摘要:
A device for conveying products, in particular packets of cigarettes, whereby two wheels, rotating in opposite directions about respective axes parallel to each other, transfer from one to the other a succession of products at a transfer station; one of the wheels has a succession of fixed radial seats, and the other wheel has a succession of movable seats, each of which is fitted to the wheel so as to rotate about two axes parallel to the rotation axis of the wheel and so remain parallel to and facing a corresponding fixed seat during travel through the transfer station.

A line for feeding a strip of wrapping material, whereby the strip is wound off an input reel and fed along a substantially U-shaped path to a traction unit via an adjusting unit for adjusting the tension of the strip; the adjusting unit is provided with a chamber in turn having a window located along the path of the strip. The chamber is tapered away from the window and the strip is subjected to a tension varying according to the length of strip drawn into the chamber.

A method of wrapping products, whereby gripping assemblies, each for receiving a respective product and a respective sheet of wrapping material, are fed successively in steps and in a given traveling direction along a path extending through a loading station where each assembly is supplied with a respective sheet of wrapping material; and whereby, at each step, two assemblies, located one behind the other along the path, are brought into the loading station and arrested in respective loading positions to simultaneously receive respective sheets of wrapping material, which are fed to the respective loading positions along respective supply paths located side by side.
摘要:
A method and machine whereby at least two strips of paper, after being supplied with respective continuous layers of shredded tobacco, are fed along a forming beam by respective conveyor belts which are deformed transversely to gradually wind the respective strips about the respective layers and so form respective tubular wrappings, each presenting a respective longitudinal lateral appendix, an inner lateral portion of which is gummed by a respective gumming disk and then brought into contact with an outer surface of the respective tubular wrapping to form a respective continuous cigarette rod; the inner lateral portions being gummed at an intermediate point of the forming beam. The gumming apparatus is located to one side of the forming beam, thereby leaving the other side accessible.

On a filter assembly machine, a rolling device provides for joining, by means of a succession of strips, a number of elongated elements in a corresponding succession of groups using a number of rollers, each presenting a respective seat for a respective group, and each rotating about a respective axis for rolling the groups in contact with a rolling surface; the axes of the rollers being moved, in relation to the rolling surface, at a first speed; and the rollers being so operated as to rotate about the respective axes and advance the respective seats at a second variable speed which is minimum when the groups are loaded and unloaded on and off the rollers.
摘要:
A method and device for applying sealing strips to packages, whereby the strips are applied to the packages as these are transferred between respective transverse pockets on three conveyors traveling at the same speed and in the same direction, the first conveyor being a loop conveyor located between a feed conveyor and an output conveyor. The strips are supplied in such a position as to close the end of the pockets on the loop conveyor facing the feed conveyor, and the packages complete one full turn of the loop conveyor prior to being transferred on to the output conveyor.
摘要:
A method and device for producing tubular wrappings for products of parallelepiped shape or similar; whereby the products are fed successively, and in a substantially radial direction, to a wrapping wheel turning at substantially constant speed and having a number of mobile elements, each defining a seat for a respective product. Each product is inserted inside a respective seat together with a sheet of wrapping material, which is folded in a U and presents two opposite portions projecting outwards of the seat. One of the portions is folded down on to the product by a first folding element, and the mobile element is moved on the wheel so as to fold and hold down the other portion by means of a second folding element mounted on the wheel, and so as to move the seat into a position facing a joining device for firmly joining the two folded opposite portions of the sheet of wrapping material.
摘要:
A cigarette packaging machine provided with a wrapping wheel to wrap products in wrapping sheets. The wrapping wheel has peripheral pockets to receive the products and the wrapping sheets, a first loading station to load the products in succession into the peripheral pockets, and a second loading station to load, in succession, first wrapping sheets of the wrapping sheets into the peripheral pockets. The wrapping wheel also has a third loading station to load, in succession, second wrapping sheets of the wrapping sheets into the peripheral pockets, thus reducing the bulk of a packaging machine.
摘要:
A device (1) for packaging a product shaped as a set of cigarettes in a corresponding container (A), defining a package for housing the product, comprises means (11) for forming the container (A) and appropriate means (21, 21) to dispense a corresponding adhesive (B1, B2) for joining corresponding panels of the container. Said appropriate means (21) to dispense a corresponding adhesive are provided next to the exit from the forming means (11) and are movable with respect to said container (A).
