Process for the continuous production of manufactured articles

Reticular structures comprising one or more fibrillated films perpendicularly arranged between two or more fibrillated films are prepared by a process comprising the steps of: feeding one or more fibrillated films onto a conveyor; feeding one or more transversal films perpendicularly to the conveyor feed direction; cutting such transversal films in position corresponding to the edges of the base film or films; suporposing to said transversal films one or more fibrillated films fed parallelly to the conveyor feed direction and causing the cohesion of the resulting composite structure. The device for producing such reticular structures is described too.

Reticular structures having improved mechanical characteristics

Device for the continuous production of manufactured articles reinforced

A process is provided for continuously manufacturing plates containing an open net fibrillated polymeric film reinforcement. A net having a plurality of fibrillated polymeric film layers is unwound from a continuous reel, and the net is cut into pieces having a length approximately equal to a circumference of a forming roll for forming a plate to be manufactured. The net pieces are impregnated with a cement mix and then deposited onto a conveyor belt on which a cement mix layer has been previously deposited. After contacting the net with the cement layer, the net is subjected to vibration. A vacuum is applied to the net contacting the cement layer to remove excess water and to increase the compactness between the net and the cement layer. The net-cement panel resulting from the above is wound onto the forming roll, which has a circumference approximately equal to the length of the net piece, with simultaneous application of pressure, so that the ends of the net piece are disposed adjacent to a notch located at a periphery of the forming roll. The net-cement panel is cut at the notch adjacent to which the ends of the net pieces are arranged to form a plate, and finally the plate is compressed.
