Direction of impact
The direction of rotation of the stranding cage of a stranding machine determines the direction of lay. A distinction is made between right-hand or Z lay, which corresponds to the right-hand thread of a screw, and left-hand or S lay, which corresponds to the left-hand thread of a screw. Stranding assemblies consisting of several layers of stranding usually have an alternating lay direction of the individual layers for better dimensional stability and flexibility.
