Abstract

A process is provided for making bulk textured material sheeting. As a continuous supply of flat material sheeting is fed, the sheeting is repeatedly impacted with toothed knives, each knife creating a row of raised and generally pointed structures on the sheeting to texture the sheeting.

Claims

1-24. -24. (canceled)

25. A material comprising:

a metal sheet having first and second opposed sides, and a thickness between the first and second opposed sides; and

a first plurality of raised and pointed structures gouged out of the first side of the metal sheet, wherein the sheet is not perforated, and wherein the raised and pointed structures of the first plurality have a height of between 150% and 300% of the thickness.

26. The material of claim 25, wherein the raised and pointed structures are arranged in a plurality of rows.

27. The material of claim 25, wherein the raised and pointed structures have a height of less than 0.0100 inches.

28. The material of claim 25, wherein the raised and pointed structures have a height of between 0.030 inches and 0.070 inches.

29. The material of claim 25, further comprising a second plurality of raised and pointed structures gouged out of the second side of the metal sheet.

30. The material of claim 29, wherein the raised and pointed structures of the second plurality have a height of between 150% and 300% of the thickness.

31. The material of claim 25, wherein the raised and pointed structures have a hook shape.

32. The material of claim 25, wherein the metal sheet is in the form of a roll.
