Abstract

1,196,914. Making screws, shear blades. H. HALMSHAW. 30 Nov., 1967 [1 Sept., 1966], No. 39085/66. Heading B3A and B3W. [Also in Divisions B1 and B2] A screen for sizing particles or separating water from solids is formed by piercing a metal sheet to form rows of parallel slits and bent out portions 10 along one edge of each slit, after which the portions 10 are restored to the plane of the sheet to leave rows of slots narrower than the original slits. A mild or stainless steel sheet 1 is successively pierced to form the slits 12 and louvres 10 by a reciprocating knife blade 4, which is recessed at intervals to form parallel stiffening ribs 13 in the finished screen. The louvred sheet is finally flattened by rolls 15.
