In a process of manufacturing screen material a metal matrix is subjected to an electrolytic metal deposition by using an electrolytic bath containing a brightener, the liquid of the bath being forced to flow through apertures in the cathode toward the anode. The metal deposits grow substantially perpendicular to the lands of the matrix and so form a screen having apertures of approximately the same size as the apertures of the original matrix. The screen can be removed from the matrix by previously coating the latter with a separating agent such as beeswax. An installation for performing the process of the invention comprises a perforated cathode as matrix being fixed to cathode fixing means, a perforated anode being fixed to anode fixing means and a pump for providing a forced flow of liquid through the apertures of the cathode toward the anode.
Process of electrolytically manufacturing screen material by depositing a metal upon a sieve-like porous matrix having apertures therethrough, the matrix having a surface from which a screen of deposited metal can be removed, the process comprising, placing the matrix in a electrolytic bath, the bath containing at least one brightener, connecting the matrix as a cathode, spacing an anode from the cathode, flowing the bath liquid at least during part of the electrolytic deposition, through the apertures in the matrix connected as the cathode and only from the cathode toward the anode.
Screen material produced by the process of depositing metal from an electrolytic bath upon a sieve-like matrix using at least one brightener in the electrolytic bath, wherein the screen material is produced by flowing the bath liquid through the apertures in the cathode-connected matrix, only from the cathode toward the anode during at least a part of the electrolytic metal deposition.
