摘要： A load having top and bottom caps is stretch wrapped at a wrapping station having turntable and a dispenser for dispensing stretch wrap packaging material, and a corner board placer for placing a corner board having tapered top and bottom edges on each corner of the load. With the load positioned on the turntable, the corner board placer is controlled by a controller to perform the steps of forming an acute angle between first and second portions of the corner board, and moving the corner board toward the corner until the first and second portions have been inserted between the top and bottom caps. The controller then causes the corner board placer to perform the steps of opening the corner board to substantially form a right angle, and simultaneously placing the first and second portions of the corner board proximate respective sides of the load by moving the corner board toward the corner in a direction oblique to the respective sides while maintaining the first and second portions generally parallel with the respective sides. A restrainer is provided for holding each corner board in place to allow subsequent corner board placement on another corner of the load. The turntable is rotated to wrap the load with the corner board placed on the corners of the load.
