摘要：
A sewing machine having a presser bar and a needle bar and each having a force transducer mounted thereon for simultaneously detecting changes in load applied to the presser bar and needle bar. The force transducers are connected to a circuit including a computer for monitoring the fabric feeding and stitch formation forces encountered by the presser bar and the needle bar during sewing and analyzing the simultaneous force signal data from the force transducers on the needle bar and the presser bar of the sewing machine.
