Abstract
A presser foot assembly is disclosed which is operable to adjust the pressure applied to a fabric by a presser foot in a stitching machine. The presser foot assembly includes an adjustment element, a linkage and a presser foot. A connecting end of the presser foot is connected to the linkage. The adjustment element is operable to be adjusted while the stitching machine is operating, and adjusts the linkage such that the travel distance of a foot end of the presser foot changes. The adjustment element can include an adjustment eccentric, which adjusts the location of a cam. The linkage can include a cam follower, the height of a second end of which is changed when the cam is adjusted. The connecting end of the presser foot engages with the second end of the cam follower, and thus the height of the foot end is adjusted, allowing for more or less pressure to be applied to the fabric.
