Boosting coiling possibilities

SINGLE, double, fixed, expandable, vertical, horizontal, manual, automatic… Italian company DEM likes to offer more possibilities. The main distinction is in the coil axis. Wire can be wound up in horizontal or vertical coils, according to the material production flow. Horizontal coilers could have a fixed mandrel (BOM) or an expandable mandrel (BOH). The latter features an automatic opening/closing front door and automatic coil height pre-set adjustment to make all operations fast and easy and to increase uptime. It is provided with precision laying software that controls the sideways positioning movements with the rotation, to obtain a perfect traverse oscillated coiling of the wire. The BOH coiler can also be equipped with additional modules for coil ejection, and a tilting unit for fast coil removal. The family of vertical coilers includes the single-reel (BVS), double-reel (BVD) and double-reel with fully automatic coil change (VSA). The latter has a maximum capacity of five tons and a maximum working speed of 18m/sec. In its full configuration it includes the automatic strapping machine, aerial spool manipulator, weighing unit, and roller conveyors to load up to four spools and unload the empty spools (in case of collapsible spools). Haefely Hipotronics has introduced the latest addition to its 800 series DC Hipots with the digital 880PL-DC, ensuring simplistic operation, accurate results, and operator safety when testing insulation strength of electrical apparatus. This new design is claimed to have the highest output-to-weight ratio of any single-piece DC hipot on the market. The 880PL-DC is controlled by an intuitive, user-friendly interface dis- played on a large 7" colour touch- screen. 880PL-DC users can now program hipot test sequences in automatic mode or simply control the test voltage using manual mode. The 880PL-DC is also equipped with New addition from Haefely

All type of machine can coil flats, squares or round wires with speed synchronised with that of the line. Coilers are designed to have a heavy-duty structure. Rational design and the use of high quality components ensure reduced, fast and easy maintenance and long machine life. DEM Wire Rolling Technology has been a reliable partner in cold rolling lines for flat, profile and round wire since 1996. ❍ DEM: Expanding coiling possibilities

Excluding cold rolling cassettes and microcassettes, more than 290 mach- ines have been delivered since then. The company is moving on a solid basis and has lately attained a new goal. It has straightened its manage- ment and financial constitution, becoming a joint-stock company (Italian SpA).
