Abstract
A manufacturing machine includes a group-forming unit for forming filter portion groups, each group having at least two different filter portions aligned axially and contacting at the ends; a winding unit that receives a succession of groups from the group-forming unit, winds a strip of wrapping material about the groups to form a continuous filter rod, and cuts combination filters off the rod by cyclically cutting the rod transversely; and a transfer unit that transfers the groups from the group-forming unit, in which the groups travel transversely, to the winding unit, in which the groups travel axially. The transfer unit has at least one spider that feeds the groups successively into a forming beam of the winding unit, and at least one release drum that releases the groups successively to the spider. The release drum is mounted to move between a work position and a maintenance position.
