wherein a side panel is hingedly connected to said top side panel and to said bottom side panel of said carton blank;
wherein said raising opens said knock-down blank so that said side panel is brought into abutment with a generally vertically extending back wall of said shuttle;
and wherein said method further comprises:
(d) after said raising, gripping said side panel of said knock-down carton blank with a gripper of said back wall;
