  • Patent number: 5382291
    Abstract: The decorations (6) made by the apparatus are realized by the use of solid particles (7) in the form of scales, sands or granules, which are deposited on and adhere to the hot tarred surface of the membrane (1). The apparatus includes at least one device for applying solid particles (formed by a rotating roller (10) or a rotating ring-wound continuous belt (14-17)or a rotatable plate (19)) provided with shapes (8) having a same shape as the final decorations (6) on the membrane (1) will have. The solid particles applying device is associated to a hopper (9) containing the solid particles (7) in such a way that the particles (7) fall by force of gravity from the outlet mouth of the hopper (9) onto the solid particles applying device and thence from the shapes (8) cut into the solid particles applying device onto the transiting membrane (1), forming the decorations (6) on the membrane (1).

  • Patent number: 4630565
    Abstract: The present invention pertains to an equipment adapted to uniformly spread anti-sticking powders, such as talc in an aqueous suspension, on bituminous membranes for water-repellent coverings in the building field. Said equipment comprises a series of rollers on which the membrane runs. During the feed motion the membrane passes through a suspension-applying station and a drying station. Downstream of the suspension-applying station, a flattened jet of compressed air eliminates the liquid in excess and creates a homogeneous liquid film on the membrane. Afterwards, the membrane reaches a rotating drum provided with suitably disposed shaped reliefs which, on the membrane itself, create a homogeneous distribution of the particles suspended in the liquid film.
