Black Brothers RL-750 NL68 Rotary Laminator

***Manufacturer's Information:

From the manufacturer & Web:

The Black Bros. RL-750 NL68 is an industrial, heavy-duty rotary laminating press (pinch roller) engineered for continuous sheet-to-sheet combining of flat panels and overlays.

In the Black Bros. designation: RL-750: Denotes the rotary laminator series featuring 7.5-inch diameter nip rolls and pneumatic pressure cylinders delivering up to 2,000 lbs of total bonding force.

NL68: Indicates the nominal 68-inch roll face width, allowing it to process standard 4-foot (48″) and 5-foot (60″) panels with edge margin clearance.

Features & Specifications:

The RL-750 is primarily deployed in high-throughput laminating lines utilizing contact adhesives (solvent- or water-based), PVA, or polyurethane reactive (PUR) hot melts. It is frequently integrated inline directly downstream of a Black Bros. Model 775 Adhesive Spreader.

As panels exit the adhesive coater with face sheets placed, the pneumatic nip rollers of the RL-750 press out air pockets and deliver instant, uniform line contact pressure across the width of the board to establish an immediate bond without needing platen press cycles. Common applications include laminating high-pressure laminate (HPL), wood veneers, metals, vinyl, and linoleum to substrates like particleboard, MDF, plywood, foam, and honeycomb cores.

- Pneumatic Requirements: Clean, dry plant compressed air (typically 80–100 PSI supply to cylinders)
- Electrical Requirements: 208V / 230V / 460V, 3-Phase, 60 Hz (standard industrial line voltages)
- Footprint Dimensions: Approx. 88″–94″ W × 36″–44″ L × 58″–64″ H (base unit without attached infeed/outfeed conveyors)
- Approximate Weight: ~2,500 to 3,200 lbs (~1,130 to 1,450 kg) depending on frame configuration
