Abstract: The present invention refers to a composite support with fire resistance property for bituminous roofing sheaths. The composite support (9) comprises a first (1) and a second (7) layer of non-woven synthetic material met and a glass film (6) interposed between said layers (1, 7), between which a plurality of longitudinally oriented reinforcing glass filaments (4) are interposed.

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.
