Control process and apparatus for the production of cigarette filters. |
摘要 |
<p>To improve quality control a cigarette filter manufacturing line is provided with a testing station (28) which periodically removes a filter to test the diameter (at 34) and resistance to draw (at 33). The mean diameter and RTD of a number of filters is calculated (at 36) and compared to acceptable ranges. Adjustments are made to the manufacturing line to correct any unacceptable values according to a set of priorities dependent on the degree and sense of the inaccuracies.</p> |
