Abstract
An improved loop construction for use in closing the ends of an open papermaker's fabric is disclosed. The loop construction, as disclosed, is elongated to achieve a minimum loop length. The loop is formed by an arcuate portion which defines the free end of the loop and adjacent crossing portions which are interwoven with the fabric body in a repeated pattern. As a result of the disclosed construction, the continuous arcuate portion of the seaming loop is positioned vertically with respect to a plane through the horizontal plane of the fabric and the crossing portions are within 15.degree. of the perpendicular to the horizontal plane of the fabric.
