GH-3 COURTAULDS TETRAPOD WALKER

The Tetrapod tester tests the mechanical action on surface texture of textile carpet.
A cylindrical drum, lined with specimens and containing the tetrapod, is rotated the required number of times so that the tetrapod ‘walks’ over the specimens.
The appearance of the tested specimen is compared to that of a concurrently tested controlled specimen
