Welding machines with continuous welding of R series welding speed of 5.5 m / min are suitable for large production. They weld quickly and efficiently regardless of the length of the bag. Machines designed for high quality manufacturing technology. The advantages of the machines are fully apparent in every difficult situation. The 500-R model permits the welding of parcels with products without a transport system, while parcels exceeding 1 kg require an additional TP-520 transport system.
