ABSTRACT:
The apparatus contains a measuring comb for the material to be tested. The plate like projections of the comb define measuring gaps of different widths through which the material passes to be tested for determining characteristic magnitudes associated with that material. The measuring comb is adjustable transversely to the direction of movement of the test sample and each measuring gap is adjustable to a nominal position. Consequently, the test sample passes through each measuring gap under the same geometrical conditions and is not subjected to deflections which vary from one measuring gap to another. A device for temporarily removing the test sample from the measuring gap, and subsequently guiding it back into the gap, is arranged in the region of the measuring comb so that the zero setting of the apparatus may be adjusted. This not only relieves the operator of the task of manually removing the test material from the measuring gap but also ensures that the test material will subsequently be returned to the correct measuring gap.
