ABSTRACT:
A tough, flexible, sheet-like matrix for a bas-relief pattern is made by casting a reinforced resin on a mold of the pattern and submerging a perforated plate in the liquid resin so that the plate is parallel to a substantially flat plane generated by the lowest points of the pattern. The matrix, exclusive of the peaks and valleys of the pattern, has a uniform thickness and has a multitude of studs integral with and dependent from the sheet. A porous matrix is useful for the wet-end texturing of fiberboard at the final suction press roll of a Fourdrinier fiberboard machine.
