A device to check and discard lengths of wrapping paper (foil) intended to form the wrapper on packets of cigarettes in a very high speed packet cigarette packer; comprises at least one turning wheel in continuous motion on an axis parallel to the vertical feed plane for the lengths of wrapping paper and disposed opposite the front side of the stop check for the single lengths. Apparatus having idlers is placed, in respect to the feed plane, on the opposite side of the turning wheel in continuous motion mounted on an axis parallel to the axis of the wheel and spaced therefrom. An electromagnetic command controls the check for missing or faulty bundles of cigarettes. Mechanical linkage connects the idlers and the stop check with the means of command, so as to switch in respect of the vertical feed plane the stop check position and respectively on the idlers moving the former away from the same feed plane and bringing the second into contact with the turning wheel in continuous motion for the removal on the part of the aforesaid controls of any short or faulty bundle. |
