The present invention relates to extraction bedplates (10), (110), (210), (310), (410), (510), (610) for use in apparatus (5) for defiberizing paper making stock and methods for making such bedplates. Preferred methods for making such bedplates (10), (110), (210), (310), (410), (510), (610) include the step of cutting a disc shaped blank from a metal plate and the step of forming holes (45), (145), (245), (345), (445), (545), (645), (646) either the metal plate or the disc shaped blank. The holes (45), (145), (245), (345), (445), (545), (645), (646) preferably are formed using a cutting stream, most preferably either a laser or a water jet. Use of a cutting stream to form the holes facilitates the cutting of holes (45), (145), (245), (345), (445), (545), (645), (646) having non-circular, and preferably tesselatory, cross sections as well as holes (45), (145), (245), (345), (445), (545), (645), (646) extending at acute angles with respect to an axis (20) of the bedplate.

L'invention concerne des plaques support (10), (110), (210), (310), (410), (510), (610) d'extraction utilisées dans un appareil destiné à défibrer une suspension de pâte à papier, ainsi que des procédés de fabrication de telles plaques support. Les procédés préférés de fabrication de ces plaques support (10), (110), (210), (310), (410), (510), (610) consistent à découper une ébauche circulaire dans une plaque métallique et à créer des trous (45), (145), (245), (345), (445), (545), (645), (646) dans la plaque métallique ou l'ébauche circulaire. De préférence, ces trous (45), (145), (245), (345), (445), (545), (645), (646) sont réalisés au moyen d'un courant de coupe, mieux encore au laser ou au jet d'eau. L'utilisation d'un tel courant pour réaliser des trous facilite la découpe de trous (45), (145), (245), (345), (445), (545), (645), (646) dont les sections transversales sont non circulaires et, de préférence tessélées, ainsi que de trous (45), (145), (245), (345), (445), (545), (645), (646) s'étendant à angles aigus par rapport à un axe (20) de la plaque support.
