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.
