Presser foot with fabric guide and rolling element

Abstract

A presser foot that is adapted to extend forwardly upon attachment to a presser bar of a sewing machine that sews a fabric pressed under the presser foot includes a presser foot element that is pivotably attached to the presser bar and is biased pivotally with respect thereto by a spring, the element having a vertical slot with an open forward end and a rear end that is closed at a vertical needle-accommodating through aperture located ahead of a pivotal axis about which the presser foot pivots about the presser bar. The presser foot is formed with two recesses, one on each side of the forwardly open slot, each recess being longitudinally defined by outwardly extending flanges at each end, and a first pair of rolling elements that are rotatably supported coaxially by the presser foot element, one inside each of the two recesses about a common first axis that is disposed beneath the needle accommodating aperture, so that the rolling elements press on a fabric being sewn thereunder by the needle. In another aspect of the invention, the presser foot element is formed to have only one recess along a longitudinal side thereof, the recess being closeable by a securely attachable but readily detachable longitudinally extending plate.
