Corrugated board manufacturing apparatus including a preheater section with a variable heat transfer system and a hotplate section with a passive hold-down mechanisim

摘要: A variable heat transfer system and a passive, segmented hold-down mechanism for preheater section hotplate of machine manufacturing corrugated board. The assembly having the includes plurality actuators to urge continuous web material toward drum. sacrificial is positioned between on drum actuators. In response moisture detection in by sensors, one or more applies pressure cross-machine direction wet portion material. Also, independently weighted feet varying profile formed upon compensates variations contour surface section.
