<p>1,265,262. Non - woven fabric. ISERE-NORD. 2 Feb., 1970 [3 Feb., 1969], No. 4961/ 70. Heading D1R. A non-woven fabric is made by winding a thread 100 from a stationary supply around a pair of spaced apart thread supports 60, 61 using a thread guide 50 mounted on an endless flexible element 20 which moves in a substantially elliptical path, moving the thread reaches formed between supports 60 laterally along to form a sheet of weft threads, combining one or more sheets of warp threads 82, 84 with the wefts and securing the warp and wefts together. The supports 60, 61 can be helical springs which feed selvage threads 74, 76 into the weft sheet. The threads can be natural, synthetic or glass. The warp and weft threads can be secured by passing them through an adhesive bath and over drying rolls.</p> |
