Abstract: A produce labeller has first and, optionally, second selectively actuable label supply cartridge for selectively supplying labels from the fast or second selectively actuable label supply cartridge to corresponding fast and second label transfer positions in a fast plane. A rotatable label transfer piston housing is provided, rotatable in the first plane on a drive shaft. The rotatable label transfer piston housing has mounted radially therein in the fast plane radially spaced apart resiliently biased radially telescoping label transfer pistons for picking up labels from the fast or second selectively actuable label supply cartridge at the fast or second label transfer position, and rotationally carrying the labels from the first or second label transfer position to a label deposit point. The labels are carried on exposed ends of the radially spaced apart resiliently biased radially telescoping label transfer pistons, one label per exposed end, by selectively actuable vacuum apertures on each exposed end.
