Abstract
The charcoal wheel is provided with pnuematic means for forcing the pistons outwardly to dispense charcoal and a second pneumatic means for the retraction of the pistons. The pneumatic ejection of the pistons permits a high speed output, for example 6000 inserts per minute i.e. more than twice the output of current state of the art machines. Each piston is made in one piece with an integral stop to limit the outward movement and the inward movement of the piston.
