A seamed industrial fabric includes a base fabric formed from a material strip having a width that is less than a CD base fabric width. This strip includes longitudinal edges that are bonded to adjacent longitudinal edges to define an overall base fabric width. The strip includes generally MD oriented yarns held together by a fabric material component. Ends of the strip are joined along a CD join path to form a fabric loop with the generally MD oriented yarns being arranged in a true MD. The loop is collapsed so the MD oriented yarns form superimposed layers joined by bent-back regions of the MD oriented yarns that form seam loops that extend in the true MD at each fabric end. A pintle extends through intermeshed seam loops from the opposing ends to form a seam. The CD join path may be located on an internal surface of the base fabric.
