  • With TFD (double format winding) it is possible to roll up surface areas of approx. 450 m2 with just one EWA power drive. Central roller tube for more stability to wind pressure, less soiling of the sheeting, faster rolling speed and a combination of various types of sheeting and net fabrics possible.
