摘要:
In a method of feeding wrapper material, typically as utilized by machines for the manufacture of tobacco products, a first and a second strip presenting two longitudinal side edges and of dissimilar transverse dimensions are advanced along respective predetermined first feed lines, positioned one relative to another in a direction transverse to the respective first feed lines in such a way as to bring about their alignment along one longitudinal edge and finally joined face to face before advancing together along a predetermined common feed line toward a machine unit.

A continuous tobacco rod generated by a machine for making tobacco products is separated into reclaimable lengths by a device that comprises a pair of tension rollers designed to exert a pulling force on the rod, also a pair of brake rollers operating upstream of the tension rollers and serving to offer a measure of resistance to the action of the tension rollers; as a result of the interaction between the tension rollers and the brake rollers, the portion of the continuous rod extending between them is forced to break by tearing apart.

In a cigarette maker comprising a descent channel filled with shredded tobacco by a carding unit and with reclaimed tobacco by a conveyor, the shredded tobacco and the reclaimed tobacco are taken up and transferred by a toothed unit toward an ascent channel, from where both are attracted onto a belt by suction and formed into a continuous stream; the descent channel is split into two distinct portions serving respectively to admit the shredded tobacco and the reclaimed tobacco, whilst the toothed unit comprises a first and a second roller positioned to take up the shredded tobacco and reclaimed tobacco and operating in conjunction with respective impeller rollers.

A continuous cigarette rod is prepared by a unit comprising a looped conveyor on which a continuous stream of tobacco particles advances toward the entry point of a forming station where the rod is assembled. Also forming part of the unit, ordered in sequence along a predetermined feed path, are a first trimming device designed to produce a cyclical skimming action, a compactor device operating synchronously with the first trimming device, serving to increase the density of the stream selectively at points coinciding with the portions skimmed by the first trimming device, and a second trimming device by which the thickness of the stream is reduced uniformly to a prescribed value.
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.
摘要:
A unit for transferring cigarette portions from a dual rod cigarette manufacturing machine to a filter assembly machine; the transfer unit presenting a launching device for successively receiving pairs of cigarette portions arranged side by side and traveling in an axial direction, and for simultaneously feeding the portions in each pair--still substantially axially, but imparting to them a transverse component--into respective adjacent seats of a conveyor device wherein the seats for receiving the cigarette portions are parallel to the cigarette portions, and travel crosswise to the traveling direction of the cigarette portions.
摘要:
A method and machine whereby a stream of shredded tobacco is fed through a dividing device for dividing the stream into two substreams and feeding the two separate substreams to a forming device downstream from the dividing device; the dividing device presenting two suction belts in turn presenting respective dividing branches crosswise to the stream, and each of which belts provides for retaining a respective portion of the stream by suction to form a respective substream.

In a machine and a method for manufacturing composite filters (F1, F2) for cigarettes or the like, a feed conveyor (S) supplies filter groups (G1, G2) in pairs to two respective feed lines (L1, L2) of a station (16) for forming two continuous filter rods (B1, B2); the machine (100) comprises at least one transfer device (DT) by which the filter groups (G1, G2) are taken up from the feed conveyor (S) and directed along the feed lines (L1, L2), and at least one release device (R), operating along the two feed lines (L1, L2), by which the two filter groups (G1, G2) are taken up from the transfer device (DT) and released in phase one with another along the selfsame feed lines (L1, L2); the rate at which the filter groups (G1, G2) are released by the release device (R) is governed according to the phase value of at least one of the continuous filter rods (B1, B2) relative to the cyclic cutting operation whereby the two filter rods (B1, B2) are cut transversally to make the composite filters (F1, F2).
摘要:
A transfer or feed drum for filter or cigarette portions, the drum having: a central body mounted to rotate about a first axis of rotation; a number of movable assemblies, each of which is fitted to the central body to rotate, with respect to the central body, about a respective second axis of rotation parallel to the first axis of rotation, and supports a pickup or feed head having at least one seat with a U-shaped cross section and for engaging at least one filter or cigarette portion; and an actuating system, which controls the angular position of each movable assembly about the respective second axis of rotation as a function of the angular position of the central body about the first axis of rotation.
摘要:
The invention relates to a method for forming a cigarette rod containing an additive material in a cigarette making machine, in which a continuous tobacco rod is fed along a vacuum conveyor and particles of the additive material are fed to and incorporated along the axis of the cigarette rod by a distributor which comprises a conveyor having a hollow drum with a cylindrical side wall on which there is a plurality of seats designed to house the particles; the drum rotating within a ring-shaped structure and the seats, during rotation of the drum, passing through an ejector unit designed to eject the particles from the seats and incorporate them in the tobacco rod through a feed pipe, so as to control the distribution of the particles of the additive material along the tobacco rod, obtaining a preset positioning of the particles in each cigarette length.
