1. A device for crimping edges of metal sheets by folding one of said edges onto another one of said edges, comprising:
a support member;
an intermediate support member pivotably mounted on the support member to pivot about an axle extending generally transversely to the support member,
a blade holder carrying at least one crimping blade, the blade holder being mounted to the intermediate support member so as to be translatable along the intermediate support member;
a pivot cylinder operably connected to said intermediate support member to pivot said intermediate support member relative to said support member about said axle when activated, whereby the intermediate support member is pivotable between a low position and a tilted high position: and
an actuator comprising a cylinder linked to the blade holder and a sliding rod comprising a rounded distal end facing the crimping blade, said sliding rod being movable in a direction generally perpendicular to said axle, said rounded distal end configured to engage with a bearing part on a die for receiving the metal sheet edges.
