Boa testing of cigarettes or the like. and device boo performing the same

The invention relates to the testing of cigarettes and the like. rod-shaped objects with an air-permeable Filling and a cover of the same for undesirable leaks in the cover "

Suggestions have been made for testing cigarettes by means of processes in which each cigarette consists of a Stream of cross-axially moving cigarettes in straps is arranged, and where a Xuf tdruolcdifferene over the wrapping of each cigarette one after the other and the air flow through the envelope by means of pneumatic » matisober means established by the carrier would be in connection with the cigarettes relatively expensive to run and maintain.

The object of the invention is »an improved method for checking cigarettes and the like rod-shaped *! Create objects that are relatively simple and not expensive, as well as a device βοή exports, this procedure «

According to the invention, a method for testing cigarettes and similar rod-shaped objects, which can enclose a continuous wrapped rod of tobacco, is created, in which each object is moved through a test chamber which has an inlet and an outlet for the objects and which are in Connection is with means that keep the air pressure in the chamber at a pressure different from the atmospheric pressure, so that in one moment during its course the object closes the inlet and the outlet simultaneously and at least one of its ends is in contact with the atmosphere is standing, and checking the air pressure in the chamber at that moment to indicate a flow of air through the cigarette case, the breastfeeding and the test chamber.

Preferably the objects become axially through the chamber funded in continuous succession

The means that keep the test chamber pressure at a value deviating from the atmospheric pressure can

Absorbents, which cause the brackets to be below the atmospheric pressure, and the pressure difference achieved is relatively high compared to the lower pressures that have been used to date for air testing of cigarettes. It can, for example, be in the order of magnitude of 1 ia water. This has the advantage that the effect of a leaky tunnel increases and therefore the test becomes more sensitive and precise

The invention extends to a method of making cigarettes in which a continuous stream of axially moving wrapped sabakat rugs is checked for air leaks in the wrapping while they are moving axially leave, in which the JDabak is wrapped in paper to form a continuous' wrapped tobacco rod, which is then cut into appropriate lengths. This is of particular advantage when means are provided for arranging the strand pieces at a distance from one another while they are moving axially, as is the case, for example _, in the manufacture of MunäatUok cigarettes. Alternatively, the test could be carried out on the continuous strand itself before it is cut

The invention can also be a method. for testing cigarettes and the like, include rod-shaped objects having a wrapper for leaks in the wrapper, forming a chamber around each item, between its ends, thereby creating an air pressure drop between the inside and the wetter of the wrapper Generated over the envelope so as to try to create air flow through the envelope and by checking the air pressure in the chamber to indicate the flow of air through the envelope «

Possibly designed taking into account the tolerances the cigarette diameter · The chamber 1 is provided with an opening 7, which is in connection with a suction source and a pressure-sensitive test device, which in turn is in connection with rejection means, the one Eliminate faulty cigarettes from the production stream *. .

If a cigarette 4 is running through chamber 1 during the time it is in both inlet 2 and ... Outlet 3 is closed, the Druok in the chamber. 1 reduced. If there is a leak in the cigarette wrapper, if the cigarette passes through chamber 1 runs, airs through the cigarette flow from the ends, which are exposed to the atmosphere, and through the hole in the enclosure, and that air becomes the Druok in the Increase test chamber 1. This rise in pressure is noted by means of the pressure sensitive test device as an abnormal pressure. This facility then causes that the cigarette will be rejected.

Alternatively, the test can be carried out in the continuous strand itself, i.e. before the strand is cut will. In this case, the chamber 1 is arranged on the cutting device as closely as possible, and also upstream of the cutting device.
