Abstract: In apparatuses and methods for treating a plate-shaped process item including a bottom side, a top side and edges between the bottom side and the top side with a process medium, a transport unit is used, which includes an endless unit with support elements projecting from the same. A bottom side of the plate-shaped process item is supported on support elements of the transport unit and the transport unit is driven to move the support elements together with the supported plate-shaped process item in parallel to a process media level of a process medium. In a first operating mode, during a movement of the plate-shaped process item in parallel to the process media level, no parts of the transport unit engage the edges of the plate-shaped process item.

Abstract: A device for processing a process good with a process medium has a provider for providing the process medium, and a transporter. The transporter has a transport element configured to move the process good along a process path between being accepted by a delivery device and being delivered to an accepting device and move with the process good from being accepted to being delivered. The process good enters the process medium laterally and is moved through same or is passed by same while floating on the process medium.
