Abstract:
A method for continuously wrapping products, comprising stages for the continuous feed along a given path, an instantaneous tangent of which extends in a first direction, varying from point to point on the path, of a succession of products to be wrapped, together with respective sheets of wrapping material, the latter being at least partially folded around the respective products to define an intermediate wrapper having at least one flap substantially parallel with the plane in which said path lies and projecting in such a way that it is offset from a surface of the product; folding of the flap by at least one folding tool, extending along a respective axis and cooperating with the flap during the continuous feed of the intermediate wrapper and relative product along an intermediate folding portion of the path; the folding tool moving forward in a continuous, cyclical fashion along a closed path and moving with a law of motion which derives from the combination of at least two distinct movements, one being a movement in a second direction parallel with its own longitudinal axis and transversal to the plane in which the flap lies; the other movement being in the first direction of the path, following the continuous feed of the intermediate wrapper and relative product along the intermediate folding portion, and allowing the flap to be brought into contact with the surface of the product.
