In the erection of a tray having edge flaps with end flaps which are to be fastened together for forming a rim of edge flaps intended for receiving a lid, the erection is performed in two separate tools. In the first tool only the one pair of opposing edge flaps are folded out, whereafter their end flaps are folded up and attached to the outside of the second pair of end flaps. The partially erected tray is then ejected from the underside of the forming chamber and transferred to a second tool where all edge flaps are subjected to being folded downwards. |
