HEAT SHRINKAGE APPARATUS FOR PACKAGING WITH HEAT SHRINK FILM, WITH SECTOR BURNERS.

摘要

The apparatus comprises a bridge, straddling a load transport line, on which is mounted in vertical translation a ring furnace having an opposed pair of transverse gas burners (2, 3) and a pair opposed side gas burners (4,5), perpendicular to the other pair, each able to expel hot air from a peripheral zone to a central working area of said oven in which a load to be packaged must a stay, at least one of said transverse burners (3) being mounted in horizontal translation along an axis of advance / distance relative to the other of the transverse burners (2), and at least said lateral burners ( 4, 5) are longitudinally divided into at least two energy independent sections (4a, 4b; 5a, 5b) for the formation of independently adjustable hot air streams.
