Non-woven covered roller
10316463 · 2019-06-11 · ·

A non-woven covered roller comprising a resin-saturated seamless non-woven tube on a shaft and a process for making the non-woven covered roller comprising non-woven fibers and a shaft surface completely covered with at least the same resin wherein the resin-saturated non-woven tube has a hardness of at least 40 wet Shore A. It also has an outer surface configured to both trap metal debris from a metal web during primary metal fabrication operations and temporarily compress to allow larger metal debris associated with the metal web to pass by without permanently damaging the outer surface of the non-woven covered roller. Furthermore, it has an inner surface sufficiently bonded with the same resin to the outer surface of the shaft to permit satisfactory life of the resin-saturated non-woven covered roller during primary metal fabrication conditions similar to that of conventional shafts that are covered with rubber, urethane, or vinyl, and have not been exposed to the metal debris.

DRY METHODS FOR PRODUCING A NONWOVEN FABRIC FROM TANNED LEATHER WASTE
20240191408 · 2024-06-13 ·

A dry method for manufacturing a non-woven fabric from tanned leather scraps involves providing tanned leather scraps in the form of compact material, subjecting the tanned leather scraps to opening to tear the compact material into fiber, and subjecting the torn material to carding. Textile fibers are added during carding to obtain a web of mixed fibers, the textile fibers including wool fibers. The dry method further involves subjecting the web of mixed fibers to needling to obtain a felt. The web of mixed fibers is free of impregnating agents and includes a leather fiber component composed of tanned leather fibers having a diameter of between 4 ?m and 70 ?m and a length of between 4 mm and 20 mm. The leather fiber component is comprised in a weight percentage greater than or equal to 50% of a total weight of the fibers in the web of mixed fibers.
