    Abstract: A conveyor system for transporting elongate articles along a conveying surface to a workstation. The conveying surface forms an endless path having an upper conveying path and a lower return path. The conveying surface has article holders fixedly connected on the conveying surface for holding the elongated articles on the conveying surface with longitudinally extending sides of the article essentially extending outwardly from the conveying surface. A gripping device is positioned adjacent the conveying surface and pivots about an axis for unloading and loading the article to and from the conveying surface in a single pivotal motion. A first article holder type includes a pair of arcuate portions positioned to form a discontinuous cylindrical configuration having open areas between each end of the arcuate portions and an upper lip for receiving a complementary groove in the elongate article.
