A method of continuously wrapping products, whereby sheets of wrapping material, as they are fed continuously and together with respective products along a first path, an instantaneous tangent of which extends in a first direction possibly varying from one point to another along the first path, are engaged by respective folding tools fed continuously and cyclically along a second closed path to perform a folding operation of a respective sheet at each cycle; each tool being imparted, in the course of each folding operation, at least a first movement in a second direction substantially crosswise, at each instant, to the first direction, and at least a second movement in the first direction.
