Sica SpA, an Italian maker of downstream extrusion equipment, is touting its haul-off and cutting machine that automatically changes pipe diameter, in-line, without stopping production and with no intervention by the operator.
Sica calls it the FullAuto proc¼ess. Synchronization between the extruder and the haul-offs allows for control over the extrusion speed and the position of the caterpillars.
During the transition to a different pipe diameter, upper tilting caterpillars and electric position transducers help the FullAuto haul-off automatically recognize the in-process diameter change, and the machine repositions the lower caterpillars to keep the same extrusion axis.
The pulling force remains constant during the automatic diameter switch.
The cutting machine works independently of the upstream equipment, thanks to two electromechanical measuring systems that operate automatically. One detects the change in pipe diameter; the other registers the pipe speed and setting of the cut length.
Sica is headquartered in Alfonsine, Italy.
