Hot laminating machine BL-2500

coldroll-to-rollindustrial

Overview
The Crest BL-2500 is a heavy-duty wide-format cold laminator with a 2500 mm working width, engineered for single- and double-sided lamination, roll-to-roll, roll-to-sheet, mounting and liquid silicone processes. A 1500 kg frame with 15 mm steel side frames stabilizes the 222 mm laminating rollers across the full width. Two winding positions top and bottom, autogrip shafts and roller pressure up to 5 N/mm enable versatile production workflows.

Applications
01 / Large-format lamination
The BL-2500 laminates and mounts up to 2500 mm wide in a single controlled pass, avoiding splits or tiles. Adjustable roller pressure up to 5 N/mm and digital nip measuring keep edge-to-edge consistency.

02 / Double-sided lamination
With two winding positions on top and two on the bottom, film can be applied to both sides simultaneously. Optional Combi Windup/Windout with adjustable brake and wrinkle control maintains flat, even films across the width.

03 / Liquid silicone processes
When fitted with the optional chrome top roller, the BL-2500 spreads liquid silicone evenly over 2500 mm. An 80 mm roller nip, electrical height adjustment and handwheel fine-tuning control the process for thick rigid panels.

Built for wide-format production
The machine keeps control of pressure, tension and film flatness at 2500 mm. Rollers are stable thanks to two 15 mm steel side frames and a 1500 kg body. Speed is adjustable up to 8 m/min forward and reverse. A swing-arm control panel moves between top and bottom working positions and a foot pedal allows hands-free start/stop.

Best suited for

• Display, signage and exhibition producers handling panels and prints wider than 2150 mm
• Industrial finishers applying protective film to one or both sides of wide sheets and webs
• Face-mount specialists working with liquid silicone on oversized acrylic and glass
• Converters switching between roll-to-roll and roll-to-sheet workflows on the same machine
• Operations requiring repeatable pressure and nip settings
• Production floors needing a heavy, stable machine (optional casters with anti-vibration feet)

Configuration options
The BL-2500 starts as a heavy-duty cold laminator and can be configured for specific processes. Options include heated top and bottom rollers (up to 135 °C), chrome top roller for silicone laminating, bottom autogrip shafts, Combi Windup/Windout with adjustable brake and wrinkle control, and caster wheel set with anti-vibration feet. Additional winding and guiding configurations available on request.

Suitable materials

• Wide-format prints
• Rigid boards and panels
• Clear acrylic panels
• Glass panels
• Liquid silicone
• Pressure-sensitive overlaminates
• Protective films
• Mounting films and adhesives
• Thermal lamination films
• Roll materials and sheet materials
• Custom substrates on request

Operation and safety
Safe operation from both sides is provided via the swing-arm control panel. Photocell finger protection guards the roller nip front and rear. Stop bars on both sides halt the machine and lift rollers automatically. A foot pedal controls start/stop. Autogrip winding shafts speed roll changes and a removable splitter/guide roller allows flexible material paths.
