Abstract
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
