Abstract
A rotary drum washer-extractor having an abrasive structure therein for treating fabrics or garments in a wash medium and a method of abrading fabrics or garments employing the abrasive structure to produce a controlled abrasion of the fabrics or garments are disclosed. The abrasive structure is formed preferably of a corrosion resistant material wherein the material forms an abrasive surface affixed to metal surface by a molten metal technique.
Claims21
In a washer-extractor having a rotary barrel, the improvement comprising an abrasive structure mounted within said barrel for rotation with said barrel, said abrasive structure comprising:
- (1) a structural form having exterior metal surface areas;
- and
- (2) a layer of corrosion resistive material forming an abrasive surface affixed to said exterior metal surface area;
- wherein said material is affixed to said exterior metal surface area by using a molten metal technique forming peaks and valleys.
