Abstract (en)
[origin: US4568185A] A measuring table for facilitating the accurate densitometric measurement of a measuring field strip on a paper sheet is disclosed. The table carries a removable hold-down plate that is positioned between side stop rails and a registering rail. The hold-down plate is held in place on the table by cooperating electromagnets and ferromagnetic metal disks and holds a sheet of paper in place between the plate and the table's surface. The hold-down plate also includes a measuring slot so that a densitometer positioned on the upper surface of the plate is afforded optical access to the measuring field strip imprinted on the paper sheet.

Auf einem Meßtisch zur densitometrischen Auswertung von bedruckten Bogen ist eine abnehmbare Niederhalteplatte für den Bogen angeordnet. Auf der Niederhalteplatte stützt sich während des Meßvorgangs ein wanderndes Densitometer ab. Die Niederhalteplatte weist einen Meßschlitz auf. Mittels Magneten wird die Niederhalteplatte gegen die Meßtischoberfläche gezogen.
