International ClassD03D 003/04AbstractAn improved loop construction for use in closing the ends of an open papermaker's fabric is disclosed. The loop constuction, as disclosed, is elongated to achieve a minimum loop length of at least three millimeters. The loop is formed by an arcuate portion which defines the free end of the loop and adjacent 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. The continuous arcuate portion of the loop is within 15° of the perpendicular to the horizontal plane of the fabric. | |
