<p>A method and machine (1) for wrapping an elongated, substantially parallelepiped product (2) having two opposite longitudinal end bases (8), whereby the bases (8) of the product (2) are engaged by a conveyor head (6) fed continuously by a conveyor (7) along a wrapping path (P1), along a first portion of which a sheet (3) of wrapping material is folded into a U about the product (2), and along a second portion of which the sheet (3) of wrapping material is further folded and stabilized to form a tubular wrapping (10); the conveyor head (6) being moved with respect to the conveyor (7) to cause the sheet (3) of wrapping material to cooperate, along the second portion of the wrapping path (P1), with at least one passive fixture (58,61) operating on the sheet (3) to form the tubular wrapping (10). <IMAGE></p> |
