Abstract
For use with a mandrel supporting a plurality of cups, an improved pipeline pigging cup is set forth in the preferred and illustrated embodiment. The cup is equipped with a large protruding lip around the periphery, and has a reinforcing member in the lip to secure the lip in a resilient fashion against the surrounding pipeline. The reinforcing member is formed of a strip of cloth backing with upstanding staples in the form of a multitude of small staple tips; the tips are arranged at or near the surface of the lip, thereby defining an abrasion resistant surface.
