Abstract
An improved method and apparatus is provided for use in a sewing machine. The improvements include preloading two pieces of material which are to be sewn together. The preloading is accomplished by positioning pieces of material to be sewn under a gripper spaced from the sewing head on a table while prior pieces of material are being sewn. The gripper engages the material and, when the prior sewing operation is completed, the gripper is moved across the table toward the sewing head to load the preloaded pieces of material. When the two pieces of material are preloaded, most of the material hangs over an edge of the table and the lengths of the pieces of material are determined by movable detectors.
