Abstract (en)
[origin: US4279210A] A double-lock-stitch sewing machine in which the needle-thread loop on the underside of the workpiece on a stitching plate is engaged with a gripper thread by the rotating gripper associated with the bobbin housing for the bobbin supplying the gripper thread. According to the invention, in the path of the needle-thread loop in the space between the stitch plate and the gripper, there is provided a spring wire or rod which bears upon the needle-thread loop and prevents the formation of knots or bunching in the needle thread. The spring wire is fastened to the underside of the stitch plate on opposite sides of the needle hole and flanks the latter in its undeflected state.
