Description

Albert Hertzi Marie Anna Räder geb. Heeleruann, Gotthelf Hermann Kurt Röder und Arthur Hermann Röder in Elsterwerda. Bei Lichtpausmaschinen verwendet man sehr häufig Transportbänder, die das Negativ und das Kopiergut. gegen eine Glasscheibe anpressen. Um jedes Schräglaufen des Bandes zu vermeiden und einen gleichmäßigen Preßdruck über die ganze Fläche zu gewährleisten, soll das Band nach der Erfindung aus zwei miteinander verklebten Lagen eines gummierten Stoffes -bestehen, die an den Rändern durch längslaufende und auf der Fläche durch querlaufende Stahlbänder verstärkt sind.Albert Hertzi Marie Annaräder née Heeleruann, Gotthelf Hermann Kurt Röder and Arthur Hermann Röder in Elsterwerda. Used on blueprint machines one very often conveyor belts that hold the negative and the copy. against a pane of glass press on. In order to avoid any skewing of the belt and an even To ensure pressure over the entire surface, the tape according to the invention consist of two layers of rubberized material glued together, which are attached to the edges by longitudinal and on the surface by transverse steel strips are reinforced.
