Abstract
A device for grinding longitudinal welds in a steel door or the like is provided. The device includes a bed for receiving the door and means for moving the door along the bed on a path between opposed grinding wheels. One of the grinding wheels is fixed and the other is mounted to a carriage designed to move transversely to the bed. Switches actuated by the door activate the grinding wheels and moving means. The carriage includes means to limit its movement to insure a proper engagement with the door and the grinding wheels are set at an angle with respect to the axis of the bed to further insure proper contact.
