 Two flat ribbons of shell material are manufactured on the machine and brought together on a twin set of rotating dies.The dies contain recesses in the desired size and shape, which cut out the ribbons into a two-dimensional shape, and form a seal around the outside.At the same time a pump delivers a precise dose of fill material through a nozzle incorporated into a filling wedge whose tip sits between the two ribbons in between two die pockets at the point of cut out.
