发明名称 FABRICATION OF WIRE GAUZE FOR MAKING OF WATER MARKS, WIRE GAUZE FOR MAKING OF WATER MARKS, APPARATUS FOR ITS FABRICATION AND DOCUMENT PROTECTED AGAINST COUNTERFEIT
摘要 FIELD: process engineering.SUBSTANCE: invention relates to the fabrication of a wire gauze for the formation of water marks. Proposed process comprises the steps that follow. Stable bonding of at least one electroplate element with a preset first working side of the wire gauze for the water marks formation. Plastic deformation of at least one preset section of the said wire gauze for the water marks formation. This section comprises at least partly the said at least one electroplate element and extends relative to the wire gauze plane. The plastic deformation step comprises mutual convergence between a male die to be coupled by its model surface with the first working side zone and at least one female die to fit in an appropriate thrust zone by its contrast surface. The said thrust zone is located on the second side of the said wire gauze arranged opposite the said first working side. Note here that the said model surface has at least one recess shaped to mate with the said electroplate connected to the said first working side. The said one recess is located in the zone of the said model surface to face the said one electroplate element applied on the said first working side of the wire gauze.EFFECT: perfected method.16 cl, 10 dwg
