Abstract

A method for making smokers' articles by subdividing a semifinished item which includes least five sticks aligned with each other along a main axis, at least two of the sticks are of a type different from the others; the method includes a step of forming the semifinished item by aligning the five sticks in a predetermined succession along the main axis and a step of subdividing a single rod into at least three sticks, followed by a step of aligning along the main axis each of the three sticks obtained from the rod alternating them with each of the sticks of different type, so as to form the semifinished item.

First claim

The invention claimed is:

1. A method for making smoker's articles, comprising: providing a single rod divisible into multiple sticks of a first type; providing at least two sticks of a different type from the first type; the following steps in successive order:
a step of subdividing the single rod into at least three sticks of the first type, comprising a first step of cutting the single rod into at least two parts, a first part of the at least two parts being a combination of at least two sticks of the at least three sticks and a second part of the at least two parts being a single stick of the at least three sticks;
a step of arranging the first and second parts to form a single row of the first and second parts positioned side by side one after another along a common line such that longitudinal axes of the first and second parts are parallel to each other, transverse to the common line and spaced apart from one another along the common line;
a step of forming a semifinished item by aligning at least five sticks in a predetermined succession along a second common line, the predetermined success including alternating the at least three sticks with each of the at least two sticks of the different type to form the semifinished item;
a step of subdividing the semifinished item;

2. The method according to claim 1 , wherein the step of subdividing the single rod further comprises a second step of cutting the first part into a first stick and a second stick of the at least two sticks of the at least three sticks with the single stick of the at least three sticks being a third stick of the at least three sticks.

3. The method according to claim 2 , and further comprising a step of spacing the second stick from the first stick; the single row of the first and second parts being formed by the third stick alternated with the first stick, the first stick being spaced from and aligned with the second stick.

4. The method according to claim 3 , and further comprising a step of feeding at least one succession of the at least two sticks of the different type and a step of aligning each of the at least two sticks of the different type, alternated with the first stick to form at least a fourth stick, and alternated with the third stick to form at least a fifth stick; the fourth stick being interposed between the first stick and the second stick to further form a first set of sticks; the third stick and the fifth stick forming a second set of sticks.

5. The method according to claim 4 , wherein the step of forming the semifinished item comprises a step of positioning the first set of sticks and the second set of sticks along the second common line.

6. The method according to claim 5 , wherein the step of positioning the first set of sticks and the second set of sticks along the second common line comprises a step of rotating by at least 180° one of the first set of sticks and the second set of sticks relative to the other of the first set of sticks and the second set of sticks.
