ABSTRACT:
An improved cross direction fiber movement and dewatering device for typical papermaking machinery comprised of a main body (22) typically made of ultra-high molecular weight polyethylene conventionally machined with vacuum orientation diagonal slots (30) with alternating flat support zones on the top of the unit, equal in relation to the machined vacuum slots (31). The device promotes fiber reorientation on x and y axis, or cross direction to the general flow patterns of the paper machine while dewatering the pulp slurry (20) and promoting improved paper qualities.
