(57) Waste or other recovered fibrous material, for example fibres from waste or reject
cigarette filters, filter rods and tows employed in making them, is converted into
useful products by depositing the fibres 11, preferably dispersed in an aqueous medium
12, on an advancing screen 16 to form a fibrous web. The web is caused to adhere to
a carrier or backing sheet 14, either during or after deposition, and the assembly
20 of fibres and carrier is sub-divided into portions for the manufacture of fibrous
products, preferably after being dried in a ventilated drier 21. Plasticizer may be
applied by an applicator 22 for the purposes of softening and bonding the fibres in
subsequent stages of the production of the desired fibrous products. The divided portions
of the assembly 20 can be used to form such products as cigarette filters or absorbent
ink carrier elements for pens.
