<p>In a cigarette manufacturing machine, the trimmer device for the tobacco filler comprises two cone frustum trimming discs which are tangential to each other at their major base, this latter being provided with a cutting edge, and are mounted on inclined shafts which converge downwards. The cone-frustum surfaces of said discs are provided with equidistant grooves, of which the pitch, measured along the cutting edge, is equal to the length of the cigarettes under production, and their radial dimensions are a function of this length. Structure is provided for setting the position of said discs on their respective shafts according to their diameter, and additional structure is provided for setting the position of the trimmer device relative to the tobacco filler. A rotating brush is also provided cooperating with said discs in the trimming zone, and structure for setting the position of said brush relative to said discs.</p> |
