Abstract
A method for producing at least one fiber skein for the production of filters for cigarettes and for other smokable rod-shaped articles, comprises the steps of drawing from a supply at least one filter tow strip, supplying the drawn fiber strip to a subsequent treatment, in which the fiber strip is stretched and fluffed, then the treated fiber strip is collected in a formating unit to a fiber skein which is finally provided with an enveloping material, to form a continuous, wrapped fiber skein. The fiber strip of strips are exposed at the beginning of the treatment to a brake force, to adjust at least the quantity to be processed of the fiber strip of strips, the brake force being set automatically. The apparatus comprises a feed device for continuous feeding at least one fiber strip from a supply to a treatment unit in which the fed fiber strip is stretched and fluffed; a formatting unit for forming at least one wrapped separate fiber skein from the treated fiber strip; and a brake unit (4) arranged at the inlet in the treatment unit (1), which exerts an automatically settable brake force on the fiber strip, to adjust the quantity to be processed of each fiber strip to a predetermined value.
