The conveyer flights 32 are located to space, correctly, the groups C of cigars on the wrapping material 14 as the latter is drawn over the platform 10. As the material 14 advances it is folded into tubular form, by ploughs not shown, and to define a vertical fin 34 which is drivingly engaged by the pairs of rollers 36, 36, and 40, 40, the fin 34 passing through heater elements 38, 38 which co-operate with the rollers 40, 40 to effect a seal on the fin 34 the latter remaining heated while it is subsequently folded down by a plough 42.
