ABSTRACT:
An apparatus for producing single-sided knurls on a web or substrate without heat. The apparatus includes a conventional knurling wheel and a knurling wheel having its points ground down. A nip is formed by these two wheels and an edge of the web is passed through the nip. The resulting knurl has raised features on only one side of the web. The knurls are thinner than conventional two sided knurls and minimize fluting to the web.
