Process for producing a board for gliding over snow, reinforcement, and board for gliding over snow comprising such a reinforcement

The present invention relates to a process for producing a board for gliding over snow, which comprises an internal rigid reinforcement. Board for gliding over snow () comprising a gliding sole plate () bordered by metal side edges (), an upper protective and decorative layer (), and a filler core (), including, on at least one of its faces, the lower face and/or the upper face, at least one internal rigid reinforcement (), wherein this internal rigid reinforcement has at least one laterally flush zone () in the region of the heel of the board for gliding over snow so as to allow the centering of the median longitudinal axis of said reinforcement relative to the median longitudinal axis of the board for gliding over snow.
