CARTACCI Ltd offers complete finishing lines, andcurrentlyhas inproductiontwo lines designed for an important Italian customer. Increased efficiency through innovation One line is to be used for the production of cylinders with diameters up to 235mm, and the other line is for the production of shock

absorbers with diameters up to 70mm. Both lines include pointing machine, drawing, straightening, cutting, chamfering, control, bundling, drainage, weighing and automatic wrapping systems. The equipment has been designed to limit handling and storage, both to ensure high productivity and quality of surface finish and to limit the use of manual intervention of operators thanks to its entirely computer- based systems. Cartacci has also introduced its straightening equipment to Canada. The straightening machine and its handling equipment were designed for welded tubes with upset ends, with a straightening process in hot conditions (up to 650°C). Operation of the straightener is based upon sophisticated logic and advanced technological solutions. Cartacci Srl – Italy Fax: +39 035 290514 Email: webmaster@cartacci.com Website: www.cartacci.com

SHUSTER-METTLER Corp, USA, is a manufacturer of tube, wire and shaped stock straighteners. The company has developed a series of self-feeding, high speed straighteners for use in the tubing industry, to straighten tubing in-line or from coils. The Shuster models 2GRS, 3GRS, 4GRS and 5GRS gear driven tube and bar straigheners do not rotate the material during the straightening process, but use eight vertical rolls and eight horizontal rolls to straighten and feed the tubing. The four models of powered straighteners cover thin wall tubing in sizes from 3.2 to 76mm (0.125" to 3") outside diameter. Straightening rolls are precision ground to size, in order to avoid deforming the tubing during the straightening process. The straighteners can be manufactured for speed ranges to meet the user’s requirements, up to a maximum production rate of 300m/min (1,000ft/min). Machines can also be manufactured to customer- specified pass-line height. For continuous straightening, a single motor and an AC inverter drive is used on all GRS machines. A servo drive is also available on these machines, for feeding precise lengths into a press or other inline
