Abstract
Articles of random length are conveyed in single file while being transferred from a first driven conveyor to a second driven conveyor. The second conveyor is driven faster than the first conveyor so that an initial gap is established between the articles. Front and rear ends of the articles are sensed while traveling along the second conveyor toward a third conveyor. From that sensed information, there is determined an actual front-to-front distance between the front end of each article to the front end of the next article. The speed of the second conveyor is varied, as necessary, to create a desired minimum front-to-front distance between successive articles. Optionally, that minimum front-to-front distance is established while ensuring that a minimum gap is maintained between successive articles.
