ABSTRACT:
A former for cylinder mold, paper making, machines, of the type now known as B.R.D.A., and having a pressure lid, an explosion chamber with a central imperforate baffle, and a manifold feeding stock to the chamber is characterized by the flow box unitarily containing an explosion chamber separated from a tapered manifold by an apertured plate. Stock is directed from the plate apertures in a direction normal to the baffle for improved mixing. The pressure lid includes a forward cantilevered tip end with a predetermined tip clearance, and is unusually elongated to increase drainage effect. The lower plate of the slice is rubber with an inner bulb and it is slidable axially outward for replacement. The curvature and clearances of the lid are changeable during operation and the lid acts as an adjustable gate for controlling pooling under the lid.
