A conveying system is disclosed for conveying unstable articles having a neck ring. Unstable articles, such as plastic bottles having a neck ring, or flange, are conveyed in single file along plural paths each of which is established by dual guides vertically spaced from one another a distance just sufficient to receive the neck rings of the articles therebetween, with the articles being urged in the downstream direction along each path by air acting solely on the top portion of the articles above the neck rings. A combiner unit controls single filing of articles conveyed along the plural paths to a discharge conveyor through use of star wheel actuators, the arms of a first group of which are moved in the downstream direction along the plural paths with the arms being configured to engage the neck rings of articles then on the plural paths and thereafter control movement of the articles in conjunction with a second group of star wheel actuators, the arms of which are also moved in the downstream direction along the plural paths.
