Learning from a proud history

same ergonomic reason it limited to 16 the number of wires which are drawn on a row. A higher number of wires would need a very long drawing shaft and would make it difficult and time consuming for the operator. There is the same range of wire contact pulleys for the annealer. The advantage of this choice is a much longer life of the pulleys which last, based on customers’ comparative tests, twice as long as the ones of other manufacturers, and also

maintenance is from the back of the machine; the gears are helical, hardened and precision ground for the best meshing. The forced lubrication of gears and bearings utilises a sealing system that is intrinsically safe which makes the contamination of drawing emulsion with lubricant oil impossible. Based on strict ergonomic concepts Trafco designed the drawing capstan area leaving ample room for the threading up of the line by the operator. For the

About 40 years ago Sictra first designed a multi-wire line with the intention of increasing the output of single wire lines by simply raising the number of wires simultaneously drawn. The company soon understood the essentials for multi-wire lines of concepts like productivity and efficiency. Its first priority was, and still is, to cut as much as possible any wire breakages, as the impact on the line productivity is much more harmful than in single wire drawing lines.

have a slower rotation speed, which has a positive impact on the life of the carbon brushes. Annealers for the medium and large range of wires are available both in vertical and horizontal execution for those customers who prefer easier access to the machine and accept the greater overall dimension in plan.
