Abstract
During the production of filter cigarettes (10), these are subjected to testing with the aid of test air. For this purpose, air is introduced into the filter cigarette (10) at one end. The air emerging at the opposite end is measured. The filter cigarette (10) is subdivided into testing sections or testing chambers (22, 23) for the purpose of more accurate testing and in order to derive more accurate information, in particular for testing a tobacco stick (11), on the one hand, and a filter (12), on the other hand. The testing chambers (22, 23), which are sealed off from one another, are connected to separate sensors.
Claims13
A device for producing filter cigarettes (10), in which an outer filter cover—cork paper—has openings (13) which are introduced into the filter cover by a perforation element, in particular by a laser perforation element, the openings (13) being checked by introducing a flowing medium—test air—at one end of the filter (12) and measuring the air—exit air—emerging via the openings (13), characterized by the following feature:
- a) the perforation element is arranged in the region of the device for producing the filter cigarette (10),
- b) the perforation element can be adjusted with regard to the number and/or size of the openings (13) to be made in the filter cover,
- c) results of the measurement of the exit air in the region of the openings (13) can be supplied to a computer (44),
- d) the perforation element is connected to the computer (44) and, by means of the latter, the number of openings (13) to be made and/or the size of the same can be adjusted in accordance with the measured results.
