The hinge has a pin (12) which connects its two parts together. It has, at one end, a ring bead which forms a stop (13) which restricts insertion into rolling zones (9,10,11) or sleeves of the hinge flaps (3,4). The other hinge flap (15) can be fitted by a rolling zone (14) or sleeve onto a part of the hinge pin projecting beyond the stop. The hinge parts can be made of sheet meal or a zinc casting. |
