- Hello Mr Jongguran Sondang Doli Noviedo,
I have looked at your drawing but I cannot tell anything from it or about it. Is there a dancer or just a wire straightener?
I suggest you click on the "WAI STORE" on the left hand side and purchase the following books and articles:
Electrical Wire Handbook, Part 1
Electrical Wire Handbook, Part 2
We Do it Straight - Wire Straightening
Then start reading!
With regard to the second question, are you talking about capstans in a drawing machine? If so, you should be aware that a standard drawing machine is a non-positive device and thus more conductor is introduced to each drawing die than is necessary. This prevents wire breaks. The excess material slips back through the machine and the number of wraps is such to allow both the slip and the supply of conductor for the next drawing die. It is empirically determined.
- Peter J Stewart-Hay replied to the topic 'Manufacturers of Copper Tape welding machines' in the forum.The best longitudinal welding machine is manufactured in China and we hope the following contact information is still valid.
I suggest you contact Mr. Jimmy Jin once you have a proper technical specification. (Materials, widths, thickness range and so on.)
Mr. Jimmy Jin is the overseas agent for Chengdu Liachi Electrician Co Ltd Knowledgeable person at Liachi is Mr Liu Beihe.

Here is a quotation from July 2012
“We’ve supplied more than 80 sets of TIG Welding Aluminium Sheathing Lines to our customers. 15 sets of them were supplied to our overseas customers such as NKT Germany, General Cable Spain, France and Mexico as well as Thailand plants, VISCAS Japan, and other customers in India and Korea.”
Copper would also be TIG longitudinal welding process and should be no problem for Chengdu Liachi Electrician Co Ltd.
Nexans Kabelmetal also manufactured and sold longitudinal copper welding lines but their license is far, far too restrictive as far as sales areas, etc. We do not recommend them as a supplier.
