    Abstract: The present invention provides an improvement in a clipper seam used to join the ends of a fabric belt to form a continuous conveying member. The seam is formed using an array of P-shaped loop members having a barb on the shank ends thereof. The loop members have two different lengths and are placed along the terminal end of the fabric in an alternating array to distribute the transferred load over a greater surface of the fabric. The barbs engage the fabric and an adhesive is applied to the fabric over the shanks of the installed loop members. The ends of the fabric are brought together to form a continuous belt and a pintel is installed into the P-shaped members to join the two ends.
