ABSTRACT:
A method and apparatus for the production of a stack of etched, patterned metal foils for component elements, such as fluid plates and nozzle plates, is disclosed. Individual patterned foils are cut free from a mat having a group of patterned foils and also edge foils. The patterned foils are examined and unwanted foils together with the edge foils are discarded. The approved foils are individually stacked at stacking positions in a stacking station. A number of foil stacks corresponds to the number of individual patterned foils in the mat with the patterned foils being placed on the foil stacks in correspondence with their arrangement in the mat. Additional patterned foils from additional mats are stacked onto the individual foil stacks until a counter for each of the stacks determines that a predetermined number of stacked foils has occurred. The stack is removed and a new stack is begun until the counter again arrives at the predetermined number of foils for a given stack.
