There is provided a method of continuously forming a reticulated web. The method initially comprises providing a multitude of parallel thermoplastic filaments (17) in a side-by-side relation. The parallel filaments (17), are then directed into a nip formed by two embossing surfaces (12, 13). At least one of the two embossing surfaces (13) has a multitude of ridges (18) which extend for a sufficient distance so that the ridges (18) bridge two or more polymer filaments (17) in a direction at an angle transverse to the longitudinal direction of the polymer filaments. The filaments (17) are then embossed in the nip such that adjacent polymer filaments form (17) bond sites by polymer flow along the ridges (18). A multitude of these adjacent bond sites create a continuously unified reticulated web. |
