Operation Principle

Operation Principle
The CONTGRAV system was designed to control the linear weight and the regularity of extruded materials through the control of the haul off speed or the control of the rotating speed of the extruder screw. The operator can program the required linear weight in grams/meter. The CONTGRAV continuously measures with high accuracy the raw materials throughput at the inlet of the extruder screw (kg/hour) and the actual haul of speed (meters/minute). It is therefore possible to compare the linear actual weight with the programmed value and adjust speeds to meet the required value.

For thickness control it is sufficient to keep the external dimensions constant, like for instance the external diameter.

This principle of gravimetric control assures that the linear weight and the thickness of the extruded material is not affected by variations of apparent density of raw materials, fluctuations of the power supply voltage, variations of the screw rotating speed or haul off speed.

The CONTGRAV system is easy to integrate and to install in any extruder. it is delivered with all accessories, including a tachometer, motorized potentiometer and/or terminals for the motor speed control.

This equipment is able to detect any malfunctions and anomalies. In these cases an alarm will be activated.

Programming and Settings
The linear weight can be programmed directly on the control panel through a remote computer (option). Machine status, control and production parameters are permanently displayed.

Besides the indications of the throughput, speed and linear weight there are also control counters for total and partial weight and length.

Accuracy, quality and productivity

The CONTGRAV system assures an accuracy higher than 0,5%. In the case of extruded films it is possible to achieve raw materials savings of about 10%, due to the reduction of the average thickness and the attained regularity of the extruded product. Our experience in this field did show us that it is possible to obtain even higher savings, particularly in cases where non-systematic manual control was formerly used.

Thanks to the obtained regularity of the extruded materials is it possible to improve the quality of welding and the associated production rates.
