DEVICE FOR COMBINING GROUPS OF FILTER SEGMENTS FOR PRODUCING MULTI-SEGMENT FILTERS OF THE TOBACCO INDUSTRY, AND TROUGH DRUM

摘要

The invention relates to a device for combining groups of filter segments (6, 7, 80-83, 87) for producing multi-segment filters (49) of the tobacco industry in a continuous process, according to which two multi-segment filters each of at least two different types of filter segments (6, 7, 80-83, 87) are provided. The invention further relates to a trough drum (90) for positioning, in a longitudinal direction, rod-shaped articles (80-83) of the tobacco industry that are to be separated and/or that are already separated, in receiving troughs (84) using mobile alignment stops (93, 94). The invention is further characterized in that the device can be subdivided into a plurality of autonomous functional units (604, 605, 61). The inventive device is further provided with at least one positioning device (92, 106-108) for positioning, at a distance to each other, two rod-shaped articles (83) disposed side by side in a receiving trough (84) in a longitudinal relation.
