TOPIC: Twisting Machines Questions, help needed

Twisting Machines Questions, help needed 1 year 8 months ago #2439

Hi All!

I own a small audio cable manufacturer and I am looking for a machine to twist solid core wire with Teflon dielectric. I would like it to be able to handle 10awg to 30awg but it needs to be able a least 16awg to 24awg. Also is there a machine made that when it does the twist it does not torsion the individual wires? I am doing 500 - 1000m at a time, speed is not as important as consistency of twist and twist length.

Thanks
Chris Kline

Hi Chris,

I know exactly what you are looking for because 1n the early 1970s Maillefer (Swiss) made such a machine for pairs, triads and quads but unfortunately the machine was dropped from their product line in the 1980s. I think I can find a copy of the old Maillefer brochure so you will know exactly what I am talking about. Please E-mail me your E-mail address and I will see what I can find in our file system.

There is a small company in Germany that may be able to custom manufacture something similar for you but you will have to provide them with a detailed specification as far as wire sizes, dimensions over the dielectric. Maximum weight, gross and net, for the pay-off and the take up precision steel or precision steel/ plastic bobbins.

No doubt you are trying to balance the wire to wire capacitance and reduce crosstalk with other pairs in the same cable.

The German company is:

I was always quite impressed with their technical ability.

Basically you need a small planetary cabler to handle the torsion problem. Only real question that needs answering is the maximum number of conductors that you are putting together. 10-30 awg is probably too big of a range, but 16-30 is definitely doable.

Hi Chris,

You have actually a number of options regarding suitable machinery; however the final choice will depend on the no. of wires you wish to assemble, reel dimensions as well as overall product specifications.

As Eric already stated you can use a planetary strander which has a very low efficiency and will limit you both in product diameter and flexibility.

Another choice is a rotating take-up in conjunction with back-twist pay-off. This system is very flexible and will allow for short runs and quick change-overs.

A tubular strander or a bow cabler will also produce cables without introducing a twist in the individual conductor.

You can even utilize a double twist machine in conjunction with back twist pay-offs, very popular in the production of category cables, if your final product specification allows for some cold working of the individual conductor.

All of these systems will have to have very good tension control in order to produce high quality cables.

My gut feeling tells me that you will actually require a custom system tailored to your specific application.

In order to determine a suitable system for you let us know the number of wires to be cabled, reel dimensions, both for pay-off and take-up, and final product specifications you would like to obtain.

Feel free to contact us for more information.
