ABSTRACT:
A machine for packing articles supplied in a uniformly spaced manner by means of a continuously moving conveyor with a web which is progressively cut from a roll of heat-shrinkable material and projects from two lateral faces of the articles and brought in sequence by suction feed means along the respective longitudinal edges across the feed path between individual successive articles so as to be folded over the front, upper, lower and rear faces of a corresponding article with a trailing end portion extending beyond the respective lower face. The conveyor comprises two adjacent conveyor belt sections with the web feeder means supported in the area of the zone lying between the two adjacent conveyor belt sections. The adjacent zones of the two belts are wound on at least one pair of corresponding return rollers supported by a carriage which may be moved in an alternating manner parallel to the direction of transport and the feeder means may be moved in an alternating manner vertically and parallel with respect to the movement of the carriage.
