PROCESSOR CONTROL

All control loops are centrally managed.

The temperature control operates with automatic optimization which ensures a quick heating of the line.

All driving units are communication with the computer programmable control via a serial POWER LINK by which a high precision and short cycle times are obtained.

The following functions are performed:

The recipe managerment, the alarm managerment, the issue of reports for machine parameters(speeds, temperatures, stretching ratios).

The hardware consists of an industrial PC with display or screen as well as a computer programmable control.

Advantages:

All machine parameters for different tape qualities can be stored in the recipe management and can be called up immediately upon request. This allows the exact reproduction of a quality tape already supplied.

The control can be networked with a central data management system.

The control ensures also a precise production recording. Reasons for faults can be found easily.
