Abstract In screening apparatus for paper making stock incorporating a cylindrical screen member provided with screening perforations which are circular in section, the screen member is provided with multiple bars extending generally axially thereof in circumferentially spaced relation along the inlet side thereof to define with the adjacent surface of the screen member a series of pockets. The radial dimension of these bars is such that the bars occupy a sufficient portion of the distance between the screen member and the rotating vanes in the supply chamber of the screen to interrupt the circulation of the stock adjacent the inlet side of the screen member and thereby to develop turbulence in the stock within each pocket. Test results have established that this construction and mode of operation result in significant increase in the capacity of the screen in terms of the tonnage per day of accepted stock and also in the avoidance of fractionation of the stock on the basis of fiber length.
