摘要：
In a method and apparatus for making a cross-laminated non-woven fabric composed of warp and weft webs (1, 2), the warp and weft webs (1, 2) are firmly gripped at least at their opposite selvages by and between the outer peripheral surface of a hot cylinder (3) and a pair of endless belts (8) as they are bonded together and heat-set on the hot cylinder (3). With this arrangement, the warp and weft webs (1, 2) are prevented from shrinking widthwise during heat-set on the hot cylinder (3).
