Abstract:
A method and a security sheet inspection apparatus is described of the type comprising at least a main driving cylinder (3), whereto a security sheet to be inspected is made to adhere, as well as an inspection system comprising at least an illuminator (5), a camera (6) for sheet image acquisition and a processing unit of said image to check sheet print quality, wherein there is further provided a sheet-feeder (2) feeding sheets from a tray (1) above the main cylinder (3) and a pair of secondary cylinders (8’, 8’’), mutually adjacent and adjacent to said main cylinder (3), to draw each security sheet from the main cylinder, to upturn it and present it again turned face down on said main cylinder (3), the three cylinders being apt to rotate and being controllable independently from one another, the cylinders and the inspection system being housed in a self-enclosed unit.
Abstract:
An inspecting system for security supports is disclosed, wherein a rotating cylinder provided with transparent sectors is apt to transport said support past an image acquiring device, and in which a transparency inspecting device is placed partially inside and partially outside the cylinder so that the electromagnetic inspecting beam is intercepted by said supports held lying onto said transparent sectors. Further, the inspecting system is provided with shading means, in the optical pattern, apt to define a cone of shade only in correspondence of sensitive elements of a camera.
Abstract:
An apparatus (1) for acquiring multispectral images of one side of a printed sheet (3) comprising a supporting surface (2) adapted to allow the placement of a sheet (3) whose printed image is to be acquired, a suction cylinder (6) adapted to make it possible to aspirate and lay without contact the sheet (3) that is made to pass thereon, grip means (4) adapted to make it possible to capture and immobilize one end of the sheet (3) without making contact with the image to be acquired, and a multispectral image acquisition system (5) arranged above the cylinder (6).
