Abstract
Screen panels are disclosed which are adapted to form a portion of a screening cylinder for screening fibrous material. The screen panels are unitary and made of wear-resistant material including a plurality of axially extending grooves on the outer surface of the screen panel, a plurality of slit-shaped screening orifices disposed at the bottom of the axial grooves, at least one support ring extending circumferentially across the surface of the screen panel and integral therewith, and a flange is formed at the sides of the screen panel so that the screen panels can be assembled together without the use of welding.
