ABSTRACT:
This invention consists of a pintle for use in closing the pin seam of an on-machine-seamed (OMS) press fabric. The pintle takes the form of a braided, knitted, or ply-twisted yarn whose components are monofilaments of various and/or varying diameter. It has an essentially circular cross section for ease of installation, but will flatten in use to an oblate shape closely conforming to that of the void shape formed by the loops at the end of the press fabric and leaving little or no gap when the seam is closed and under tension. Its porous structure allows the passage of water. In this way, the completed seam will more closely resemble the main body of the press fabric.
