Abstract: There is described a binding resin for nonwoven fabrics, in particular for manufacturing supports for bituminous membranes, consisting of 100% natural, sustainable raw materials. The resin is an aqueous solution consisting of starch, a crosslinking agent of natural origin and a catalyst.

Abstract: A substrate for a support for bituminous membranes, comprising two or more layers of fibers comprising a homogeneous mixture of organic fibers and inorganic fibers, between which there is interposed a reinforcing scrim, said fibers being oriented parallel to the longitudinal axis of the substrate and laid said by side and alternate.

Abstract: There is described a substrate (1) for a support (1) for bituminous membranes, comprising two or more layers of fibers (3) comprising a homogeneous mixture of organic fibers (31) and inorganic fibers (32), between which there is interposed a reinforcing scrim (4), said fibers (3) being oriented parallel to the longitudinal axis (L) of the substrate (1) and laid said by side and alternate.

Abstract: A reinforced textile support, particularly for bituminous membranes, made of at least one layer of polyester non woven web and continuous high modulus reinforcement yarns longitudinally set with respect to said layer. The reinforcement yarns consist of cellulosic fiber multi-filaments of the Lyocell type. The assembly is bound by mechanical needling or water entangling, stabilized by means of thermal treatment at a temperature of 200-250° C. and consolidated by means of a chemical binder.

Abstract: A waterproof sheet which allows for better adhesion between multiple waterproof sheets, the sheet including at least one layer of waterproof material arranged between a first and a second layer of spunbonded fabric, the layers of spunbonded fabric having a surface covered by waterproof material and being laterally offset one with respect to the other so as to have a projection of the first layer with respect to the second layer on one side and a projection of the second layer with respect to the first layer on the opposite side.

Abstract: A synthetic textile support for bituminous sheaths, particularly for the coating of roofs. The textile support consists of two layers of non-woven lap of polyester fibers, between which there is interposed a plurality of continuous polyester threads arranged parallel to one another in the longitudinal direction of the textile support.

Abstract: A machine for the formation of rolls of cotton-wool in compact form comprises a closed-loop conveyor belt having a horizontal upper branch on which there is placed a layer of cotton-wool to be wound. The machine includes a pair of support rollers for the horizontal upper branch, a first operator to execute displacement of the support rollers from a rest position with rollers reciprocally distanced to a working position with rollers reciprocally close to one another, the rollers passing through an intermediate position of partial reciprocal closeness. A support for a freely-rotatable core destined for winding up the cotton-wool and second operator that can be operated after the displacement of said support rollers in said position of partial reciprocal closeness to execute descent of the support of the core from a rest position above the upper branch of the conveyor belt to a position of partial lowering below the upper branch of the conveyor belt.
