A machine for making grooved smoking article rods has an axially rotatable drum (5) with a generally cylindrical outer surface (8). A pressing member (10) has a pressing surface (11) that includes grooves (12) facing the outer surface of the drum. The pressing member is heated by a heater (13). Filter rod segments (1) are fed from an inlet supply (9) between the pressing surface (11) and the drum (5) to be rotated and pressed against the grooves (12) so that a pattern of grooves (15) is formed in the outer surface of the filter segment.
