摘要： The degree of ventilation of ventilation zones in the wrappers of filter cigarettes is ascertained by confining the ventilation zones of successive cigarettes in a chamber during travel through a testing station and by increasing the pressure in the chamber above or by reducing the pressure in the chamber below atmospheric pressure. The pressure at that end of each cigarette which is adjacent the ventilation zone is monitored at the testing station, and the resulting signal is indicative of the degree of ventilation. Such signal can be divided by a signal denoting the pressure in the chamber during testing, and the resulting signal can be multiplied by 100 to obtain a signal which is indicative of the degree of ventilation in percent. The signal which denotes the degree of ventilation can be displayed, used to modify the operation of the apparatus which provides the wrappers of cigarettes with ventilation zones, and/or used to segregate cigarettes with unacceptable ventilation zones from satisfactory cigarettes.

摘要： A cigarette testing apparatus wherein each end of the wrapper of a cigarette advancing with a rotary conveyor past a testing station receives a stream of gaseous testing fluid from a conduit which is connected with a source of testing fluid, and wherein a further conduit connects the interior of the wrapper at the testing station with an electropneumatic transducer which generates signals denoting the condition of successively tested wrappers. In order to prevent columns of testing fluid in the conduits from oscillating as a result of abrupt establishment and/or abrupt termination of communication between such conduits and the wrappers of cigarettes moving toward, past and beyond the testing station and from thereby distorting the signals which are generated by the transducer, at least one such conduit admits a stream of fluid into an oscillation-preventing device having an injector nozzle serving to convert the inflowing stream into a coherent laminar flow which traverses, without guidance, a chamber whose interior is maintained at atmospheric pressure, and which thereupon advances toward the testing station or toward the transducer by flowing through an intercepting orifice. Alternatively, the nozzle can receive testing fluid from the chamber and then directs the laminar flow toward one end of the wrapper of the cigarette at the testing station.

摘要： A cigarette testing apparatus wherein a rotary drum-shaped conveyor has axially parallel peripheral flutes for cigarettes and is flanked by two swash plates which rotate therewith and carry annuli of elastically deformable sealing elements for the respective ends of cigarettes on the conveyor. Each sealing element has a socket facing the adjacent end of the cigarette in the corresponding flutes of the conveyor when the cigarette is inserted into the flutes. The swash plates thereupon move the sealing elements nearer to the ends of the cigarettes therebetween whereby the ends of the cigarettes enter the corresponding sockets and displace transversely extending partitions of the sealing elements with attendant radial contraction of those tubular sections of the sealing elements which surround the respective sockets. This moves the internal surfaces of such sections into sealing engagement with the external surfaces of the ends of the cigarettes during transport of cigarettes through the testing station where the cigarettes receive streams of testing fluid flowing through centrally located apertures of the adjacent partitions. The sealing elements have thin-walled annular membranes flanking the respective partitions to allow for movement of the partitions in response to the application of pressure by the respective ends of a cigarette as well as to facilitate radial deformation of the tubular sections in response to such displacement of the partitions. The sealing elements reassume their undeformed states when they move away from the respective ends of the cigarette therebetween in response to further rotation of the swash plates.
