Abstract

A papermaking fabric formed of warp and weft yarns woven endless in a multi-layer uneven weave pattern and heat set to produce set floats in the warp yarns of one length which appear on one surface of the fabric and floats of a different length which appear on a second surface of the fabric. A low profile seam for joining opposite ends of the fabric to form an endless papermaking fabric. The seam is formed by turning warp yarns back and reweaving them lengthwisse into each of the ends with weft yarns in such a manner as to present appropriate ones of the floats on appropriate fabric surfaces. At the same time, loops are formed along the ends in spaced manner. The weft adjacent the end comprise undersized yarns which are woven with the warp yarns to provide longitudinal space along the warp yarns and between the undersized weft yarns. This allows the formation of small loops at the ends by crowding the small weft yarns.
