The invention relates to a poster hanging bar for reinforcement of the edge of items such as posters, which are to be suspended on a wall or from a ceiling. A bar is used, which can be made of a metallic material, for the edge reinforcement and the bar is pressed around the edge of the poster. The bar is fastened to the poster either by clamping of end points, which are situated after angular shapes on the bar, or by the bar being exposed to point by point deformations and an angular shape, which gives the edge reinforcement bar a distinctive mechanical strength. The edge reinforcement process can be automated, whereby the demands for manual labor are minimized. The components are inexpensive, readily available and the finished edge reinforcement is highly robust and durable.
