Automatic welding machines

FORSTHOFF-D automatic hot-air welding machine


The new FORSTHOFF-D automatic welding machine provides the proven and robust FORSTHOFF technology for the welding of heavy thermoplastic canvases and foils.

It was possible to transfer the successful and proven design of the FORSTHOFF-P2 to the FORSTHOFF-D model. Therefore, FORSTHOFF now also offers a versatile and efficient automatic welding machine with state-of-the-art technology in the heavy canvas area.

The FORSTHOFF-D model produces overlap seams with a selectable width of 40 mm or 45 mm. The heating power of 4000 W, 230 V can be adjusted continuously from 20 – 700 °C and it can therefore be adapted individually to the different materials. The strong hot air fan with the FORSTHOFF Tube design produces a gigantic air power of 600 l/min and therefore supports the state-of-the-art gear motor powerfully in combination with the proven nozzle generation of the FORSTHOFF-D automatic welding machine. A service performance of up to 16 m/min can be achieved thanks to the continuous speed adjustment.

In combination with the hold-down device for crease-free welding, the canvas and roof canvas installer obtains an optimal welding result. The device starts automatically after the welding head pivots.

In addition, the three-point placement provides a safe contact pressure for the canvas. It is supported by the weight of the FORSTHOFF-D automatic welding machine, which is integrated in the housing of the automatic welding machine and which can be removed if required.
