FORSTHOFF-D – Overlap hot air welding machine for tarpaulins. An overlap welding machine for heavy webs

The strong and robust overlap welding machine for welding heavy plastic tarpaulins and roofing membranes.

The hot-air welding machine FORPLAST has a powerful drive motor and a very compact housing.
It is therefore suitable for heavy tarpaulins and films.

Even roof coverings can be applied safely on uneven surfaces thanks to the three-point support of the housing.

The heating power of 3400W 230V or optionally 4000W 230V alternating current is infinitely variable up to 700°C and, in combination with the infinitely variable speed setting, enables precise adjustment to the respective welding material.

The hold-down device on the side of the machine housing prevents the tarpaulins from warping.

The device starts automatically after swiveling in the welding head and produces overlap seams with a width of 45mm.

Thanks to its compact housing, the FORPLAST automatic welding machine is suitable for heavy tarpaulins, foils and roof coverings.
