Abstract
A method and apparatus for wrapping selected articles of a plurality of articles. A stream of the articles is moved along a first path by a first conveyor. Selected articles are sequentially moved from the stream of articles moving along the first path to a second conveyor by a deflector. Moving the selected articles from the stream of articles results in the forming of gaps in the stream of articles at locations where the selected articles are sequentially moved from the stream of articles. The gaps in the stream of articles are maintained as the stream of articles moves along the first path. Disposed along the second path is a wrapping station where selected articles are sequentially wrapped. As one of the selected articles is moved through the wrapping station, a pair of webs engage opposite sides of the one article and are sealed to wrap the one article. The seal is severed along its center portion and adjacent to a trailing end of the one article. The next selected article engages the remaining portion of the severed seal and pulls the webs forward to enclose the next article as it is moved along the second path. The second conveyor moves the wrapped articles back to the gaps maintained within the stream of articles moving along the first path by the first conveyor.
