Abstract
Abstract A process for producing a chemical analytical slide including an upper slide frame, a lower slide frame and a chemical analytical film therebetween. The process comprises passing a strip sheet in a longitudinal direction. printing a bar code on the strop sheet by intaglio printing so that lines of the bar code extend in the longitudinal direction, forming the upper slide frame or lower slide frame from the printed strip sheet and forming the chemical analytical slide from the printed upper slide frame or lower slide frame. In a further aspect, a chemical analytical slide is provided which has a code which extends from one edge of the slide frame to the opposite edge.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
137 words
A process for producing a chemical analytical slide including an upper slide frame, a lower slide frame with at least one of said upper slide frame and lower slide frame having an opening therein and a chemical analytical film therebetween which is exposed through said opening, said process comprising passing a strip sheet in a longitudinal direction, printing a plurality of bar codes on the strip sheet spaced transversely to the longitudinal direction by intaglio printing so that lines of the bar codes extend in the longitudinal direction, forming a plurality of slide frames from the strip sheet so that a bar code is present on the slide frames, and forming the chemical analytical slide wherein at least one of the upper slide frame and lower slide frame is a slide frame formed from the strip sheet.
Claim 2
Dependent Claim
