Automatic straightening machines for ‘upset’ tubes

Cartacci Srl, Italy, has been operating for more than 40 years in the manufacture of automatic straightening machines. The company is now also a part of parent company, the Paccani Group. The most important developments in the design and manufacture of the company’s machines have been introduced during the last 10 years.

The experience accumulated during these years and the continuous technological improvements now form the basic principles of the automatic 10-roll straightening machine.

memorised by the machine in order to allow the operator to easily recall it for the next production run. The presence of 10 rolls also allows for an extremely versatile setup. It is possible to achieve five different settings, each corresponding to the particular target quality in order to achieve specific tube characteristics. The other important innovation of Cartacci is the introduction of a new family of straightening

machines, designed for ‘upset’ tubes. Operation of these machines is based upon sophisticated logic and advanced technological solutions. The fast opening/closing of every roll mechanism allows for an efficient passage of each ‘upset’ configuration, with the maximum straightening capability on every length of tube. The Cartacci straightening machines have found a good use in many sectors, with adaptability for tubes in steel, zincked steel, brass, aluminium, and gold. The machine can also accommodate tubes at 650°C,
