Tubular stranding machine (Individual motor drive)

Introduction

TSF series is designed machine for official concentric stranding for class 2 conductor, widely used for steel core Aluminum wire stranding, Aluminum and Aluminum alloy wire stranding, copper wire stranding.

Machine adopt individual motor drive system, using different motors for stranding structure and traction unit.

Advantage

The pay off tension adopts magnetic powder brake or magnetic hysteresis brake,and it is adjusting through calculate the changing of wire quantity on the bobbin, this design can make sure constant tension control.

Adopting special big bearing structure with high rigidity.

Adopting precious metal electric conduction ring sealing design , the structure is compact so the feedback can be transmitted well.

The safety cover uses whole moving door which is controlled by pneumatic device. This design has good sealing characteristic and easy operation.

The whole line is controlled by separately motors, the pitch can be adjusted easily.

The special and advanced electrical system control make the pitch error less than 1.2%.
