ABSTRACT:
This invention relates to an air conveyor for conveying articles with a collar and a head arranged above that, in particular plastic bottles along a conveyor channel having two carrying strips arranged along the conveyor channel on which the articles are conveyed by suspending them from the collars, and having a head space having inclined side walls formed above the carrying strips. Air nozzles, which act upon the heads of the articles, are provided in the inclined side walls. This counteracts a tendency of the articles to become tilted or jammed together.
