A method and unit (1) for positioning a layer (2) of covering material onto a sheet (3) to be covered, in which an end portion of a strip (8) of covering material is held close to one edge (20) of the sheet (3) before exerting on a surface (41) of the strip (8), opposite that which is brought into contact with the sheet (3), a thrust action such as to curve the strip (8) and progressively bring an end portion (55) of the strip (8) into a position overlying and facing the sheet (3); during the progressive curving the strip (8) is cut transversely to form the covering layer (2) and, with the curving completed, the layer (2) is released and progressively settles onto the sheet (3) to be covered. <IMAGE> |
