Abstract: In a drying process for increasing the filling power of tobacco material, the cut and moistened tobacco material is conveyed in a drying gas flow, dried within a tubular drying section and subsequently separated from the drying gas. The drying gas has at a feed point into the drying section a temperature of at least 200.degree. C. and a flow velocity of at least 30 m/sec. The flow velocity of the drying gas is reduced in the drying section. The flow velocity of the drying gas at the charge point into the drying section is at the most 100 m/sec. Within the drying section, to reduce the local heat transfer coefficient and the local mass transfer coefficient between the surface of the tobacco material and the surrounding drying gas, along with the reduction of the flow velocity of the drying gas, the flow velocity of the tobacco material is also reduced. At the end of the drying section the drying gas has a flow velocity of at the most 15 m/sec and a temperature of at the most 130.degree. C.

Abstract: A device provides a directed supply of tobacco ribs to a cutting tool. A vibrator conveyor conveys the tobacco ribs into the inlet area of a press conveyor disposed upstream of the cutting tool. The vibrator conveyor includes vertical partitions extending in the direction of tobacco rib transport. The intervals between the partitions are less than the average tobacco rib length. A device regulates the level of the tobacco rib flow transported between the partitions. Tobacco ribs can be precisely aligned in the axial direction prior to cutting, and can be transferred to the cutting tool without any loss of orientation.

The supply station is spanned by a portal. A portal robot movable longitudinally and transversely of the portal is provided for handling the bobbins of raw materials. Transport means are likewise provided for conveying the raw materials to the individual machines of the system and a bobbin changer is associated with each individual supply station for bobbins. The portal robot comprises an automatic tool changer.

Abstract: The invention relates to a method and an apparatus for the production of a coaxial tobacco or filter rod, a first production machine processing a strip-like first covering material and a stream of filling material to give a preformed rod which is deposited in a special magazine in order to be removed again therefrom in due course and supplied to a second production machine which brings the preformed rod together with a stream of filter or smoking material and a strip-like second covering material and processes it to form the coaxial tobacco or filter rod.
