Abstract: A stacking device for sheet products, comprising at least one wheel associated with rotary actuation means that has at least one plurality of tangential peripheral receptacles for accommodating already-folded products fed by a conveyor to at least one pick-up station, at least one first product deposition station, provided with a first fixed stop element for engaging the products accommodated in the receptacles and with a first movable supporting surface for picking up a first stack of products extracted from the receptacles, and at least one second product deposition station, which is provided with a second upper stop element and a second lower stop element, movable in opposition and both suitable to engage products accommodated in the receptacles, and with a second movable supporting surface suitable to pick up a second stack of products extracted from the receptacles.

Abstract: A cutting and folding assembly for sheet products of the multiple-ply type, comprising at least one rotatably supported first roller with cutting blades for cutting the continuous ribbon substantially transversely, associated with a rotary actuation; at least one rotatably supported second roller, associated with a rotary actuation, the second roller provided with a first retention suction for the products cut; and at least one third rotatably supported folding roller, that has a rotary actuation and a second retention suction for cut products, the first, second and third rollers having parallel axes and being in contact along respective generatrices, the second roller being provided with a pressure generation element for generating pressure on the back of the products to keep their plies in contact with the third roller during the formation of the transverse fold.

Abstract: A transfer device for sheet products, comprising at least one drum which rotates about its own axis and is provided with retention apparatus adapted to retain the products so that they adhere to its outer surface along at least one portion of its rotation, and at least one star conveyor which is provided peripherally with a plurality of receptacles for the insertion of the products and for the release of the products at subsequent production stations. At least one element for rotationally entraining the products one by one, is further provided which is arranged substantially between the drum and the star conveyor and is adapted to follow the insertion of each of the products within the receptacles.

Abstract: An apparatus for folding ribbons tidily, particularly ribbons fed from a reel, comprising at least one support for supporting at least one first folding assembly and one second folding assembly on a main footing, and selective positioning pivots for arranging the folding assemblies with respect to the footing in respective mutually exclusive operating configurations, so as to allow the preset tidy folding of at least one ribbon according to the required processing needs.

Abstract: A logo embossing assembly for sheet products comprising at least one supporting frame for at least one embossing roller and at least one presser roller, which are arranged so as to have parallel axes substantially in mutual contact along respective generatrices and between which at least one continuous ribbon from which the sheet products are obtained can pass, the embossing roller and the presser roller being provided with respective motion transmission elements which are associated with a power-assisted rotary actuation, that is functionally controlled by at least one programmable control and processing unit adapted to perform the angular phase adjustments of the embossing roller with respect to fixed references of the continuous ribbon, so as to provide figures in relief on the products in predefined regions in relation to specific production requirements.
