It is well known that a fine relief pattern (a surface structure) in the ski base gives a good glide especially noticeably in warm snow conditions. However knowledge is lacking about advantages gained by surface structuring the ski's running groove. Also tools for this particular purpose are missing. From our tests on cross-country skis it seems as if the glide can be improved by also surface structuring the running groove. The invention is a, for this purpose adapted, roller with relief pattern in the mantle surface, which can be part of tools or machines for impressing or grinding the ski base in the running groove. |
