supra pro


raveling Head SUPRA PRO HF Welder was developed specifically for production of large format Stretch Ceiling (French Ceiling) interior design elements.The machine is equipped with special high precision linear motion gear controlled by frequency inverter to achieve a perfect continuous weld "invisible seam" weld.


UPRA PRO HF Welder has universal application for both: PVC film welding and Harpoon welding with the use of special patented IAW™ "Inverted Airplane Wing" shape tooling. Optional vacuum work table and laser guides allow handling of thin films and precision positioning for fast production setup and weld.


he SUPRA PRO Traveling Head HF Welder has output power of 4kW, touch screen HMI, pneumatic press, automatic PLC steering control – electric motion system with electronically controlled movement counter controlling the length, traveled distance and weld cycle number. The HF machine is moving along the table on special precision rails allowing for smooth motion and exact movement/distance control. The machine is designed for medium size PVC films where cycle/spot or precise continuous line weld is required.


he machine can be easily upgraded and converted (if needed) into standard straight bar HF welder advertising banner/billboard HF welder or Keder production machine with the use of special attachment and electrode.
