  • Patent number: 4249546
    Abstract: An apparatus for filling empty cigarette blanks in which tobacco is placed in a tobacco magazine. When an operating lever is actuated, a pressure plate compresses the tobacco into a column. Upon further actuation of the lever, an elastic rack expels these columns so formed through a boss on which the cigarette blank is held by pincers. In order to adapt the apparatus to cigarette blanks of various lengths, in particular to cigarette blanks having single or dual filters, there is provided a movable slide which limits the amount of tobacco placed in the tobacco magazine to correspond to the amount required by a particular cigarette blank.
