Abstract
An apparatus for sequentially measuring the physical properties of air-permeable rod-like articles such as cigarettes or filter rods. The apparatus is self contained and includes stations for measuring the circumference, weight and pressure drop of each article. The measurement of circumference and pressure drop are carried out pneumatically. An indexing drum is provided to transfer each article to the subsequent measuring station.
Claims10
An apparatus for automatically measuring a plurality of physical properties of air-permeable rod-like articles comprising:
- (a) a plurality of measuring stations,
- (b) an indexing drum arranged to receive an article and to rotate to present the article sequentially at each of the measuring stations,
- (c) means for transferring the article from the drum to the measuring station at which it is presented,
- (d) means at said measuring station to measure a respective physical property of the article,
- (e) means for generating a signal indicative of the magnitude of the physical property measured at the measuring station,
- (f) means for transferring the article from the measuring station back to the drum in readiness for being presented at the next measuring station, and
- (g) means for measuring and recording said signals.
