Drive and heater control year 1998:

 

Spinning section:

Speed adjustment for the extruder motor is done via a dc-convertor

To achieve a constant pressure at the extruder outlet, the output of the pressure controller is transmitted to the dc-converter to adjust the extruder speed.

The feedback of the actual extruder speed is done by a tacho generator mounted on the extruder motor.

One common frequency inverter supplies the synchronous ac motors for the spin pumps.

According to process conditions, the plc transmits the setpoint to the inverter.

All motors are equipped with an overload protection.

Solid state relays heat each extruder zone and spinning beam.

Each extruder zone and the spinning beam represent an independent control loop.

 

Take-up section:

The inverter unit is a processor-controlled static frequency inverter for powering the 3-phase motors.

All inverter units in a position cabinet are supplied with approx 570v dc from a common rectifier.

 

Heating system:

The heating unit rhu is processor-controlled.

The power supply is taken straight from 3-phase 380/400v which powers the cabinet.

The inductor is fitted inside the draw roll.

The rhu switches the current on and off in this inductor. While current flows, a voltage is inducted into the

Rotating draw roll.

This sets up a short-circuit current in the draw roll, thereby heating the roll unit.
