REDE DE MATERIAL SINTETICO A PARTIR DE PELICULA ESTICADA DE MATERIAL SINTETICO BEM COMO DISPOSITIVO E PROCESSO PARA A SUA PRODUCAO

摘要

A plastic net consisting of a pre-stretched plastic stretch film comprises pre-stretched bridges (7) and filaments (6), said filaments extending in a main direction (5) and being transversely folded in order to increase their tensile strength. The required reshaping of the original film material is performed by a pre-stretching device (9) with interacting rollers (10, 11) and a transverse folding device (20) with a reshaping area (23) in which the width of the filaments (6) is reduced.
