Description

ABSTRACT:
The invention concerns a procedure for manufacturing a screen-in-lay for systematic-screen fields with square or rectangular frame elements which can be attached to a substructure, on which a correspondingly square or rectangular screen-mat made of a rubber-elastic material, with perforated areas is attached in such a way as to be removable. The screen-mat has boshable, continuous ribs, which can be boshed into corresponding recessions at the upper sides of the flanges of the frame elements. The manufacturing expense for such a screen in-lay is to be reduced by having a section of a flat material cut off for the manufacture of the screen mat, such that only minimal work must still be undertaken on such a section in order to obtain a completed screen mat. For this purpose, at least one longitudinal rib running through until the ends is formed onto the underside of each of the two longitudinal edges of the screen-mat, and strips protruding downwards are attached at the underside of the two transverse sides of the screen mat between the two longitudinal edges, which have bosh ribs downwards which are perpendicular to the longitudinal ribs.
