Abstract
1,110,051. Making nets: making non woven net-like fabrics: film extrusion dies: making reticulated films. T. J. SMITH & NEPHEW Ltd. 21 Dec., 1964 [25 Sept., 1963], No. 37808/63. Headings B5A and B5B. Net-like plastic material is formed by grooving a sheet 45 on both sides so that, at the cross over points 50 of the grooves 46, 47, the sheet is drastically reduced in thickness. The grooved sheet is then biaxially stressed or stretched, first in one direction (see Figs. 15-17, not shown), so as to cold draw the parts of reduced thickness into a fibrous state 52, and then in a direction at right angles, so as to split the sheet in the region of the fibre, and to distort the splits into shaped holes (see Figs. 19 and 20, not shown). The grooved sheet may be formed between helically or otherwise grooved rollers (Fig. 2, not shown), by extrusion through an annular die comprising inner and outer relatively rotatable rings 33, 34, having groove forming ridges 35, 36 (see Figs. 6 and 7, not shown), or by extrusion between two linearly reciprocable ridged die plates 42, 43, (see Fig. 9, not shown).
