ABSTRACT:
This invention relates to the machines for manufacturing filter-tip cigarettes by forming successive groups (S+2F+S) each formed by two aligned cigarettes (S) and one interposed double filter (2F), and by wrapping and glueing a covering strip (T) around the double filter (2F) and adjacent ends of the two cigarettes (S). The formation of the groups (S+2F+S) is carried out on a composition drum (1) whereon the double filters (2F) and the pairs of cigarettes (S) are held by suction. The application of the strip (T) may be carried out either on said composition drum (1) or on a successive assembling drum (6), and the strips are fed by a strip-carrying drum (7) whereon they are held by suction. In the absence of a component, e.g. a double filter (2F), in a group (S+2F+S), all the other components of the same group, i.e. the two cigarettes (S) and covering strip (T), are discarded automatically by affecting for this purpose only the suction exerted on the components to be discarded.
