1. Install the fly sawing on the first puller head to cut on the profile stop marks or welding marks, in this way reduce the profile waste.

2. Double puller not needs to re-arrange the next extrusion time according to the no billet time in each cycle.

For the limitation of the running table 18m, maximum extrusion speed ≤35m/min.

The maximum return speed 220m/min.

Matching non extrusion time (invalid time: 14 seconds), In continuous production time within the extruder, extrusion machine tractor affect productivity, which is not allowed to wait for the tractor returned from happening.
