Abstract
Method and apparatus for the separation of foreign bodies from a material flow, in particular a tobacco stream. Method is characterized in that at least a portion of the material from the material flow is conveyed into the area of a foreign-body detection device in the form of a partial material flow, whereby foreign bodies are identified by the foreign-body detection device in the partial material flow and subsequently removed from the partial material flow, whereby the partial material flow is formed by a separation step by an air flow upstream from the foreign-body detection device. Apparatus is characterized in that a material flow conveyor and a separation device arranged diagonal to the material flow conveyor are provided by which a partial material flow can be separated from the material flow. A foreign-body detection device is arranged after the separation device and after this, a foreign-body separation device.
