ABSTRACT:
The invention relates to a process and tooling for the lining of molds for curved pieces, the process comprising the application of a lining (15) of width A2on the mold (3) in several successive passes, exerting pressure thereon so that it adapts to the curvature of the piece, and the number of passes being the minimum required so that the width A2of the tape (15) allows achieving such adaptation, and the tooling comprising a drum (25) for applying the lining (15), a means of attaching its end to the mold (3) at the beginning of each pass, a conical roller (25), to exert pressure on the lining (15) uniformly along its entire width, and means (26, 29) for its movement through side guides (27, 28) arranged on the mold (3) parallel to the curved lines (5, 7) demarcating the piece.
