Method for mechanically embossing a surface covering using a recyclable solidified slurry embossing tool
View Patent ↗Disclosed is both a method and apparatus for mechanically embossing a surface covering. The apparatus includes an embossing tool comprising a slurry. The slurry includes both a filler and binder. The method includes printing a slurry onto a surface covering and compressing the slurry onto the surface covering to create a mechanically embossed texture onto the surface covering.
1. A method of mechanically embossing an article comprising applying a recyclable and reusable slurry in a pattern onto a backing, soliditying the slurry, pressing the slurry into the article to mechanically emboss the article, removing the slurry from the backing and article after embossing the article, and then reclaiming the slurry.
2. The method, of claim 1 , wherein the backing is selected from the group consisting of a belt, a drum, a roll, a plate and combinations thereof.
3. The method of claim 1 , wherein the slurry is applied by screen printing onto the backing.
4. The method of claim 1 , wherein the slurry comprises a filler and a binder.
5. The method of claim 4 , wherein the binder is biodegradable.
6. The method of claim 1 , wherein the slurry is applied in register with a printed pattern on the article.
7. The method of claim 1 , wherein the article is chemically embossed.
8. The method of claim 1 , further including imparting a differential gloss on the article.
9. The method of claim 1 , wherein the article is a surface covering.
10. The method of claim 1 , wherein the solidified slurry is in direct contact with the article when it is pressed into the article.
11. The method of claim 1 , wherein the portion of the article into which the solidified slurry is pressed is gelled prior to the solidified slurry being pressed.
12. The method of claim 1 , wherein the portion of the article into which the solidified slurry is pressed is cured prior to the solidified slurry being pressed.
13. The method of claim 9 , wherein the surface covering is a floor covering.
