Inline Thickness Control for film and sheet extrusion:
On the "control screen" of thickness gauge you see also thickness profile over bolt number (thermal bolts number), as well as set value. Set value must not be even. For every bolt can be adjusted a separate set value if required. With this feature dedicated areas can be produced thinner, for example where are knives for middle cut and edge trimming are located.
2. diagram shows actuating variables of every actuator (thermal bolts). If 100 % is reached, you have to readjust manually.
3. diagram shows various parameter of every single thermal bolt (scroll-able)
Automatic thickness control has one very big advantage: it is always present at the extrusion line and starts adjustment earlier than operators.
