Basic machine mechanisms such as: guide box, spindle, motor drive, tension-control system are compact. In the lower part of machine there is a spindle with a brake and a compensating and tensioning system. Feeding bobbin is placed on this spindle. In the event of exceeding the permissible tension of string, the tilting arm of the compensation and tensioning system causes immediate disconnection of the drive motor.

Precise winding net structure for various string thickness is achieved by varying the ratio between the screw shaft driving thread-guide and the spindle. This ratio is achieved by the selection of toothed wheels. The spindle is equipped with a vibration damper which guarantees the quality and hardness of the beam.

The machine is equipped with the following stretch and control elements:

• string missing sensor, sensor for exceeding the admissible string tension, beam diameter sensor
• wound-string length meter
• plate tensioner
