• 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.
• Sealing System: Airtight design with dedicated seals to prevent air/moisture ingress.
• Pump: Integrated gear pump providing constant, pulsation-free adhesive flow to application head.
• Function: Maintains adhesive working temperature between approximately 120–150 °C during transfer from melter to slot die head.
