ABSTRACT:
A universal sewing foot, for a sewing machine having a skipping top transport and a skipping bottom transport, comprises an advancing foot and a holding foot which alternately engage the workpiece. A locking member selectively locks the holding foot so that it operates either in a non-skipping mode, in which the foot is urged downward against the workpiece by a spring, or a skipping mode, in which the foot is locked to the skipping upper transport with the spring under compression.
