Barberan PUR-33-L

Barberan PUR-33-L

Barberan machine from 2007. This Barberan PUR-33-L is a continuous profile wrapping line designed for applying PVC foil, CPL, paper, and veneer onto various substrates using hotmelt technology. It features a robust, one-piece, electro-welded steel frame, motorized, rubber-coated feed wheels, and a slot-die extrusion system for precise adhesive application. If you are looking for high-quality wrapping capabilities, consider the Barberan PUR-33-L machine, which we offer for sale. Contact us for further details.

• Base frame: One-piece, electro-welded steel frame with high structural rigidity. Designed to absorb vibrations and maintain alignment of the pressure rollers.
• Conveying system: Motorized, rubber-coated conveyor wheels with inverter-controlled speed, ensuring precise synchronization between adhesive application and profile feed.
• Press/calender section: Universal supports and multiple pressure rollers with different shapes and hardness levels, suitable for complex profile geometries.
• System type: Slot-die extrusion system with adjustable lips.
• Working width: 330 mm.
• Gluing accuracy: Constant grams-per-square-meter distribution, independent of line speed. Closed system reduces oxidation, prevents premature PUR crosslinking, and minimizes material wastage.
• Adjustment: Micrometric lip adjustment for precise control of adhesive film thickness.
• Type: 20-kg PUR drum melter with heated plate, where only the uppermost layer is melted to preserve the chemical integrity of the remaining adhesive.

• Sealing system: Airtight design with special seals to prevent ingress of air/moisture.
• Pump: Integrated gear pump for a constant, pulsation-free adhesive flow to the applicator head.
• Function: Maintains the adhesive working temperature during transfer from the melter to the slot-die head at approx. 120–150 °C.
• Length: 4.5 meters.
• Technical features: Internal core made of PTFE (Teflon), high-pressure and PUR-resistant. Includes a uniform electric heating element to avoid cold spots, high-efficiency thermal insulation, integrated thermocouple, and temperature control via the machine PLC.
