ABSTRACT:
This invention relates to a dual clamping system for a sewing machine. The dual clamp system comprises a first clamp and a second clamp which may be used to clamp a first workpiece and a second workpiece, respectively, at a sewing station of the sewing machine. The first and second clamps are preferably of different shapes and dimensions so that different shaped workpieces can be clamped at the sewing station. In the preferred embodiment, the first and second clamps are adjustable inner clamps for clamping an inner portion of the first and second workpieces, respectively. The dual clamping system also comprises a peripheral clamp for clamping at least a portion of the periphery of either or both of the first and second workpieces at the sewing station. The dual clamping system permits an operator to either separately or simultaneously clamp and sew a plurality of workpieces having the same or different shapes.
