Abstract:
1. A window processing system for use in fabricating window frames or sashes comprising: a) a cleaning station comprising one or more cleaning tools that are actuated to move into contact with selected portions of a window frame or sash; b) one or more non-contact sensors for determining an unknown profile of the window frame or sash; and c) a programmable controller coupled to the one or more cleaning tools to control movement of said cleaning tools and also coupled to the one or more non-contact sensors for monitoring an output from the non-contact sensors to determine a sensed profile indicating irregularities occurring during fabrication of the frame or sash or dimensional variations differing from a nominal frame or sash size and then, during a cleaning compensation stage, adjusting movement of the one or more cleaning tools to clean specified one or more locations of the window frame or sash based on the sensed profile of the window frame or sash.
