Abstract: In a spray gumming unit, a gumming device is equipped with an ejector that sprays an adhesive substance and that is connected with a shutter element. The shutter element moves towards and away from the ejector between a position where it closes the ejector and in which a pad, fixed to one end of it, is in contact with the ejector, and a position where the ejector is left open. During the movement of the shutter element and of the pad between the ejector open and closed positions, an applicator applies an antiadhesive liquid substance on the pad.

Abstract: A rigid package with hinged lid which holds a group of cigarette packs stacked flat against one another, parallel with the bottom of the package, along a stacking axis which is at a right angle to the longitudinal axes of the packs comprises a container and a lid, which are hinged together, and an inner frame which is partially inside the container; the package is made from a flat blank which is substantially rectangular and, in the direction of its longer longitudinal axis has a main portion designed to define the container and the lid, and a longitudinal end appendix designed to be folded over the main portion to define the inner frame; the appendix is substantially U-shaped and is hinged, with its arms, to two side panels of the blank which define the sides of the package and surrounds a longitudinal free end of the main portion; the free end consists of a panel designed to define the bottom of the package, and two side tabs and a longitudinal end tab defining respective flaps for closing the bottom; the g

Abstract: A rigid wrapper for tobacco products comprises a cupped container and a similarly cupped lid hinged together along respective rear edges, also a reinforcing frame located partly inside the container and fixed to a front face and to two flank faces of the container. The wrapper is fashioned from a substantially rectangular diecut blank with a predominating longitudinal axis, which incorporates a main portion providing the container and the lid and a longitudinal appendage providing the frame; the appendage is essentially U-shaped, hinged by two arms to two lateral panels of the blank providing respective flanks of the wrapper, and circumscribes a free longitudinally-extended extremity of the main portion shaped and creased to include a panel providing a bottom of the wrapper, also two side flaps and a longitudinal end flap functioning as bottom end folds.

Abstract: A packet for long articles comprises a first inner wrap around a group of articles and a second outer wrap around the first wrap which, together with the inner frame, envisaged when the packet is of the rigid type with hinged lid, constitute specific packaging components of the packet. The packet is equipped with a length of magnetic strip for data storage which is applied directly to a specified part of at least one of the specific packaging components in a hidden position not visible from the outside of the packet. If the packet has a revenue stamp or an insert, constituting additional components, the length of magnetic strip may be applied to at least one of said additional components, again in a hidden position.

Abstract: Adhesive material is directed by two gumming applicators onto selected portions of a wrapping material as it advances in a given feed direction at a predetermined velocity, with no interruption in the movement of the wrapping material. The two applicators make a forward pass and a return pass, each composed of two constituent passes, during the course of which the adhesive material is deposited simultaneously along respective first and second segments of a first trail in the forward direction and in like manner along respective first and second segments of a second trail in the reverse direction; each complete trail extends transversely and substantially across the full width of the wrapping material.

Abstract: A method of overwrapping packets of cigarettes is implemented utilizing a machine by which packets and respective sheets of wrapping material are fed singly and in timed succession to a folding station where each packet is directed against a central portion of the corresponding sheet and advanced together with the sheet through a tubular duct of proportions such that the sheet is constrained to fold into a U formation around the packet. To optimize the folding action, the duct is fashioned with two longer side walls of convex profile by which the two lateral portions of the sheet flattened over the main lateral faces of the respective packet are engaged and compressed only along a limited central band of their full advancing width, and caused as a result to spread gradually into uniform contact with the overwrapped surfaces, without creasing.

Abstract: A method and device for feeding wrapping material and a tear strip to a user machine, whereby a strip of wrapping material and a tear strip are fed continuously along respective paths to a joining station where they are joined integral with each other to form a wrapping strip complete with a tear strip; a compensating store for compensating the wrapping strip being located between the joining station and a cutting station at which the wrapping strip is cut into a succession of portions.

Abstract: In a device by means of which to support dispensers of adhesive material for application to selected areas of a wrapping material, use is made of a slide equipped with a yoke providing a releasable restraint for at least one disposable type of dispenser consisting of or containing the adhesive. The slide reciprocates between at least two limit positions, following a path along which the adhesive is applied by the dispenser to a selected area.
