摘要： A screening body for a pulp digester includes two, spaced apart ring supporting a plurality of axially extending screening bars each of which has a foot portion frictionally received in and welded to a correspondingly formed recess formed on the inner side of each of the ring segments; an apparatus for manufacturing a screening body is also provided and which includes a first assembly member which mounts a form for receiving the ring member segments in parallel relation and into which are inserted the screening bars with the foot portions fractionally received in complementary recesses formed on the inner side of each of the ring segments; a retaining member in the form of a second assembly device includes a cylindrical drum surface which is pressed against the screening bars of a partially assembled screening body section while a second and subsequent sections of the screening body are assembled.

摘要： The present invention relates to a straining device in association with the displacement of liquid through a pulp bed preferably in connection with the withdrawal of cooking liquid in a continuous digester (1) for producing chemical pulp, which straining device (2) is preferably rectangular and comprises a number of strainer-bars (3), arranged in parallel, which have been fixed to at least two rod elements (4, 5), which are placed transversely in relation to the lengthwise extension of the bar-strainers, the said rod elements (4, 5) being made of metal, preferably stainless steel, and having a strength value RP 0.2 at 100.degree. C. which exceeds 200 MPA, preferably 300 MPA, and more preferably 350 MPA, and the width of the said rod element (4) being less than 800 mm, preferably 650 mm, and more preferably 550 mm, so that the straining device becomes self-supporting.
