Abstract: An airtight wrapper having an assembly wrapped by a wrapping sheet made of a weldable material creating a group of smoking articles obtained by: positioning the folded wrapping sheet to contact walls, front rear and head wall of the assembly, with flaps protruding beyond bottom and lateral walls; welding lower and upper flaps, and defining a transverse edge; folding the welded transverse edge rotating it by 180° toward the front wall; folding the upper and lower transverse flaps; folding the upper and lower transverse flaps; folding the rear and front longitudinal flaps, and partly also the transverse edge, toward the lower lateral walls, overlapping one on top of the other above the transverse flaps, and finally welding them to seal the airtight wrapper.

Abstract: A spacer support for packets of smoking articles includes a plurality of through housing compartments to receive at least one packet and having a pair of apertures on opposite sides for introducing or extracting the packets, and wherein the spacer support also includes a pair of lateral walls having a plurality of opposite windows, and a pair of connection walls which extend between the connecting lateral walls. A plurality of positioning elements and a plurality of access openings are disposed alternately one after the other, in succession in the longitudinal direction, so that each housing compartment is delimited by the pair of opposite lateral walls and by the positioning elements so as to stably retain the packets in a static manner relative to the longitudinal direction.

A plurality of positioning elements and a plurality of said access openings are disposed alternately one after the other, in succession in the longitudinal direction (X), so that each housing compartment is delimited by the pair of opposite lateral walls and by said positioning elements so as to stably retain inside them each of said packets in a static manner, in the longitudinal direction (X).
