Abstract
A sealing element for the end portions of cigarettes or other rod-shaped articles of the tobacco processing industry has an elastic tubular body defining a longitudinally extending passage for the flow of air or another testing fluid from one end of an article being tested or in the opposite direction. The end face of the article being tested is engaged by a deformable membrane at one end of the passage, and such membrane has a central opening for the flow of testing fluid from or into an enlarged chamber between the membrane and an internal fluid deflecting baffle of the tubular body. The baffle causes the testing fluid to flow in the chamber radially inwardly toward or radially outwardly from the opening in the membrane and thus prevents the accumulation of tobacco particles and/or particles of filter material for tobacco smoke in the chamber. The stream of testing fluid in the major portion of the passage flows in the axial direction of the article being tested. The radial component or components of the flow of testing fluid reduce the likelihood of clogging of the chamber and/or other parts of the passage with solid particles.
