  • Patent number: 4139141
    Abstract: A method and apparatus for manufacturing a spiral member by cold working an elongated strip comprising attaching one end of the steel strip to a mounting plate on a rotatable axle and driving the axle in rotation to wind the strip onto the axle to form a spiral member from the strip. The strip is guided as it proceeds for winding on the axle by two spaced guide plates on opposite sides of the strip so that each turn of the strip will lie adjacent the previous turn. The position of the guide plates is adjusted with respect to the winding of the strip along a line which forms an angle with respect to the axis of rotation of the strip. After the formation of the spiral member, it is drawn to a predetermined length.
