UN IMPIANTO DI LAVORAZIONE DELLA SUPERFICIE DI SCIVOLAMENTO DI UNO SCI

摘要

A working plant of the sliding surface ( S ) of a ski ( C ) comprising: a rotating grinding wheel ( 2 ) whose operating surface ( 3 ) has a plurality of projections and depressions to make the grooves for water drainage from the sliding surface of the ski; a tool ( 4 ) configured to be in contact with the operating surface ( 3 ) of the grinding wheel ( 2 ) and make the projections and depressions thereon; a movement unit ( 5 ) of the tool ( 4 ) to manoeuvre it on the operating surface ( 3 ) of the grinding wheel ( 2 ); a logic control unit ( 8 ) operatively connected to the movement unit ( 5 ) and programmed to vary the processing depth of the tool ( 4 ) on the operating surface ( 3 ) of the grinding wheel ( 2 ) as a function of the rotation angle of the grinding wheel ( 2 ). The plant ( 1 ) further comprises data entry means ( 15 ) in the logic control unit ( 8 ) configured to insert graphic elements, drawings or the like to be reproduced on the sliding surface ( S ) of the ski ( C ) by means of the grinding wheel ( 2 ), the logic unit ( 8 ) controlling the movement unit ( 5 ) so as to vary also the distance along the longitudinal development axis of the grinding wheel ( 2 ) between the projections so that said projections have variable-pitch helical trajectories.
