each film company is committed to improving the research of slitting and wrinkle. Through many years, the BOPP industry has carried out a series of intensive and meticulous work on solving the problem of wrinkling. From the two aspects of process parameter screening and equipment adjustment and transformation, we have found a set of effective solutions and received very good results. effect,

Fives. Multilateral
Although the polygon and the end face are not the same as the faulty end faces of some layers of the film roll, the two are different. The unevenness of the end face is the jagged phenomenon that occurs when the film width is not changed, and the multilateral product The film width is slightly wider than the normal size.

1. Multilateral impact on quality of use
The impact of multilateral use on the end is basically the same as that of the end face, mainly to track the problem of alignment and the impact on the appearance of the product.
