The method relates to the field of shrinking sleeves of shrinkable plastic (PVC or the like) around objects while the latter, surrounded by their loose sleeve, circulate in a heat-shrinking device (for example a tunnel). According to the invention, at the same time as hot air for shrinking is supplied, a gaseous fluid, for example air, whose temperature is lower than the softening temperature of the sleeve is blown between the object 1 and the sleeve 3. This injection of gas is, for example, made above 8 and below 9 the object as it is being transported on the conveyor 2 into the heating tunnel 4. <IMAGE>
