Contact us for further details. • Base Frame: One-piece electro-welded steel frame with high structural rigidity. It is designed to absorb vibrations and maintain pressure roller alignment. • Transport System: Motorized rubber-coated feed wheels with speed controlled via inverter, ensuring precise synchronization between glue application and profile feed. • Pressing / Calendering Zone: Universal supports and multiple pressure rollers with various shapes and hardness levels, suitable for complex profile geometries. • System Type: Slot die extrusion system with adjustable lips. • Working Width: 330 mm. • Glue Application Accuracy: Constant gram-per-square-meter distribution, independent from line speed. Closed system reduces oxidation, prevents premature PUR crosslinking, and minimizes material waste. • Adjustment: Micrometric lip adjustment for precise control of glue film thickness. • Type: 20 kg PUR drum melter with heated platen, where only the top layer is melted to preserve the chemical integrity of the remaining adhesive.
