Problems solved by technology

Though effective functionally, this solution involved a significantly increased cost burden, due mainly to the duplication of mechanical components, but also to the additional testing, servicing and manning requirements involved.
Further improvements since made to the functional effectiveness of packers have shown clearly that even cigarette makers capable of assembling two rods simultaneously are not capable of matching the increased output capacity of the new packers.
In addition, the solution of assembling more than two cigarette rods one alongside another has been rendered problematical hitherto by difficulties connected, in particular, with the step of cutting the rods into sticks, which typically involves the use of a single rotating cutter device equipped in most cases with two peripheral blades.
The operation of cutting such a rod calls for faultless adjustment of the cutter device, as the time for which each cutting edge remains in contact with the rod would be much longer than in the case of a conventional single-rod type machine.

Embodiment Construction

[0023] Referring to FIG. 1 of the drawings, 1 denotes a portion, in its entirety, of a cigarette making machine able to fashion a plurality of continuous cigarette rods 2a, 2b and 2c simultaneously, as indicated by the section drawing of FIG. 3.

[0024] In particular, albeit implying no limitation, the drawings illustrate a machine able to form three cigarette rods 2a, 2b and 2c simultaneously.

[0025] The machine 1 comprises a frame 3 carrying a feed unit by means of which to advance three strips 4 of paper, each marginally greater in width than the developable circumference of the single rods 2a, 2b and 2c in production. The feed unit in question is essentially familiar in embodiment, and indicated schematically by a block 5 in FIG. 1.

[0026] The machine 1 further comprises a feeder device 6 supplying shredded tobacco 7, also a table 8 on which the continuous cigarette rods 2a, 2b and 2c are assembled.

[0027] The assembly table 8, likewise carried by the frame 3, comprises three con...

Abstract

In a cigarette maker equipped with a surface on which continuous cigarette rods are assembled from respective strips of paper and streams of shredded tobacco, a cutter by which the rods are divided up into cigarette sticks, and guide ways by which the assembled rods are directed toward the cutter, the table or the guide ways, or both, will be positioned so that the rods advance along respective paths converging one with another.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a cigarette maker. [0002] More particularly, the present invention relates to a cigarette-making machine of the type equipped with means by which to form two or more continuous cigarette rods. [0003] It is the practice when manufacturing cigarettes to fashion a continuous cigarette rod from starting materials that consist in a strip of paper decoiled from a roll on the one hand, and a mass of shredded tobacco on the other. [0004] In the course of the following specification, the term cigarette rod indicates the assemblage of the paper strip and the tobacco, from the moment when the tobacco is deposited on the paper through the step whereby the paper is wrapped around the stream of tobacco. The continuous rod formed in this way is fed toward a cutter device and divided up into single sticks, each of which will provide at least one cigarette. [0005] Having undergone further processing operations if envisaged, such as ...
