Abstract
An apparatus for shrinking film onto products moving along a conveyance path includes an elongated steam chamber shaped to form a shrink tunnel through which the conveyance path extends, wherein tunnel side surface portions of the elongated steam chamber bound the path at least in tunnel regions above a plane of the conveyance path and the tunnel side surface portions are heated by steam within the elongated steam chamber and the tunnel side surface portions thereby radiate heat into the shrink tunnel. At least one steam header is positioned within the shrink tunnel and extending along at least part of a length of the shrink tunnel, the steam header including a plurality of steam ejection orifices for ejecting steam into the shrink tunnel. At least one steam flow path feeds steam from an output of the elongated steam chamber to an input of the at least one steam header.
