ABSTRACT:
A web of fabric material is fed flat along a substantially horizontal table. The web is continuous and is marked and then partly cut just short of its edges while in the feeding plane. The edges of the web are then gripped, moved together, and overlapped as the web is moving, and the edges are sewn. A moving gripper pulls the web through the apparatus to an off the arm sewing machine, and a puller roll downstream of the sewing machine assists pulling of the web and maintains the seam tensioned during sewing.
