Abstract: A method is provided for acting on a product in a machine operating in a machine cycle in the tobacco-processing industry in dependence on information about the product. Information about the product is detected synchronously with the machine cycle. The information is associated with the product asynchronously with respect to the machine cycle. An action is effected on the product synchronously with respect to the machine cycle in dependence on the information associated with the product.

Abstract: Apparatus for making rod-shaped tobacco products with a filter that includes a tobacco stick delivery device, a filter delivery device, a covering paper delivery device, a cigarette making device, a cigarette testing device, and a cigarette dispensing device. All the devices, in which each device includes at least one drum, are arranged to form a drum course. A drive element is structured and arranged to drive at least some of the drums of the drum course in positional synchronization with the transport of the rod-shaped tobacco products, and a drum unit is composed of at least one drum, which is not one of the at least some drums, and a bearing and control flange. At least one separate additional drive element is structured and arranged to drive the at least one drum, and a drive unit is composed of the separate drive element and the drum unit. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: A web of tipping paper for the making of filter cigarettes or a similar web of flexible wrapping material is advanced by two spaced-apart pairs of driven rolls through a processing station between the two pairs of rolls. The treatment includes flexing successive increments of the running web by a roller which is borne by a lever or an analogous carrier extending radially from the rotary output shaft of a torque motor capable of causing the roller to subject the web to an at least substantially constant stretching force regardless of the selected position of the carrier. To this end, the motor receives signals from a regulator which, in turn, receives signals from a sensor monitoring the web for the presence of splices and/or other weakened portions and/or from a device which monitors the position of the carrier. The apparatus can further comprise a stationary or a mobile curling tool which engages the web adjacent to the locus of contact between the roller and the web.
