Problems solved by technology

[0008] This shortcoming cannot be overcome simply by increasing the initial velocity of the updraft passing through the chimney-like member; indeed, there are structural limitations to such an increase in velocity, other than causing the particles to hit the drawn air with too much force. Beyond the band, it was assumed that too high an initial velocity would have a tendency to compress the tobacco and degrade its physical properties

Embodiment Construction

[0017] Referring to Figure 1, numeral 1 generally designates a machine equipped to manufacture two consecutive cigarette rods simultaneously.

[0018] The machine 1 has a first section, referenced 2, through which a continuous flow of chopped tobacco particles is fed to a second section, referenced 3; during their passage through the second section 3, the particles are distributed and Two continuous tobacco streams 4 are formed.

[0019] In particular, the first part 2 comprises a substantially horizontal inner duct 5 housing a power drive transmission belt 6 which circulates at opposite ends around two pulleys 7, only visible in FIG. One of the two pulleys 7. The top of the conveyor belt 6 is positioned such that a carding unit of the usual type (as shown in Figure 1) takes the shredded tobacco and conveys it over a downstream pulley 7 by means of two counter-rotating rollers 9 and 10 about parallel horizontal axes into the uppermost communicating feed chamber 8 with the sl...

Abstract

In a twin-track cigarette maker (1) designed to manufacture two continuous cigarette rods at once, shredded tobacco particles entrained in an air current are directed up a channel (11) aligned on a substantially vertical axis (12). The channel (11) forms part of a chimney (13) enclosed at the top end (15) by two aspirating conveyor belts (16) and presenting a lower segment (21) equipped with a mechanism (22) intended to counter a loss of upward momentum tending to occur naturally in the flow of tobacco particles; the mechanism (22) comprises at least two flaps (23) hinged at the bottom and located internally of the channel (11), which are adjustable between a position parallel one with another, and a position converging toward an upper segment (24) of the chimney.

Description

technical field [0001] The invention relates to a cigarette making machine equipped to make two consecutive cigarette rods simultaneously. Background technique [0002] The twin track cigarette making machines used in the tobacco industry are equipped with a carding unit designed to generate a stream of chopped tobacco particles and work by making two continuous cigarette rods at a time. The tobacco stream is usually fed into an ascending duct or chimney, within which the particles are transported upwards and into contact with two suction bands arranged to close the chimney at the apex. [0003] The suction band runs at right angles to the direction following the upward flow of tobacco, the particles are held by the suction band to gradually collect into two continuous streams; these two streams are then surrounded by paper bands and form two continuous cigarettes Rods, each cigarette rod then advances along an associated path through the downstream processing station.
