Abstract: A method of producing a wallet packet with a hinged lid, whereby a blank, having a first portion defining a body and a second portion defining a hinged lid of a relative wallet packet, is fed into a respective pocket, having a respective pair of side by side seats, of a packing wheel, so that the relative first portion defines two adjacent receptacles separated by a central rib; and wherein the pocket is fed through a loading station, where the two receptacles simultaneously receive respective wrapped groups of cigarettes; one of the two receptacles then being turned over onto the other to define the body of the relative wallet packet.

Abstract: A method of packing pairs of wrapped groups of cigarettes in wallet packets with a hinged lid, whereby a blank—having a first portion defining a body, and a second portion defining a hinged lid of a relative wallet packet—is fed into a respective pocket—having a respective pair of adjacent seats—of a packing wheel to define, with the relative first portion, two adjacent receptacles separated from each other by a central rib; the two receptacles are fed through a loading station to successively receive respective wrapped groups of cigarettes having respective collars, and one receptacle is then turned over onto the other to define the body of the relative wallet packet.

Abstract: A rigid package of tobacco articles, having a container, in turn having an open top end closed by a hinged lid, and a collar fixed to the inside of the container to project partly outwards of the open top end; the container is substantially parallelepiped-shaped, and has two end walls, and a lateral surface which is bounded by the end walls and has two, respectively front and rear, minor lateral walls, and two major lateral walls; a hinge of the lid is located on the front minor lateral wall; the container is formed by folding a flat blank substantially in the form of an elongated rectangle; and the collar is formed by joining two separate portions, at least one of which is joined to the blank along a respective preformed fold line.

Abstract: A rigid cigarette packet having a case (1) defined by a cup-shaped container (12) closed by a hinged, lateral-opening lid (11), and wherein the lid (11) incorporates at least part of a top wall (4) of the case (1); and the case (1) is formed from a blank (44) having two panels (4?, 4?) which are superimposed to form the top wall (4) of the case (1), and houses a tubular collar (18) closed at the top by a wall (20; 67; 74) adjacent to the top wall (4) of the case (1) and including a removable panel (27; 71; 80) located at the lid (18).

Abstract: A method and unit for handling and processing blanks for packing tobacco articles, wherein the blanks, arranged in groups located in a storage area in a given original arrangement, are removed in groups from the storage area and fed along a path extending through a work station where each blank is subjected to at least one processing operation; the blanks are again formed into groups, and are removed in groups from the path, downstream from the work station, to be fed back to the storage area, and to be formed, in the storage area, into a given arrangement normally similar to the original arrangement; the groups are arranged, in the given arrangement, on pallets located in the storage area, which comprises an unloading area located at an input end of the path, and a loading area located at an output end of the path; a first pallet, loaded with groups of blanks for processing, is moved into the unloading area to feed the groups along the path, and an initially empty second pallet is moved into the loading area

Abstract: To pack a group of cigarettes in a rigid packet, a collar, a respective inner sheet of wrapping material and a respective group of cigarettes are fed successively into a same conveying seat in which the collar and the inner sheet are at least partly folded together about the group of cigarettes as of respective flat initial configurations.

Abstract: A method for wrapping an elongated, substantially parallelepiped product (2) having two opposite longitudinal end bases (8), by engaging the bases (8) of the product (2) by a conveyor head (6) fed continuously by a conveyor (7) along a wrapping path (P1) and folding a sheet (3) of wrapping material into a U about the product (2) along a first portion of the wrapping path and further folding the material along a second portion of the wrapping path to stabilize the fold and form a tubular wrapping (10). The conveyor comprises a wheel (17) and a plurality of conveyor heads on the wheel, each head being movable with respect to the wheel (17) to cause the sheet (3) of wrapping material to cooperate, along the second portion of the wrapping path (P1), with at least one passive fixture (58, 61) operating on the sheet (3) to form the tubular wrapping (10).

Abstract: A method and machine for wrapping a product in a sheet of heat-seal wrapping material, whereby the sheet of wrapping material is folded onto the product so that one portion of the sheet of wrapping material is at least partly superimposed on at least another portion of the sheet of wrapping material; a sealing surface of a sealing head is brought into contact with the superimposed portions at a given lead-in temperature, and is maintained contacting the superimposed portions for a given time interval during which the temperature of the sealing surface is gradually increased to a given working value, and is once more restored to the lead-in value once the sheet of wrapping material is released.

Abstract: A method and machine for wrapping a product in a sheet of heat-seal wrapping material, whereby the sheet of wrapping material is folded by a fixed folding device onto a wall of the product so as to superimpose at least two portions of the sheet of wrapping material; the sheet of wrapping material, once folded, is gradually released from the fixed folding device; and a sealing surface of a sealing head is brought gradually into a position facing the superimposed portions as the superimposed portions are gradually released from the folding device.

Abstract: A method and machine for wrapping products in respective sheets of heat-seal material, whereby the products are fed successively along a first wrapping path to form, about each product, a tubular wrapping having two opposite open ends, and are then fed successively along a second wrapping path to close and seal the respective open ends; the products being fed with a first spacing along the first wrapping path, and with a second spacing, smaller than the first spacing, along the second wrapping path.

Abstract: A method for gumming sheet material, whereby a sheet is fed along a path directly facing a free surface of a bath of gum, and an electric field is generated over a portion of the sheet to draw the gum onto the portion.

Abstract: A method and device for feeding sheet material, whereby the sheet material is fed in a given traveling direction along one face of a plate by a fluid bed movable along the face in the traveling direction; the fluid bed being formed by at least one jet of fluid, which is directed in a direction substantially tangent to the face and concordant with the traveling direction, and is fed inside a window formed through the plate.
