Bunching machines

With decades of experience in the wire and cable machinery, SAMP provides a complete range of bunching machines for stranding copper, aluminum, and their alloys, as well as for laying up insulated conductors. These machines are designed to meet the demands of the cable industry, ensuring high quality and exceptional performance.

Bunching machines for bare and tinned copper wire are engineered to produce concentric strands,19-wire unilay and 37-wire cords, as well as double-twist strands for insulated flexible or rigid conductors.

Key advantages

• Compact design: optimizes floor space in production.
• Low energy consumption: thanks to high-performance motors and bows.
• Flyer and dynamic motorized pay-offs with accurate wire-tension control
• Large diameter ceramic rotor pulleys: ensures optimal bunching quality
• Quick cable connection of bunching machine to control cabinet
• Limited number of brush collectors: reduces maintenance requirements
• Available SAMP tube-type closed bows: enhances operational efficiency
• Line direction flexibility (L → R and R → L): allows seamless integration with existing production lines
