Abstract
Yarn tensile textile apparatus contains drawing-off means (11) for continuously drawing-off the test material (G) from a supply, two roller pairs (W, W') at a distance from one another for elongating the test material (G), and a store (12) arranged between the drawing-off means (11) and the first roller pair (W). Each roller pair (W, W') contains a transport roller and a pressing roller (4, 5; 4', 5') arranged so that a periodically opening and closing clamping gap for the test material (G) is formed between the rollers of each roller pair. Each transport roller (4, 4') includes a first circumferential part for bearing against its pressing roller (5, 5') and a second circumferential part at a distance from its pressing roller (5, 5'). The apparatus permits tensile testing according to the principle of constant rate of deformation, and the apparatus is insensitive to soiling and can be used for testing a variety of test materials.
