1.High-speed filmSlitting machineCauses of loose or tight film rolls
1.Slitting machineImpact of parameters
Factors such as unwind tension, rewind starting tension, pressure, and their curve settings;
2. Impact of film characteristics
The influence of factors such as film thickness, haze, roughness, and shrinkage rate must be set according to the characteristics of different films;
3. Impact of rewind speed
When the rewind speed is slower, there is more time during the slitting process to expel air from the film roll, resulting in tighter winding of the film roll;
4. Impact of product specifications
Rewind length, roll matching, etc.;
5. Impact of slitting equipment performance
Adjustability, stability, operability, etc.;
6. Impact of operational factors
Professional level, operational skills, work responsibility, etc., generally reflected in issues such as incorrect pipe connections, poor adjustment of the rewind clamp position, and unbalanced rewind pressure rollers;
7. Impact of environmental factors
Temperature, humidity, etc., do not arbitrarily open the purification room door;
8. Impact factors of assessment system
Operators, considering the workshop's assessment of slitting indicators, often adopt a strategy of winding tightly rather than loosely, which is one of the factors causing the film roll to be wound too tightly.
