Alternatively, the sleeves or equivalent cigarette-receiving The sleeves may be provided with gripping means such as springs for holding the cigarettes in position in the sleeves and for preventing the rotation of the cigarettes in relation to the sleeves.

The cigarettes may be fed to the intermittently movable carrying means from the continuous rod machine and in order to allow for suicient time interval for the application of the bands of paper, cork or the like, two intermittently movable carriers may -be provided. and the cigarettes may be fed alternately to the carriers by means of an'oscillatable member having two parallel chambers or bores therein. Conveniently, the intermittently movable carrying '31, In Great Britain July 14, 19?*3 5 `(ci. 1er-39) l H II Figure l;
