DEVICE FOR SIMULTANEOUS, CONTINUOUS MEASUREMENT AND CONTROL OF THE ACETATE AND TRACE ACCEPTANCE IN FILTER BARS IN THE CIGARETTE INDUSTRY

摘要

The invention relates to a device for producing cigarette filters, which comprises a conditioning section (AF) for conditioning the supplied filter tows, a formatting device (F) for producing a wrapped filter strand, a dosing device integrated into the conditioning section for dosing a softener. The device further comprises sensors that detect the mass flow of filter tow material M1 and sensors that detect the sum of the mass flow from filter tow material and softener compound M2. A measuring and regulation unit is coupled with the sensors for measuring the mass flows (M1 and M2) in such a manner that both the filter material and the softener compound can be measured and regulated independently.
