ABSTRACT:
Filler material, particularly for cigarette filters, is produced by feeding a first stream of substantially continuous filaments of filler material onto a pin roller which is driven at a speed such that the filaments are broken by the pins into irregular lengths and are projected from the roller in random orientations. The broken filaments are collected on a carrier stream, also comprising filamentary material, for delivery to a rod-making unit. More than one stream could be supplied to the pin roller so that the broken filaments can comprise a mixture of filaments of different filler materials. The carrier stream may comprise filler material which is different from that in the first stream and may comprise a fibrillated web.
