A non-vulcanized method of joining conveyor belt ends using metal fasteners (clips, staples, or hinged plates) that are driven through both belt ends and connected by a hinge pin or integral interlock. Types: (1) Wire staples/clipper — U-shaped staples driven through overlapping belt ends, economical for light duty, 50-60% strength. (2) Hinged plate — bolt-on metal plates with hinge pin (Flexco SR, Alligator, MLT MS), 60-70% strength, quick installation (30-60 min), easy for field repair. (3) Solid plate — riveted or bolted, non-hinged, 70% strength. Advantages: fastest installation (minutes to hours vs hours/days for vulcanized), minimal tools, no heat source needed, ideal for emergency repairs. Disadvantages: reduced strength (50-70%), shorter life, cannot pass tight-radius pulleys or cleaners smoothly, creates a "bump" at the splice. Selection per belt thickness, width, and tension. Per Flexco and MLT installation guides. Brands: Flexco (SR, Alligator), MLT (MS, Super-Screw), Mato. Replace with hot vulcanized splice at next planned shutdown for maximum life.
