AbstractA singulator apparatus includes a forwardly driving device and a reverse driving mechanism which operate together to separate individual articles from a stack of articles being transported thereto from an upstream feeding device. The singulator further includes a sensor which detects the presence of articles at the articles ingestion nip defined between the forwardly driving device and the reverse driving mechanism. A controller stops operation of the feeding device upon detection of the presence of articles by the sensor and initiate feeding by the feeding device if no articles are sensed by the sensor.
