  • Patent number: 5875824
    Abstract: A method and apparatus for delivering predetermined amounts of material, the apparatus comprising a chute; a metering wheel in cooperative relation to the chute to repetitively draw discrete amount of material onto the metering wheel; an arrangement for establishing a procession of spaced apart articles along a path, a transfer wheel for repetitively transferring discrete amount of material from said metering wheel to spaces defined between adjacent pairs of articles in the procession and a cleaning wheel for removing extraneous material from the articles.

  • Patent number: 5542901
    Abstract: This invention relates to a method for delivering free-flowing material into discrete receiving spaces separating filter plugs in partially constructed cigarette filter assemblies. The method includes rapidly feeding a free-flowing material such as charcoal into partially constructed cigarette filter assemblies. The free-flowing material is dispensed to a first conveyance and is subsequently transferred to a second conveyance that is positioned parallel and above the first conveyance. Vacuum is used to hold the free-flowing particulate material onto the first conveyance and is used to transfer the free-flowing material to the second conveyance and to hold it there. The free-flowing material is next transferred onto receiving spaces formed between articles such as cigarette filter plugs that are disposed on a third conveyance. The transfer of the free-flowing material to the receiving spaces and retention is also facilitated by application of vacuum.

The method entails rapidly feeding a free flowing material such as charcoal into partially constructed cigarette filter assemblies. The free flowing material is dispensed to a first conveyance means and is subsequently transferred to a second conveyance means that is positioned parallel and above the first conveyance means. Vacuum is used to hold the free flowing particulate material onto the first conveyance means and is used to transfer the free flowing material to the second conveyance means and to hold it there. The free flowing material is next transferred into receiving spaces formed between articles such as cigarette filter plugs that are disposed on a third conveyance means. The transfer of the free flowing material to the receiving spaces may also be accomplished by use of vacuum or gravity.

  • Patent number: 5221247
    Abstract: This invention relates to a device for delivering free-flowing material into discrete receiving spaces separating filter plugs in partially constructed cigarette filter assemblies. The device has a metering drum for dispensing free-flowing material onto an air permeable transport tape. A vacuum source beneath the transport tape retains the free-flowing material on the transport tape which conveys the free-flowing material beneath a set of pockets mounted on or within a moving belt. Each pocket is divided by a screen permeable to air but not to the free-flowing material. As the transport tape moves beneath the pockets, vacuum applied beneath the tape ceases, and vacuum applied to the pockets draws the free-flowing material up into the pockets, and retains the free-flowing material in the pockets. When the belt transfers the pockets out from under the vacuum hood, and the vacuum is no longer applied, the free-flowing material is released from the pockets.

  • Patent number: 5199447
    Abstract: This invention relates to two parallel belts with pockets suspended between them. This pockets device is used in a machine which delivers free flowing material into receiving spaces separating filter plugs, as said plugs travel on a garniture tape. The pockets include channels or funnels through which free flowing material can flow. The belts carry the pockets in part parallel with and adjacent to the garniture tape carrying the filter plugs. The belts and the garniture tape are synchronized so that receiving spaces between the plugs precisely register with the funnels in the pockets. Such precise registry insures that the charcoal chute delivers free flowing material through the funnels into the receiving spaces.

  • Patent number: 5176606
    Abstract: This invention relates to a laminated belt for use in a machine which delivers free flowing material into receiving spaces in between filter plugs. The belt of this invention is a lamination of a metal band and a composition strap perforated with a plurality of apertures. This belt travels in part parallel with and adjacent to a garniture tape carrying filter plugs separated by receiving spaces. The composition strap is shaped to conform to the round shape of the filter plugs, and it contacts the filter plugs, urging them against the garniture tape. The belt and the garniture tape are synchronized so that the receiving spaces precisely register with the apertures in the belt, while an independent device delivers free flowing material through the apertures into the receiving spaces. By urging the filter plugs against the garniture tape, the belt holds the filter plugs in this registered position on the garniture tape.
