Making mesh fibrillated sheets of polypropylene or polyethylene and their mixtures based on an earlier disclosure, applies controls and equipment for more economic manufacture than possible with prior art net technology

摘要

The new method employs plant for production of fibrillated sheet bands, by a combination of individual controls (in a broad sense), which are varied to affect: composition of the cited plastics and/or their mixtures; parameters of extrusion, stretching, fibrillating and winding-up of the sheet; and the machinery employed in the plant. An Independent claim is included for corresponding equipment, by implication.
