ABSTRACT:
A device for operating and orientating a pair of automatic sewing machine needles have two needles which are locked to the lower ends of two equal rods, located beside one another in the vertical plane. These needles change over position during stitching without requiring reorientation of the needles themselves. The device has a cylindrical element movable in the vertical plane, which has the needles and rods therein. The device also includes a sleeve and guides for guiding the vertical movement of the cylinder, with driving means for driving the sleeve and cylinder such that the orientation of the rods is unaltered when they change over position. This enables the needles to operate in conjunction with the looper of an automatic sewing machine to which the device is fitted.
