    Abstract: The invention relates to a method and apparatus for measuring lay length of a wire rope having a number or external strands to form a rope having spiral grooves in the surface between the strands. A magnetic flux circuit is generated, part of which is formed within a region of the advancing wire rope. Variations of magnetic field around the region of the rope or variations of magnetic flux entering or leaving the rope are sensed by at least two sensors arranged around the rope. Signals from the sensors are subtractively combined to eliminate variations due to off-axis movements of the rope, and the combined signals reveal an oscillating pattern due to the undulating surface of the rope. Linking the oscillating pattern to distance along the rope reveals the lay length, which corresponds to a number of oscillations which is the same as the number of strands at the surface.

    Abstract: A method of stranding elongated elements into a strand of reverse twists according to the invention is based on that, that a bundle of elements is inserted into a winding flyer (7), producing the first twist in the bundle and winding the bundle on a drum (9) which acts as an accumulator. Simultaneously, the bundle is unwound from the drum (9) by means of an unwinding flyer (13), producing the second twist in the bundle. Next, the bundle is pulled out of the unwinding flyer (13). Both flyers (7, 13) and the drum (9) have a common axis (O) of rotation and rotate in the same direction. A repeating period of stranding the bundle of elements consists of at least two successive phases of twisting. A length of the bundle twisted in one phase by the winding flyer (7) is next twisted in another phase by the unwinding flyer (13). The strand of the bundle is an algebraic sum of successive twists produced in particular phases of twisting. It is advantageous if the twisting as above is repeated.
