Abstract
A method of manufacturing a single use processing substrate includes the step of extruding a first layer having ridges and troughs between the ridges. The method further includes the steps of placing a second layer into the troughs while the first layer is pliant and compressing the pliant ridges so that the second layer is bound into the troughs.
Claims23
A method of manufacturing a single use processing substrate, the method comprising the steps of:
- extruding a first layer having ridges and troughs between the ridges;
- placing a second layer into the troughs while the first layer is pliant;
- and
- compressing the pliant ridges so that the second layer is bound into the troughs.
1 more element
An apparatus for production of a single use processing substrate, comprising:
- first means for extruding a first layer having ridges and troughs between the ridges;
- second means for placing a second layer into the troughs while the first layer is pliant;
- and
- third means for compressing the pliant ridges so that the second layer is bound into the troughs.
1 more element
A sheet material, comprising:
- a first cut-resistant layer having a plurality of projections extending away from troughs disposed between the projections;
- and
- a second layer of absorbent material disposed in the troughs and captured therein by overhanging portions of the projections.
