Abstract

A method of making a seam for an endless woven multilayer papermakers fabric such as a press felt base fabric, comprises selecting a repeating weave pattern so as to provide during weaving a body portion woven as a double layer, and a shed change for the warp yarns adjacent to the warp yarns of the body portion to provide a first and second seaming portion. In each seaming portion the warp yarns are separated into an upper group and a lower group such that the weft yarn interweaves separately with each group to form a distinct upper and lower layer. A forming wire is provided at the vertically aligned lateral edges of the fabric, and the weft yarn in sequence interweaves with the upper group of warp yarns to provide the upper layer, forms a seaming loop about the forming wire and interweaves with the lower group of warp yarns to provide the lower layer. The method and a fabric made by the method provide improved uniformity of the seaming loops and reduced sheet marking in the seam area.
