Abstract

An improved device for operating a needle in a sewing machine having a needle-supporting clamp (2) that is guided for sliding movement in a vertical plane by a needle bar (4). The needle bar (4) is pivotably mounted on and depends from an adjustable support (16), which causes the needle bar to automatically align itself and follow the effective path of travel of the needle-supporting clamp (2). The support (16) is mounted on the machine frame (1) and is eccentrically positionable, which provides a means whereby it can be selectively located in a position at which the needle bar (4) depending therefrom will never be subjected to more than a minimum amount of resistance by the needle-supporting clamp (2) during the sliding movement of the clamp on the needle bar.
