Tightening arrangement for paperboard wrap and tightening section for apparatus for applying a wrap around a plurality of articles

A paperboard wrap comprising series of panels hingedly connected together along a fold line and at least one tightening arrangement, including a first cut formed in a first panel, which first cut has two ends located along a hinge line to define a first part, and a second cut formed in a second panel, which second cut has two ends located along the hinge line to define a tab part which is integrally formed with the first part to constitute a hinge panel, at least one of the ends of the second cut being disposed generally between the ends of the first cut, whereby in use the hinge panel is pivoted along the hinge line, with parts of the hinge line between adjacent ends of the cuts providing surfaces for engagement by a tightening edge of a packing machine, and wherein the second panel comprises a base wall of the sleeve, with another base wall of the sleeve forming a panel similar to the second panel.
