A folding and tucker-tacker station operates upon a flat bottom end closure of a packaging sleeve, which closure comprises first and second panels opposite each other, third and fourth panels opposite each other and between the first and second panels, and a minor panel protruding from the outermost edge of the third panel. The station comprises a mounting supporting first, second and third jaws oscillatable transversely of the sleeve axis for folding inwards the first, second and third panels, and a fourth jaw displaceable along, but not transversely of, the axis for folding inwards the fourth panel. The third jaw has a recess for receiving the minor panel. The fourth jaw is disposed after the third jaw along the path of a mandrel transporting the sleeve

Packaging

An end press for bearing against a bottom end closure of a carton sleeve received upon a mandrel has recesses formed therein at locations corresponding to corner zones of the end closure, whereby those corner zones protrude outwards, relative to respective adjacent zones of the end closure, in an outward longitudinal direction of the carton sleeve.
