The present invention relates to a method for bundle-packaging batches of products, wherein products are moved in a longitudinal running direction, grouped into batches and wrapped with a film of heat-shrinkable film. Each wrapped batch is heated to form a contraction of each sheet around said batch. Heating of a batch is performed by the circulation of at least one heated air stream and by the expulsion of said stream toward the interior of the enclosure of an oven provided, successively, with first and second sections; the sheet is cooled; during heating, along at least a part of the first section, a first air stream is shaped discontinuously and expelled toward the interior of said enclosure. The method consists, during heating, along said second section, in shaping a second stream as an air knife and expelling said air knife toward said sheet to be smoothed.

Method for bundle-packaging batches of products, heating device and facility with such a device

A device for heating wrapped batches of products and a packaging installation provided with such a heating device, specifically having a manifold of heating elements with lines of orifices and a blocking device for the orifices using a mobile plate having for each line of orifices openings, at least two successive openings having different lengths, to go the direction of movement a) from a position blocking at least a first line of orifices and opening at least a second line of orifices, b) to another position opening the first line of orifices whilst maintaining open the second line of orifices.
