Abstract
An expandable monofilament pintle, either solid or hollow, that is inserted in a channel formed by a plurality of intermeshed loops at the ends of a papermaking fabric is expanded by means of exposure to either chemicals, high temperature, or some other form of triggering mechanism to pull the fabric ends closer together to form a tight seam.
