A buffer belt on which potted plants are collected is realized for this customer. A buffer strip is applied to large numbers of pots to collect and ensure the discharge process proceeds undisturbed. The pots are buffered efficiently so that they can be moved quickly and easily by, for example, a pot fork or fork-lift truck with chain fork. A buffer belt is available in different sizes and can be equipped with an expander and / or an outfeed belt. A buffer belt in combination with an expander ensures that the pots are collected on a pre-collection belt. After the set number of pots is reached, they are transferred to the buffer belt. The buffer belt then slides through a row. Various programs can be easily set and saved using the touchscreen.
