Plastic Sheet Manufacturing
When the film passing hot through the head of the extruder touches the cold rolls, a certain retraction is taking place. Due to that retraction a defective product is coming out. This is an undesired situation. Meanwhile, because of friction and heat, a high static charge is appearing.To remove the problem, DC charging bars are placed at locations where this retraction is happening.Accordingly, the sides of the film are pinned. After this process, static elimination bars are placed from both top and bottom of film so that undesired static charges are eliminated for a succesgul film winding ro roll.
