  • Patent number: 8353810
    Abstract: A method of making segmented filters including moving substantially identical segments of one type at uniform rate to a transferring element, which places each segment separately on an exit path. Setting of the filter segments in a repeating group on the exit path is accomplished by delay in collecting segments by a transferring element in each module of the apparatus. Uniform positioning is effected using the transferring element which includes uniformly spaced drivers, and non-uniform positioning is effected using the transferring element with non-uniformly spaced drivers. The apparatus includes a guiding element positioned adjacent to a cutting drum and has a wall closing a channel for a set of segments drawn out of a flute on the drum. The filter set is led through the channel with the aid of a dog of a chain and is advanced by a worm surface of a pushing together drum.
