Abstract
An apparatus for producing an apertured plastic film having a tricot-like texture. The apparatus includes a film forming member comprising a rotatable hollow drum having a pattern of apertures and a topographical outer surface formed by a cluster of peaks and valleys surrounding each aperture. A plastic film is placed on the apices of the peaks and fluid streams are projected against the film while the drum is rotated. The fluid forces the film against the topographical outer surface of the drum causing the film to become apertured and to have a tricot-like texture corresponding to the pattern of apertures and peaks and valleys.
