Extensive research and the continuous improvement of existing technology (over 70 Sampsistemi machines of this kind are currently in production) has improved the Double-Twist Bunching Machine BM 1250, which is designed for reels with a flange diameter in the range of 630-1250mm and a total weight of 4500kg when filled (in case of copper strand).

Some of the main machine features are large flexibility range of working section (1 ÷ 125 mm²); suitable for stranding copper and aluminium wires and laying up insulated cores; open bows with carbide or ceramic eyelets or ceramic coated rollers; high performance (up to 2000 TPM and linear speed 300 m/min depending on process); improved wire quality due to large pulleys diameter; optimal tension on the strand control due to built-in dancer; with electronic regulation via operator panel; drive architecture Premium Line for energy saving purposes; reduced preventive maintenance due to AC and brushless motors; and HMI colour touch screen 10” for line control.

The machine is positioned inside a hut-shaped protection that ensures sound abatement and accident prevention. In addition, a patented electrical cabinet placed inside the cradle includes all drives and I/O to manage all equipment inside the bows, characterizes the BM 1250. The communication between this cabinet and the main one occurs through a wireless safety integrated communication system.

The Sampsistemi manufacturing programme also includes a pre-twister, an equalizer and a wide range of dynamic and static pay-offs.
