A process for producing structures includes: cutting a transverse groove in a panel; introducing a plastic material into the groove; applying an imprint to the panel; cutting V-shaped grooves in the panel and folding the panel to form a structure. The plastic material is initially free-flowing and subsequently solidifying. The plastic material forms a hinge which may be flush with the panel or project beyond the panel.
