Cigarette Filter Making Patents (Class 493/39)
  • Patent number: 10238145
    Abstract: The present disclosure relates to systems, apparatuses, and methods for assembling cartridges for aerosol delivery devices. The cartridges may be assembled by coupling a base of the cartridge to a carriage that is transported via a track. The track transports the carriages between various substations at which one or more parts are added to the base. The carriage may be lifted from the track by a lifter mechanism at each substation in order to perform assembly operations on the base. An inspection system may inspect the cartridges at various stages of completion at or between the various substations.

The rate of feed of the filter tow, the rate of rotation of the horizontal pan and the vertical wheel are controlled relative to one another such that objects are positioned at predetermined intervals along the rod. Cigarette filter elements having well controlled amounts of flavorant contained therein can be made from the rods.

  • Patent number: 8496569
    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.

  • 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.

    Abstract: Method and apparatus for producing discrete filter rods includes a first conveyor for transporting filter segments of given length in a downstream direction. Three counter rotating transfer wheels receive the filter segments between spaced apart cleats on the circumference of the wheels. The first wheel receives the filter segments from the first conveyor and transfers the segments to the second wheel which in turn transfers the segments to the third wheel. Filter segments between the cleats on the third wheel are deposited upon a second conveyor with plug wrap thereon in precisely spaced apart relationship. Granular adsorbent material is filled into cavities between the filter segments, and a garniture folds the plug wrap around the filter segments and the filled cavities therebetween.
