An improved machine for wrapping continuously moving articles with heat-shrinkable material comprising a series of at least three horizontally aligned coplanar longitudinally spaced conveyors provided with a monodirectional continuous movement and with the adjacent sections of the two conveyors furthest downstream wound on at least a corresponding pair of return rollers supported by a support carriage which may be moved in an alternate manner parallel to the conveyor direction, means for supplying sheets of wrapping material and a pair of winding bar means caused by conveyor means to move continuously around the article being supplied on the intermediate conveyor such that during each rotation, while one of the bars takes a sheet of wrapping material and brings it across the path of a following continuously moving article so as to wind this material about three faces of this article, the other bar winds the material about the fourth face of the preceding article and, by means of the two adjacent conveyors furthest downstream, superimposes the final flap on the flap which has already been folded over the lower face of the said preceding article.
