Method for binding a bundle of leaves (11) in a binding element (1) with a U-shaped back (2) with a base (3) and upright arms (4) and a hot-melt adhesive (8) in the back, and this method consists of introducing the bundle in the back (2), and then heating up the back (2) to melt the hot- melt adhesive (8), characterised in that an oversized binding element (1) is chosen in which the bundle (11) is received with a certain sideways play (C), and that the binding element (1) with the hot-melt adhesive (8) in the molten state is placed between two parallel pressure bars (17) that are moved towards one another with a force in order to fold the arms (4) towards one another. |
