A method of weaving tubular textile articles, comprising: forming first, second, third and fourth superposed layers of warp threads; weaving by weft insertion through sheds formed in said layers, the weaving being performed by first and second weft threads inserted by first and second needles from one side of said warp layers; each weft thread being inserted alternately through a selected pair of said warp layers; and the weft loops at the other side of said layers being knitted together, the first layer with the second layer and the third layer with the fourth layer, to form a pair of selvedges. A tubular textile article formed by the method is provided. A needleloom for weaving such articles is also provided.

A method of forming an air bag which includes the steps of weaving on a loom an upper and lower fabric simultaneously, the two fabrics being combined in selected areas to define a seam of substantially circular shape. A bag is produced by cutting within the seam. The bag does not have an additional coating, but the permeability of the bag is determined by controlling the sett thereby utilizing the permeability of the weave itself.
