ARC Merino Wool Rotos 7, 14, 20cm

Merino wool is a highly flexible material with an incredibly fine pile of approximately 18 microns in diameter. It has a high absorption and covering capacity and is ideal for the use on micro-rough and micro-scratched surfaces as the ski-base. Therefore, the merino wool roller is particularly suitable for applying waxes and liquid polymers considering that rubbing on the insole also generates heat, facilitating application. 3 rolling cycles are carried out from tip to tail of the ski-base at a drill speed of about 1500 rpm by pressing the roller on it to facilitate the spread of the gliding products.
In World Cup, one roller is used for each different product. Furthermore the merino wool roller, used at high rotation speed (1500/2000 rpm) without pressing on the base, is particularly suitable for the final polishing of any wax or polymeric accelerator, both solid and liquid, after polishing with the soft nylon or the soft horsehair brush. Also in this case it’s necessary to carry out 3 rolling cycles from tip to tail of the base. The micrometric hairs polish in depth where wires or hairs of the other brushes cannot reach. A different roller from the one used for the application must be used for polishing.
