Abstract
A sheet transport array for advancing sheets along a track at a desired speed past a process station. A sheet speed measuring device is coupled to the process station. A drive roller assembly includes at least a drive roller and a drive idler, with the drive roller driving the advancing sheet at the desired speed toward the process station. A second roller assembly includes at least a second roller and a second idler, with the second idler moving at the speed of the advancing sheet. A floating roller assembly includes at least a floating roller and a floating idler. The floating idler is coupled to the second idler to move at the same speed as the second idler and the advancing sheet. The floating roller and the floating idler define a pinch point with a pinch force such that the floating roller and the floating idler move at the same speed. The floating roller is coupled to the speed measuring device so that the speed measuring device measures the speed of the advancing sheet prior to the advancing sheet making contact with the floating roller assembly.
