Zusammenfassung
(EN)

A paper pulp screening apparatus wherein a modular cylindrically-shaped screen plate is formed of a thin material of uniform thickness bent to form an undulating shape to increase the screening area, and the screen plate is supported by cylindrical-backing members to give the plate strength, with the plate being formed into various complex shapes. Manufacturing methods for forming the undulating shapes are disclosed.
