<p>Disclosed herein is a device for checking that the bands joining filters to cigarettes have been sealed down, wherein through first pneumatic means, the cigarettes placed side by side inside housing defined by transfer means, are thrust towards opening aligned axially with the said housing, the section of which is slightly greater than that of the individual cigarette. Opposite the said first pneumatic means there are first means for halting the cigarettes that pass through the said openings with only the part around which the filter-cigarette joining band is wound. Downstream of these there are means for intercepting and ejecting cigarettes having an open band which do not arrive against the said first halting means and after these, second pneumatic means that operate in the opposite direction to the first pneumatic means, opposite which there are second means for halting the cigarettes moving inside the housing defined by the transfer means under the action of the said second pneumatic means,which return the checked cigarettes to their initial alignment.</p> |
