Abstract

Process for manufacturing a sifting device (or strainer baskets) for use in, e.g., in the paper industry for sorting and/or filtering fiber pulp suspensions. Sorter slits may be created between a plurality of substantially parallel rods inserted into respective insets formed in a support element. The rods may be securely held in place by first inserting the rods into the insets and then by permanently bonding the placement of the rods in the support elements with a bonding agent, e.g., as hard-soldering or brazing.
