Abstract

Improvements in the construction of retention material inlets for paper-making machines and the like, in which the suspension of materials conducted through a plate of holes, with a multitude of channels parallel to each other, extended over the total width of the band to be formed, characterized in that the said channels of the hole plate are widened, in the direction of circulation of the material suspension, in a stepped manner, after an initial section of travel, the transition being made between two successive channel parts with an opening angle of at least 100 degrees.
