ABSTRACT:
An adjustable pile height mechanism for producing a tufted floor covering comprising an adjustable bed plate, a cam shaft, and a plurality of eccentric cams mounted on the cam shaft so as to contact the bed plate. The cam shaft is adapted to be rotated so as to rotate the cams, and the rotational movement of the cams raises and lowers the bed plate so as to adjust the pile height of the floor covering. A method for adjusting the pile height of a floor covering further comprises the steps of loosening the presser foot bracket bolt, raising the presser foot assembly, tightening the presser foot bracket bolt, disengaging the clamp assembly, rotating the cam shaft so as to adjust the bed plate to the desired pile height, engaging the clamp assembly, loosening the presser foot bracket bolt, lowering the presser foot assembly, and tightening the presser foot bracket bolt.
