ELTA High Frequency Welder is designed specifically for production of Conveyor Belts made of Thermoplastic Elastomers (TPE), PVC and PU. We offer the most advanced technological custom made tooling to make all of our flat belts endless easily in a minimal time frame. Endless joining and fabrications of various cleats, steps and sidewalls can be done easily with BELTA machine thanks to large welding table and electrode holder allowing positioning of tooling 360º circumference.

BELTA model is equipped with special quick change electrode holder. Side rolls mounted on the edges of the work table allow easy handling of long belts and precision weld positioning for fast production setup as well as ergonomic work space for operators.

With the use of touch screen HMI and programmable PLC operator can easily input multiple weld/seam recipes. BELTA series machines have HF power outputs from 6kW to 20kW for heavy production loads and various material thicknesses and cleat heights (10mm-150mm). All these options make this machine a perfect tool for high end production where precision, durability and strength is the key.
