4 SEGMENT SERVO DRIVE

All the key elements in the Speed frame namely, Bobbin, Flyer, Drafting and Bobbin Trough are driven by the Servo motors. With the above,

  • Main draft and Twist can be controlled through display
  • Flyer speed is maintained throughout the bobbin build through adjustable speed curve
  • Bobbin speed with bobbin build
  • Precise winding of bobbin

BOBBIN TILTING FOR MANUAL DOFFING

The machine is equipped with a simple individual bobbin tilting mechanism. When the trough moves down after doffing, a lifting mechanism makes individual bobbin to tilt forward. This tilting enables easy doffing of full bobbin. Thus ensures user-friendly doffing of full bobbins.

AUTOMATIC ROVING TENSION CONTROL

Roving tension is maintained at an optimal level by means of two Automatic roving tension controllers operated on CCD principle and through the individual servo motors. Automatic roving tension controller fine tunes bobbin drive and controls uniform tension throughout bobbin build which results in better stretch percentage values.
