Abstract:
1. A method for producing a fiber bale comprising the steps of: providing a bale press comprising an upper convex bale platen and a lower convex bale platen, each of the convex bale platens includes a convex surface, the convex surface having a high point and a base, a distance between the high point and the base is about 1 cm to about 10 cm; filling said press with a fibrous material; pressing said fibrous material via said press by exerting a total pressure in a range of about 70 psi to about 700 psi on said fibrous material for about 1 second to about several minutes; thereby producing a highly compressed fibrous material; retracting at least one of said bale platens thereby allowing said highly compressed fibrous material to expand about 0 to 25 percent by height; packaging said expanded highly compressed fibrous material with a wrapping material; securing said wrapping material, thereby producing a highly compressed hexahedral fibrous material substantially free of disrupting curvatures on a top side or a bottom side, wherein a crown height of said highly compressed hexahedral fibrous material being at least 50 percent less than a crown height of a bale pressed by standard flat platens after a period of 48 hours out of said press.
