The tensile test is an important test for detecting the mechanical property of the rubber material used by the tire, and the tensile test can detect the tensile strength, elongation, stress at definite elongation, tensile stress at yield point, breaking strength and the like of the rubber material, so that the tensile test is an indispensable test for evaluating rubber material parts used for manufacturing the tire. In the case of a tensile tester, a contact extensometer and a video extensometer are generally used to measure the tensile length of a web. Because the video extensometer does not contact the sample, not only can the high temperature tensile test be carried out, but also the test result is higher than the precision of the contact extensometer.

When a video extensometer is used for a tensile test, a cutter is required to punch a sample rubber sheet with a certain shape, and then a plastic plate with a round hole at a certain distance is used for coating and drawing two mark points at a certain distance. Because the selection of the cutting knife is different usually due to different tensile tests, manual marking after cutting is adopted mostly. The mode of firstly punching and then manually coating the rubber sheet marking points is not only low in efficiency, but also certain errors often exist in the size and distance of the coated points, the test result and the precision are affected, and therefore the marking device which is low in cost and can adapt to various types of cutting knives is needed.

Accordingly, further developments and improvements are still needed in the art.
