scrap edge winding machine

• More stable tension closed-loop to ensure winding quality
  Using tension detection + closed-loop control (servo/frequency inverter), it maintains a smooth roll surface and consistent tightness even when metal strip thickness and hardness vary.
  It reduces issues such as edge wrinkling, loose winding, and telescoping caused by tension fluctuations.

• Hard rebound-resistant design for high-strength materials
  For the strong rebound characteristics of metal strips, the design optimizes the positions/angles of the guiding rollers, the pressing method, and the winding mechanism parameters to ensure the trim scrap remains stable during winding.
  It improves adaptability to changes in strip hardness.

• Strong guiding/alignment & correction capability (optional automatic edge guiding)
  With edge sensing and a correction mechanism, the scrap edge stays on a stable tracking path, reducing roll skew and lowering the difficulty for subsequent shearing and reuse.
  Suitable for applications with narrow trim width and scrap edge that tends to drift.

• High-speed stable winding with speed matching to the main line
  The system interlocks and synchronizes with upstream decoiling/slitting/trimming equipment to wind in step with line speed, reducing tension “pulling” impact.
  It lowers the risk of web breakage and material jamming, improving overall line throughput.

• Roll diameter / length (to-roll) control for easier downstream handling
  Supports roll diameter detection and length-to-position control (optional), with automatic stop at target length or roll-change prompts.
  Produces more uniform scrap rolls for easier storage, transport, and recycling/reuse.

• Wear-resistant structure with low maintenance cost
  Key bearings and roller surfaces are designed for wear resistance and anti-slip performance, suitable for metal dust and high-friction conditions.
  Simplifies daily maintenance and improves equipment uptime.

• Comprehensive safety interlocks and fault protection
  Safety strategies including web-break/overload/blockage alarms and emergency-stop interlocks ensure stable operation for both personnel and equipment.
  Clear fault indications reduce downtime and accelerate troubleshooting.

• Customizable winding solutions to match different scrap edge forms
  Provides single-station or dual-station solutions, as well as different core shafts/clamping methods, according to varying width, thickness, trim allowance, and winding diameter.
  Supports multiple winding cores and roll-type requirements.
