A feeler device for sensing the number of cigarettes arranged in groups, particularly groups of three rows, at the interior of a group-forming pocket, includes a plurality of feeler pins which are arranged parallel in the longitudinal direction of the cigarettes and which can be introduced into the group-forming pocket through an open end thereof in order to detect the cigarettes which are misplaced or dislocated, the feeler pins are arranged excentrically and the line connecting the feeler pins of each cigarette row is a zig-zag line.

The rocking lever for a cam mechanism presents a hollow box-type structure and consists of a modular base piece provided with the trunnions and with the cam follower rollers adapted to cooperate with the cams. The modular base piece presents two connection surfaces, arranged at 90.degree. with respect to each other, and adapted for the fastening of modular appendix pieces. The said modular appendix pieces can be secured in a removable and changeable manner to the modular base piece.

Apparatus for the formation of cigarette groups consisting of three superposed parallel rows of cigarettes comprising three row-forming stations which receive the cigarettes from passageways connected to a feeding hopper. Associated with each row-forming station there is an intermediate transfer drum which presents a plurality of transfer pockets adapted to receive the rows of cigarettes from the row-forming stations. The cigarettes are then transferred from the pockets of the transfer drums into the receiving pockets of a receiving drum. Each transfer drum supplies to the receiving pockets of the receiving drum a definite row of cigarettes, so that at the end of an operating cycle, the receiving pockets will be filled with three superposed rows of cigarettes. From the receiving pockets, the groups of cigarettes are transferred to a compressor drum, associated with a cigarette packing machine. The transfer drums, the receiving drum and the compressor drum are rotated stepwise in synchronism.

Apparatus for the formation of cigarette groups

A device for the formation of groups of cigarettes of at least one row of cigarettes arranged parallel side-by-side which comprises a feeding hopper subdivided by partition walls into a plurality of adjacent passageways which open into a collecting chamber delimited by a bottom plate and by side pushers. The partition wall located in the middle zone of the row of cigarettes, extends down to the bottom plate and engages by its terminal portion a groove provided in the said bottom plate. In this manner, the cigarette row being formed is divided into two row portions.

The receiving pocket of a cigarette group forming apparatus consists of an open-ended tubular member provided at its interior with two partitions defining three pocket sections, one for each row of cigarettes forming the cigarette group. The partitions extend at the interior of the receiving pocket, from the introduction or inlet end towards the outlet end, for a fraction of the length on the receiving pocket, usually for 1/3 of its length. The partitions become thinner in the direction of the outlet end, and they are also converging in the said direction. Also the inner upper and lower side walls of the receiving pocket converge in the direction of the outlet end.
