<p>A method of continuously wrapping products (3), whereby sheets (5) of wrapping material, as they are fed continuously and together with respective products (3) along a first path (P3), an instantaneous tangent (T) of which extends in a first direction (73) possibly varying from one point to another along the first path (P3), are engaged by respective folding tools (58; 75; 91; 106) fed continuously and cyclically along a second closed path (P4) to perform a folding operation of a respective sheet (5) at each cycle; each tool (58; 75; 91; 106) being imparted, in the course of each folding operation, at least a first movement in a second direction (72) substantially crosswise, at each instant, to the first direction (73), and at least a second movement in the first direction (73). <IMAGE></p> |
