US Patent:

40808785, Mar 28, 1978

Filed:

Jan 5, 1977

Appl. No.:

5/756786

Inventors:

Nicholas D. Gallagher - Troy OH
Richard L. Gibbs - Troy OH

Assignee:

The Brown-Bridge Mills Inc. - Troy OH

International Classification:

B31B 125

US Classification:

93 58ST

Abstract:

A method and apparatus for forming a compression scored release liner for use with a face stock carrying a pressure sensitive adhesive. The apparatus comprising a generally cylindrical roller having a generally semi-circular cross sectioned rib extending entirely around the surface of the roller concentric therewith, a pair of adjacent recesses forming relief areas extending entirely around the roller on either side of the rib, and a pair of lands each extending outwardly from the relief areas and forming the remaining cylindrical surface of the roller. The roller to compression scores the surface of a release liner in a controlled manner even though the thickness of the liner may vary, by providing relief areas and lands adjacent thereto on each side of the compression scoring rib so that excess material can be displaced from the scoring region in order to maintain uniform density of the liner in the scored region and prevent the rib from completely cutting through the liner.
