    Abstract: An apparatus for stranding an outer layer of wires on an inner layer cable core is disclosed. The apparatus comprises a tubular stranding machine comprising a rotating tube within which are stationary mounted on the same axis a series of cradles each supporting a spool of wire from which are paid-off the outer wires, means for guiding said outer wires along the outside wall of said tube towards a stranding die located at the front of the stranding machine, means for guiding a cable core originating from the back of the stranding machine along the outside wall of the tube, and a wire straightener stationary mounted at the front of the stranding machine ahead of the stranding die and through which is passed the cable core to eliminate the waviness of the cable core due to rotation during traveling along the outside wall of the tube.

    Abstract: A locking cable which is constructed of a plurality of separate strands with each strand containing a plurality of separate wires, each wire being between 0.005 and 0.012 of an inch in diameter. One side of the cable along its entire longitudinal length is stretched so that the material along that side is caused to exceed its yield point and be permanently deformed. As a result, the cable assumes a natural helical coiled configuration. A plastic cover may be applied to the cable in a close fitting relationship to help prevent the cable from becoming untwisted. The method of making the helical coiled cable comprises preforming and twisting of a plurality of separate wires together in a clockwise direction to form a strand, preforming and twisting a plurality of separate strands together in a counterclockwise direction to form the cable, and stretching one side of the cable along its entire length. An apparatus to perform the method of this invention comprises a pair of roller assemblies through which the cable is conducted with the cable being passed about a pin with an angular displacement exceeding 190*. The cable is passed through the apparatus in an extremely taut manner which causes one side of the cable to be permanently deformed.

    Abstract translation: 一种锁定电缆，其由多条单独的股线构成，每条股线包含多条单独的电线，每条电线的直径在0.005至0.012英寸之间。 沿着其整个纵向长度的电缆的一侧被拉伸，使得沿着该侧的材料被超过其屈服点并且被永久变形。 结果，电缆呈现天然的螺旋盘绕构型。 可以以紧密的关系将塑料盖施加到电缆上，以帮助防止电缆变形。 制造螺旋线圈电缆的方法包括将顺序方向上的多根单独的电线预成型和扭转，以形成线束，在逆时针方向上预成型和扭转多个分开的线束，以形成电缆，并拉伸一侧 的电缆沿其整个长度。 执行本发明的方法的装置包括一对辊组件，电缆通过该组件传导，电缆以角度位移超过190°的方式穿过销。 电缆以非常紧张的方式穿过设备，这导致电缆的一侧永久变形。
