Abstract
A single-to-multiple line conveying system for conveying unstable articles, such as plastic bottles, having a neck ring. The unstable articles are neck ring supported and are conveyed in single file along a first path established by a first guide unit to second paths established by a plurality of second guide units through a third path established by a third guide unit having a displaceable section to align the third path with successive ones of the second paths by an electric motor actuated in response to an article counter. The unstable articles are air conveyed along the first and second paths with continuous movement of the unstable articles along the third path being effected by a continuously rotating star wheel that spaces the unstable articles and urges the unstable articles toward the displaceable section that includes a mechanical unit, having a continuously moving chain with article engaging finger units thereon, and an air unit for urging the unstable articles from the third path.
