Plasticizer installation for the treatment of a rope of fibres

摘要

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.
