Definitions

  • flat goods also includes layers of bars, profiles or narrow bars or stacks of baskets which are filled with bulk goods or small good parts.
  • reversing flaps are particularly problematic when they have to be used in larger heat treatment systems with higher temperatures. In these cases, the reversing flaps can warp and jam, which leads to frequent malfunctions or even business interruptions.
