Cutting and folding assembly for products such as tissues, napkins and the like

A cutting and folding assembly for sheet products of a multiple-ply type, formed starting from at least one continuous ribbon, comprising:

• at least one first roller, which is rotatably supported for rotation about an axis thereof by fixed parts of a production line;
• rotary actuation means connected to said at least one first roller;
• a plurality of blades, provided along an outer surface of said at least one first roller, for cutting a continuous ribbon substantially transversely;
• at least one second roller, which is rotatably supported for rotation about an axis thereof that is parallel to the axis of said at least one first roller by the fixed parts of the production line;
• rotary actuation means connected to said at least one second roller, said at least one second roller having an outer surface and being in contact with said at least one first roller along a generatrix;
• first retention means provided on the outer surface of the at least one second roller for retaining by suction the sheet products cut by said at least one first roller;
• and at least one third folding roller, which is rotatably supported, for rotation about an axis thereof which is parallel to the axes of said at least one first and second rollers, by the fixed parts of the production line;
• rotary actuation means connected to said at least one third folding roller, for rotation thereof substantially in contact with said at least one second roller along a generatrix, said at least one third roller having an outer surface, with second retention means provided thereon for retaining the cut products by suction;
• at least one fixed abutment, located proximate to said at least one second roller and which is adapted to provide at least one transverse fold in each of the cut products;
• and pressure generation means provided at said at least one second roller for generating pressure on a back part of each of said sheet products so as to keep plies thereof in contact with said at least one third roller during the formation of the transverse fold.
