The Forsthoff-D roof welding machine is the optimal welding machine for welding thermoplastic roofing membranes. This apparatus is also suitable as an automatic overlap welding machine for welding heavy thermoplastic tarpaulins and foils.

The Forsthoff-D produces overlap seams of either 40 mm or 45 mm. The heating power of 4000 W 230 V is infinitely variable from 20 – 700 °C and can thus be individually adjusted to the different materials. The mounted powerful hot air blower Oval-AB produces a strong air output of 360 litres/minute.

In addition, the Forsthoff-D machine offers an advanced geared motor from Germany. Thanks to the infinitely variable speed setting, a speed of up to 16 meters/minute can be achieved.

In conjunction with the holding-down device for crease-free welding, the tarpaulin and roof tarpaulin processor obtains an optimum welding result. The apparatus starts up automatically after the welding head has been pivoted in. A three-point support also guarantees the tarpaulin’s secure pressure. This is additionally supported by the weight of the FORSTHOFF-D machine, which is integrated into the housing of the welding machine and can be removed if required.
