ABSTRACT:
A device for measuring the draft of cigarettes comprises a vertical tubular body in which cigarettes are fed one by one. A first sphincter-member mounted inside the body is operable to prevent a cigarette from falling and stop it in a given position. A second sphincter-member positioned above the first member is actuated when the first member is released so as to hold the cigarette in the above given position. A seal is provided at the bottom side of the tubular body to define a gas-tight chamber with the second sphincter-member, and an orifice connected to a source of air under vacuum is formed in the body between the first sphincter-member and the seal.
