Abstract

Abstract A series of ferromagnetic articles to be turned 90* are moved by an inclined conveyor along a linear path over a deadplate and between two turning drums having resilient peripheral surfaces shaped to conform to the curvature of the contacted surfaces of the articles being turned. One of the drums is driven at a higher speed than the other drum and has its axis of rotation disposed forwardly of a plane which is perpendicular to the linear path and has the axis of rotation of the other drum lying therein thereby providing an angular space or gap between one end of the article being turned and the next following article so that the resilient material on the high-speed drum will enter the space. The discharge edge of the deadplate is angled so as to be parallel to the partially turned articles causing both ends of each article to move off the deadplate onto the conveyor at the same time. A magnetic stabilizing conveyor is positioned to grip one end of each article as the article completes its turn.
