We have been producing hot air products for industrial needs for more than 45 years.



Optimal welding machine for advertising banners and car tarpaulins

Speed and temperature infinitely adjustable

Economic and user friendly

Can also be used for overlap welding, seam welding and piping welding


The Forsthoff-P2 is the manoeuvrable and lightweight hot air automatic welding machine ideal for advertising banners and car tarpaulins. Also suitable for overlap, hem and keder welding of tarpaulins made of PVC, PE or PP.

The FORSTHOFF-P2 welding machine is the efficient and manoeuvrable universal device for welding truck tarpaulins, tents, awning fabrics and advertising banners. The hot air welding machine produces overlap seams of 20, 30, 40 and 45 mm and can also be converted for welding in keder/pipe ropes. The machine can also be used to produce hems of 20 mm and 30 mm and 40 mm and 45 mm by simply fitting the hem welding accessory. Accessories for keder welding, roof welding and tape welding are also available for this machine.

The heating power of up to 4000 W 230 V AC can be adjusted to any temperature from 20 to 700 °C and can therefore be adapted to suit different materials. After the welding head has been pivoted in, the FORSTHOFF-P2 starts up automatically. Furthermore, the infinitely variable speed setting of the advanced motor generation with a running performance of up to 18 meters/min., in conjunction with the holding-down device, ensures wrinkle-free welding, that is to say an optimum welding result. The tarpaulin is also held securely in place by a three-point support.

Thanks to a new generation of nozzles, tarpaulin fabrics can be welded at a speed of up to 11 meters/min . Furthermore, the device has a stable carrying handle and a telescopic guide handle which can be individually adjusted to the size of the user. The agile and narrow housing design is ideally suited for the use of the FORSTHOFF-P2 in the car tarpaulin and advertising banner sector.
