Abstract
An apparatus for shrinking heat-shrinkable sleeves around containers or the like includes at least two diffuser housings mounted respectively adjacent side edges of a conveyor on which containers or other objects having a sleeve thereon are to pass. A cap which defines a tunnel is positioned between the two diffuser housings over the conveyor. Each diffuser housing is provided with a longitudinally extending slot presenting directional discontinuity at its two end portions. The two end portions of each slot may be horizontal, while the control portion of each slot is sloped in a vertical direction and extends from one end portion of the slot to the other. Provision is made to feed hot air through the slots into a tunnel so as to contact the films on the containers or objects moved by the conveyor.

An apparatus for shrinking heat-shrinkable sleeves around containers or the like comprising a conveyor on which containers having heat-shrinkage sleeves thereon are to be moved;
- at least two diffuser housings, respective ones of said diffuser housings being positioned adjacent respective side edges of said conveyor and defining therebetween a heating station;
- at least one lengthwise slot for distributing hot air into said heating station extending along each said diffuser housing, said slot having a central portion having an inclination with respect to vertical and presenting vertical directional discontinuity along its two opposite end portions, said end portions having respective inclinations with respect to vertical different from the inclination of said central portion;
- and means for feeding hot air to said diffuser housings.
