Packaging machine with sealing device for paper wrapping materials

Packaging machine for packaging tissue paper products by wrapping a paper wrapping sheet around the products, the machine comprising:

• a product feeding station for grouping and feeding, one by one in succession, groups of products comprising at least one product,
• a wrapping station for wrapping paper wrapping sheets around the groups of products,
• downstream of the wrapping station, a sealing station for sealing the paper wrapping sheets wrapped around the groups of products,
• wherein the sealing station comprises a channel for moving forward the groups of products and a pair of sealing members provided opposite each other on two sides of said channel, each sealing member of the pair of sealing members having a uniform sealing surface made of a material in which eddy currents can be induced when the material is subjected to a change in magnetic field, said each sealing member comprising at least one flexible element driven between at least two return members, the sealing members being respectively associated with an electromagnetic induction device adapted to induce eddy currents in said material, wherein both sealing members are formed by at least one uniform tape of the material in which eddy currents can be induced, defining the uniform sealing surface.
