Multiple Rotor Patents (Class 19/87)
  • Patent number: 4971540
    Abstract: An apparatus for laying a mat of fibrous material which includes an upwardly inclined belt onto which the fibrous material is fed, one or more combing roller located above the belt, a stripping roller at the upper end of the belt for removing the material from the belt and passing it into a mechanism for laying the material into a mat. The angle of inclination of the incline belt and the position of the first combing roller as such that the material can build up to reach a critical angle of repose and then slide back down. A second combing roller located upstream of the first combing roller serves to comb the material to a constant depth, and the speed of the incline belt is adjustable to determine the amount of material leaving the incline belt and thus regulate the thickness of the formed mat.

  • Patent number: 4338705
    Abstract: The present disclosure relates to a method and apparatus for separating trash from irregularly-shaped clusters of material containing trash, fiber motes, and cotton lint. The apparatus comprises a rotatable drum encircled by a screen. The drum contains a plurality of finger-shaped baffles preferably arranged in two rows disposed 180.degree. apart on the inner periphery of the drum. As material is delivered to the rotating drum, the finger-shaped baffles lift and tumble the clusters of material and pull the material apart to separate the heavy trash. The heavy trash drops through the screen and is removed by a conveyor. The fiber motes and cotton lint, along with smaller trash, are retained within the rotating drum and removed at an outlet end of the drum.
