Method and a system for production of rod-shaped articles

A method of manufacturing rod-like articles, where

• the rod-like articles are manufactured on a machine for manufacturing the rod-like articles or the rod-like articles are delivered from a feeding device,
• a measurement is effected with a first measuring accuracy on a first measuring unit for measuring of at least one quality parameter of the manufactured rod-like articles, whereas the said quality parameter has a predefined range of acceptable values of the parameter,
• the stream of the rod-like articles is divided into a first stream comprising the rod-like articles, for which the said quality parameter falls within the range of the acceptable values of the parameter and a second stream of the rod-like articles, for which the said at least one quality parameter does not fall within the range of the acceptable values of the parameter,
• the first stream is transferred as an output stream of a system of manufacturing the rod-like articles by means of a first transferring device,
• wherein
• the second stream of the rod-like articles is transferred through a repeated quality inspection path on a measuring conveyor and a repeated measurement is effected in a second measuring unit with a second measuring accuracy higher than the first measuring accuracy of the first measuring unit,
• the inspected rod-like article is transferred by means of a second transferring device to the output stream of the rod-like articles on the first transferring device, if the result of the repeated inspection of the said quality parameter for the individual rod-like article falls within the range of the acceptable values of the said parameter.
