A corner lap folder for a cardboard tray consists of a lever, whose resistance arm 1 is angular and rotates about a shaft 2 while the power arm 3 is pivoted (4) to the rod 5 of a cylinder 6. It is all supported by a base 7. A folder is provided at each corner for the simultaneous folding of the four laps onto corner reinforcements 12 (13, Fig 5, not shown) to which they are glued. <IMAGE> |
