Method for producing non-woven webs of cross-laid strands

摘要

A restrained web of orthogonal strands is formed by first traversing the strands according to the disclosure of U.S. Pat. No. 4,016,631 in a diagonal pattern with V-shaped reversals between two rows of strand-restraining elements along the selvedge of the web and then converting the diagonal pattern to an orthogonal pattern by forming an extended loop in each strand along the selvedge.
