Estimating the term…
Fragments of plastic fibers, such as cellulose acetate fibers, forming part of mouthpieces of filter cigarettes or like rod-shaped smokers' products tend to become separated from the respective filter mouthpieces at the end faces which develop in response to the making of cuts across filter rod sections of double unit length between pairs of plain cigarettes to obtain filter cigarettes of unit length. The fragments of fibers which tend to become separated and to contaminate the area around the filter cigarette making machine are either bonded (e.g., by heat and/or by a solvent) to the respective mouthpieces, or are removed by suction and/or by resorting to electrostatic precipitation. It is also contemplated to cause smoke-permeable layers of filter material to overlie the end faces of the mouthpieces.
A method of processing smokers' products wherein a plurality of aligned rod-shaped components include at least one multiple-unit-length filter rod section containing plastic fibers and a pair of tobacco-containing components flanking the at least one section, comprising the steps of severing the products across their sections so that the severed sections develop pairs of mouthpieces having end faces at which at least some of the fibers tend to become separated from the respective mouthpieces;
Apparatus for processing smokers' products wherein a plurality of aligned rod-shaped components include at least one multiple-unit-length filter rod section containing plastic fibers and a pair of tobacco-containing components flanking the at least one section, comprising means for severing the products across their sections so that the severed sections develop pairs of mouthpieces having end faces at which at least some of the fibers tend to become separated from the respective mouthpieces;
