The invention is based on the requirement to design such a sample feeding device in such a way that it enables the storage of a larger number of samples and the automatic, step-by-step supply to the automatically operated clamping hoppers of the tearing machine as well as the automatic removal of the upper sample after the break . of the sample 'and thus an intervention by the test technician.

According to the invention, several samples are provided by plate-like samples: on his mand there are several more identical samples: arranged; Get the elements for one each: sample:: atWeISt ₃ against another Mt Pr'öbm \ bestüctiien _; Frägen from * WBChselbar and after clamping a sample 'smoothly absent Mr is * As another: Medium: zwr: Solution: the: Mrftnämgsmfgäbe: HAT the prol3emufimru ^ g: seiriricMimg erfindmgsgemaß: unifying sample carrier automatically such ■ -schrittweise twisting:; ; ;
