Multi Function Buffer

Multi Function Buffer

This unit allows buffering of PCB's in FIFO, LIFO, Pass-throughmode. It uses belt segments to hold the PCB over its complete lenght. When adding or extracting a PCB to/from the buffer a drive mechanism engages with the belt segment to smoothly transfer the PCB in or out.
