Precision and quality

in one unit (motor and drive), while the BM 1250 adopts standard motors with drives installed in a cabinet on the cradle. Due to the compact structure of the slip-ring and brush-holder system, maintenance operations are reduced to a minimum. For all bunching machines, SAMP designs its own bows which are aimed at: • Reducing energy consumption thanks to the aerodynamic shape • Minimising the wear of eyelet and wire path • Diminishing the damage of wire surface, important for stranding electroplated wires (ie tinned, nickel plated copper, etc) • Decreasing the damage of insulated cores surface • Open bows are available with carbide or ceramic eyelets or rollers for bare and coated wire, aluminium wire, bare strands and insulated cores SAMP – Italy Website : www.sampsistemi.it

Automatic traversing adjust

FOR over 70 years SAMP has been developing and producing wire and cable manufacturing machines, which are synonymous with precision and quality of the final product all around the world. Extensive research and the continuous improvement of existing technology recently led to the development of the new SAMP double-twist bunching machine platform, which is designed for reels with a flange diameter in the range of 250-1,250mm and up to a total weight of 4,500kg when filled (in case of copper strand). In developing the new platform, the targets were: • Energy consumption reduction due to the implementation of low energy consumption bows • Ability to run the machine without human intervention thanks to the SAMP automatic traversing system, including: • Automatic detection of the reel dimensions

• Programmable strand tension by load cell dancer • Low preventive maintenance • Pay-off system integration with wire break detection • Energy efficiency architecture for high power factor (cosφ) • Unique drive and system control platform for all machine types • Integrated motor power unit installed inside the cradle for electronic machines • Communication based on safety integrated industrial wireless technology In the electronic series the drive system is based on an integrated motor power unit (IPU), installed inside the cradle. The drive system is supplied from the outside through a bus whereas all communications between the external control cabinet and the motors is based on safety integrated industrial wireless technology. The models BM 630 E, BM 800 E and BM 800 C have the IPU fully integrated
