Abstract: In an example, a clamp foot for a clamp assembly includes a housing having a distal end for engaging a workpiece, an aperture in the distal end of the housing, and a cavity in the housing extending proximally from the aperture. The clamp foot also includes a flapper in the cavity and adjacent to the distal end. The clamp foot further includes a pneumatic port in the cavity configured to direct a pneumatic force from a pneumatic source to the flapper, and a vacuum port in the cavity for coupling the cavity to a vacuum source. Responsive to the pneumatic force, the flapper is movable within the cavity to separate debris from the workpiece. The vacuum port is configured to remove from the cavity, via a vacuum force from the vacuum source, the debris separated from the workpiece by the flapper.

Abstract: A method and apparatus are presented. A first roller has a sensor that senses a speed of the workpiece while the workpiece is in contact with the first roller and moving relative to the first roller causing the first roller to rotate. The sensor senses the speed of the workpiece from a rotation of the first roller. A second roller causes the sealant on the second roller to be applied to a surface of the workpiece when the workpiece is in contact with the second roller and moving relative to the second roller. The second roller is rotationally linked to the first roller. A third roller causes the sealant on the surface of the workpiece to spread on the surface when the workpiece is in contact with the third roller and moving relative to the third roller. The third roller is rotationally linked to the second roller.
