Abstract: Apparatus for the automatic removal of a sample from a production line comprises a rotary removal arm connected to a vacuum source for bringing the sample into a position opposite a diametral bore in a rotary disc. The disc is intended to bring the sample into a transfer position. The disc may be associated with devices for checking the pressure drop and weight of the sample. The sample may be reintroduced back into the production line.

Abstract: A plasticizer installation comprises a chamber through which a fibre rope passes in front of a spray device comprising a turbine, connected to a source of high voltage and located between a truly rectilinear path and the actual rope path, which paths define a trapezium. The plasticizer mist carried along by the rope is recovered in a decompression booth. The supply of plasticizer is controlled according to the weight of an intermediate vat also receiving the flow from the booth.The plasticized rope of fibres is intended to be used in the production of cigarette filters.
