SHRINK TUNNEL FOR SHRINKING SHRINK FILMS ONTO PACKAGES OR PACKAGING UNITS

摘要

The invention relates to a shrink tunnel (1) for shrinking a shrink film (3) onto packages or packaging units (4) in a transport direction (TR), comprising at least one transport device (2) having a belt-like transport means (5). The belt-like transport means (5) has a transport region (5.1) for transporting the packages or packaging units (4) through the shrink tunnel (1) in the transport direction (TR) and a return area (5.2) for returning the belt-like transport means (4) counter to the transport direction (TR). Particularly advantageously for this invention, at least one lubricating apparatus (6) for uniformly applying a lubricant (7) to the belt-like transport means (5) is provided in the return area (5.2) of the belt-like transport means (5).
