    摘要: A wet pulp of mineral fibers or the like is forced between a pulp carrier and a corrugated texturing skid inclined toward the downstream end of a moving slab of the pulp. The corrugations of the skid are co-directional with the machine direction of the conveyor belt that transports the pulp under and beyond the skid.
