4. Select the corresponding winding station, adjust the pressure roller arm and pressure roller, and install the paper core of the corresponding specifications.
Reasons, countermeasures and effects of BOPP film slitting quality ---
eleven. Width deviation is too large
The width of the film roll is limited by the gap of the sipe roll. The actual slit width will deviate from the width required for the order, but the deviation should be controlled within the tolerance range of ±2mm required by the national standard. The so-called width deviation Large, that is, the actual width of the film roll exceeds the requirements of internal control standards or customer standards.
Not all products have a tolerance of ±2mm, and some customers can only take deviations from the film width, such as the Pd film of Kunshan Zhangpu, the LL film of Shanghai Zhicheng, the PL film of Beijing Amcor, etc. It is required to adjust the film width.

4 operational requirements
4.1 Preparation before cutting:
4.1.1 Before the cutting, the paper sent from the warehouse or the semi-finished products transferred from the previous process should be checked with the “production work order” to see if the paper quality, quantity, specifications, etc. meet the requirements of the work order. If problems such as quantity or quality are found, they should be promptly submitted to the dispatcher or feedback to the squad leader. After confirmation, the logo will be clearly marked and returned to the warehouse or semi-finished product area, and the qualified products will be re-sorted for cutting. If the feedback is not received, it will be deemed as acceptance. If there are quality problems such as insufficient quantity at the end, the personnel will be responsible.
4.1.2 Lubricate the equipment according to the maintenance requirements of the machine and check whether the safety protection devices of the equipment are effective.
4.1.3 Carefully check the quality of the front and back of the paper, graphics, paper, etc., to avoid the material specifications, model or quality of the products that are put into production do not match the requirements of the cut products.
4.2.1 Carefully check the accuracy and sensitivity of the electronic scale and vernier caliper, confirm whether it meets the requirements for use, and report the abnormality in time to report with the squad leader.
