ABSTRACT:
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.
