Twisting, untwisting and straightening solve different preparation problems. End twisters tighten pre-stripped strands for the next operation; twisted-pair machines wind insulated leads together along their length. Network cable untwisters separate and straighten pairs for termination, while roller straighteners prepare rigid mineral-insulated and armoured cable. Select the required operation below. We confirm direction, working length and the finished wire condition using your samples, so a machine that twists a pair is not mistaken for one that opens it.
These machines include this operation as part of a wider process. Open the product page to check the complete working range and configuration.

For end twisting, define the exposed conductor length and how tightly the strands must gather. For twisted pairs, define pair length, direction and turns. For untwisting, show the pair separation and straightened length needed by your connector fixture. For MI cable straightening, provide the sheath material and accepted straightness. These four jobs use different mechanisms.
Watch the WM-4720 prepared-end twisting demonstration to see hand loading and the finished conductor ends. It demonstrates end twisting, not long-pair production or network-pair untwisting. For a separate single-spindle pair station, compare WM-4717. If solder is required, use our twisting and tinning selection guide to define the termination first. Send the wire sample, working length and required finished end for a trial.
| Required operation | Machine | Check before choosing |
|---|---|---|
| Open and straighten network cable pairs | WM-1216 | Required untwisted length and connector preparation; no cutting or insulation stripping. |
| Gather prepared conductor-end strands | WM-4720 | End preparation and twisted length; no full-length pair production. |
| Twist insulated leads along their length | WM-4716 | Parallel stations with configuration matched to the lead. Compare WM-4717 for a single-spindle station. |
| Straighten rigid MI or armoured cable | WM-9320 | Sheath construction and accepted straightness; a different process from strand twisting. |
WM-1216 separates and straightens network cable pairs for the next termination step. It does not cut the cable or strip its insulation.
These are different operations. WM-4720 works on pre-stripped conductor ends; WM-4716 and WM-4717 are for twisted-pair leads. Specify the required twist direction, length and turns for the sample trial.
Yes, selected cut-and-strip machines also twist the ends. The combined-process machines below link to their main product pages with the full working range; standalone twisting and untwisting stations remain separate choices.
