Corrugating medium is being made with increasing amounts of recycled fiber. As fiber length and freeness decline, it becomes more difficult to form flutes, particularly at high speed.
The Variable Moisture Steam (VMS™) shower supply system can help precondition the medium and improve flute formation on single facers running at high-speeds.
Operation
The VMS shower supply system works by mixing steam with a controlled amount of water to supply a saturated vapor to the steam shower. This moisture-rich steam softens and plasticizes the fibers, allowing the single facer to form proper flutes at higher speeds.
