Abstract
A trimming device for sewing machines to trim the marginal edge of work fabric by a cooperation of a stationary blade fixed to the end of a projection arm, and a movable blade fixed to a drive arm positioned above the stationary blade. Between the projection arm and the stationary blade, is a gap for permitting the movable blade to move thereinto. The free end of a resilient plate, which is fixed at its base end portion to the projection arm, normally is substantially in the same horizontal plane as the end of the cutting edge of the stationary blade so as to cover and close the gap. The resilient plate is adapted to be contacted by the movable blade as the latter is lowered to be resiliently deflected into the gap and resume its original position as the movable plate is returned upward, thereby preventing the trimmings from coming into the gap.
