Shrinking device for heat shrinking of film around article or article combination, has movable cover bar assigned to nozzle area of shaft wall with certain length, where length of cover bar corresponds to former length

摘要

The shrinking device has a movable cover bar (20) assigned to a nozzle area (6) of a shaft wall (3) with a certain length, where the length of the cover bar corresponds to the former length. The cover bar is associated to an upper edge of the shaft wall in a working position (AP1) and the cover bar is brought into another working position by a vertical movement (BV). The cover bar is upstream and spaced to the nozzle row (8') in the latter working position, so that the flow direction of a shrinking medium (7) flowing in an inner chamber (2') of a shaft (2) is deflected in the nozzle area. An independent claim is included for a method for heat shrinking of a film around an article or article combination in a shrinking device.
