  • Product Description

Core Engineering Features & Performance Advantages

Heavy-Duty Monolithic Base Frame

Constructed with a stress-relieved unified steel chassis integrating a large-capacity unwinding unit. Provides rigid structural damping against high rotational resonance, accommodating large master rolls up to Φ850 mm with continuous stability.

Independent Multi-Arm Winding Geometry

Each rewinding arm utilizes independent pneumatic-contact pressure regulation. This prevents cumulative tension variances across adjacent slit reels, eliminating core deformation and reel dish-out during diameter buildup.

Flexible Slitting Tooling Rail Assembly

Engineered with a modular tooling rail supporting quick lateral width repositioning. Allows rapid setup across multiple slitting widths, reducing changeover downtime while maintaining tight edge straightness.

Dynamic Closed-Loop Web Alignment (EPC)

Combines high-precision optical edge detection sensors with dynamic guide rollers to compensate for master roll telescoping. Delivers smooth web conveyance into the cutting station to achieve an operating product yield of ≥99%.

Frequently Asked Questions (FAQ)

Q: What makes the MG-1000DF particularly efficient for industrial-scale separator converting?

A: The machine integrates a rigid unified frame with large Φ850 mm unwinding capability and independent winding arms. This architecture maintains steady web tension and delivers a qualified product yield of ≥99%, significantly minimizing scrap losses in high-volume production.

Q: How does independent arm winding prevent tension variance between finished reels?

A: By assigning individual pneumatic control and torque regulation to each winding arm, every finished roll receives dedicated contact pressure, eliminating uneven winding tightness caused by subtle thickness variations across the master web.

Q: Can MEAREG customize the tooling setup for different slitting width specifications?

A: Yes. The MG-1000DF features a flexible knife assembly allowing rapid lateral adjustment. MEAREG provides custom-engineered tool holders, spacer sleeves, and full technical documentation to support flexible cell dimension changes.
