Shrink tunnel for shrinking shrink films onto packaging or packaging units

摘要

The invention relates to a shrink tunnel (1) for shrinking a shrink film (3) onto packaging or packaging units (4) along a transport direction (TR), comprising at least one transport device (2) with a belt-like transport means (5). The belt-like transport means (5) has a transport area (5.1) for transporting the packaging or packaging units (4) along the transport direction (TR) through the shrink tunnel (1) and a return area (5.2) for returning the belt-like transport means (4) against the transport direction (TR) on. In the invention, at least one lubrication device (6) for applying a lubricant (7) evenly to the belt-like transport means (5) is particularly advantageously provided in the return area (5.2) of the belt-like transport means (5).
