Abstract
An improved method for reclaiming waste plastic materials generated during an extrusion coating operation. A rotating funnel or other device is used to gather the hot molten plastic waste material and twist it into the shape of a rope. The plastic rope is passed through a cooling bath and one or more pinch rollers. After passing through the rollers, the plastic rope is spooled, chopped, or fed to a plastics processing machine.
