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. A process for making bulk textured material sheeting, comprising:

a) feeding a continuous supply of material sheeting to a texturing apparatus; and

b) repeatedly impacting the sheeting with toothed knives of the texturing apparatus, each knife creating a row of raised and pointed structures on the sheeting to texture the sheeting;

wherein step b) comprises actuating a first one of the knives downward and across the sheeting, and actuating a second one of the knives downward and across the sheeting in an opposing direction;

wherein each pointed structure has a finished height of between 150% to 300% of a thickness of the sheeting; and

wherein in step b), the sheeting is not perforated.

2. The process of claim 1, wherein the knives are actuated downward and across the sheeting to gouge the pointed structures out of the sheeting.

3. The process of claim 1, wherein the row created by at least one of the knives is continuous and substantially spans a width of the sheeting.

4. The process of claim 1, wherein the knives are arranged in one or more packs to form several rows of pointed structures in a single stroke.

5. The process of claim 1, wherein step b) comprises creating pointed structures on first and second opposed sides of the sheeting.

6. The process of claim 1, further comprising taking up the textured sheeting in a take up reel after the step b).

7. The process of claim 1, wherein step b) comprises actuating a first set of the knives generally downward and across the sheeting, and actuating a second set of the knives generally downward and across the sheeting in the opposing direction.
