Apparatus for conveying filter rod sections from storage or from a maker to a reservoir or to a filter tipping machine for cigarettes or other rod-shaped articles of the tobacco processing industry has a first conveyor which advances the filter rod sections lengthwise, a second conveyor which advances the sections sideways, and a unit which transfers successive sections of a series of sections delivered by the first conveyor to the second conveyor. The advancement of sections by the first conveyor is interrupted if the spacing between successive sections in the first conveyor is less than required for disturbance-free transfer of sections from the first conveyor into the second conveyor. One or more sensors are provided to minitor the movements of sections at the transfer unit and to generate signals which are utilized to remove sections from the transfer unit when the pattern of movement of sections from the first conveyor to the second conveyor departs from a desired pattern.

Apparatus for transporting sections of filter rods

Filter rod sections are transported sideways from a magazine containing a pile of parallel sections toward positions of alignment with the inlet of a pneumatic conveyor and are propelled into the conveyor at a transfer station where they continue to move sideways. In order to avoid damage to sections during propulsion into the conveyor, the duration of complete transfer of successive sections into the inlet is monitored in order to generate signals denoting the intervals of axial advancement of successive sections all the way into the conveyor. Such signals are compared with signals denoting those intervals of sidewise movement of sections past the transfer station during which the sections can move axially without being damaged by the stationary inlet of the conveyor. The evaluating circuit which compares the signals generates defect signals when the transfer of sections in unsatisfactory, and such defect signals are used to reestablish the possibility to advance undamaged sections into the conveyor or to expel the fragments of destroyed or partially destroyed sections from the conveyor and/or from those parts of the apparatus which supply articles to the transfer station.
