An apparatus for wrapping products, in particular stacks of overlapped sheets of paper, such as stacks of napkins, tissue papers, or similar products, said apparatus comprising: - a feeding station configured to feed a plurality of products to be wrapped along a first predetermined feeding direction, and a plurality of wrapping sheets along a second predetermined feeding direction, said first and second predetermined feeding directions (11,12) being parallel to each other at least for a predetermined portion; - a pushing station configured to selectively push each product of said plurality from said first feeding direction towards said respective wrapping sheet, at said predetermined portion, along a direction substantially orthogonal to said first and second feeding directions (11,12), in such a way to cause said respective wrapping sheet to be wrapped around said product to be wrapped leaving free end portions, said pushing station being, furthermore, configured to cause said product to move on a support surface of a respective support element that is movably mounted along a predetermined advancing direction parallel to said first and second feeding directions (11,12); - a displacement device configured to move said plurality of support elements along said predetermined advancing direction; - a first folding station configured to fold at a first side of said product the free end portions of said wrapping sheet wrapped around said product; - a first welding station configured to weld said folded end portions at said first side of said product; - at least a second folding station configured to fold the end portions of said wrapping sheet at a second side of said product and of a third side opposite to said second side; - at least a second welding station configured to weld said folded end portions of said wrapping sheet at said second and third sides (102, 103) of said product in order to complete the wrapping; - a discharge station configured to discharge said wrapped products; said apparatus being characterised in that between said first welding station and said second folding station a rotation station is provided configured to cause each support element to rotate to position said support element and, therefore, the respective wrapped product positioned on the respective support surface, from a first spatial orientation to a second spatial orientation orthogonal to the first one, and in that after said rotation, said displacement device is arranged to move said rotated wrapped product along a second advancing direction parallel to, or coincident with, said advancing direction. - a feeding station configured to feed a plurality of products to be wrapped along a first predetermined feeding direction, and a plurality of wrapping sheets along a second predetermined feeding direction, said first and second predetermined feeding directions (11,12) being parallel to each other at least for a predetermined portion; - a pushing station configured to selectively push each product of said plurality from said first feeding direction towards said respective wrapping sheet, at said predetermined portion, along a direction substantially orthogonal to said first and second feeding directions (11,12), in such a way to cause said respective wrapping sheet to be wrapped around said product to be wrapped leaving free end portions, said pushing station being, furthermore, configured to cause said product to move on a support surface of a respective support element that is movably mounted along a predetermined advancing direction parallel to said first and second feeding directions (11,12); - a displacement device configured to move said plurality of support elements along said predetermined advancing direction; - a first folding station configured to fold at a first side of said product the free end portions of said wrapping sheet wrapped around said product; - a first welding station configured to weld said folded end portions at said first side of said product; - at least a second folding station configured to fold the end portions of said wrapping sheet at a second side of said product and of a third side opposite to said second side; - at least a second welding station configured to weld said folded end portions of said wrapping sheet at said second and third sides (102, 103) of said product in order to complete the wrapping; - a discharge station configured to discharge said wrapped products;
