Abstract (en)
An apparatus for blooming cigarette filter tow band (1) comprises a first pair (10, 11) and a second pair (20, 21) of rotatably arranged rollers. The second pair of rollers (20, 21) is arranged downstream of the first pair of rollers (10, 11) with respect to the direction of transport of the filter tow band (1) and is rotatable at a driving speed which is higher than the driving speed of the first pair of rollers (10, 11) so as to cause stretching of the filter tow band (1). Stretching of the filter tow band (1) is released once the filter tow band has passed through the second pair of rollers (20, 21) allowing blooming of the filter tow band to occur. A diverter (4) is adjacently arranged downstream the second pair of rollers (20, 21).
