METHOD FOR JOINING ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE

Abstract of the Invention Articles for food use are made by bonding ultra high molecular weight polyethylene surfaces. The surfaces are cleaned to remove grease and dirt. The surfaces are immobilized in spaced relation to each other with a rigid support abutting the surfaces. The surfaces are soften...

Beschreibung
Zusammenfassung:	Abstract of the Invention Articles for food use are made by bonding ultra high molecular weight polyethylene surfaces. The surfaces are cleaned to remove grease and dirt. The surfaces are immobilized in spaced relation to each other with a rigid support abutting the surfaces. The surfaces are softened and a filler material surface softened with hot inert gas to make the outermost portion of each surface transparent. The filler material is pressed into the joint or gap between the immobilized surfaces. The article is cooled and removed from the rigid support surface.
