how to make a PVC series belling machine for metal separation

SICA SpA

So Sica, Italian machine manufacturer, produced the first belling machine of this kind, Multibell 75Q. This is a very fast automatic belling machine specifically designed to receive PVC-U pipes coming from four-strand extrusion lines at independent speeds. It handles high production extrusion lines and can socket up to 1200 pipes/hour.
