ABSTRACT:
A method and apparatus for cutting and forming planar strip material which is particularly useful in the fully automatic, high volume production of precision, microminiature multifid electronic brushes. With the apparatus of the invention, high quality electronic brushes are produced automatically from a continuous thin strip of metal or metal alloy. At predetermined locations along the length of the strip, the material is cut so as to form a multiplicity of precisely spaced apart longitudinally extending slits or incisions. The material is then automatically cut transversely of the slits so as to form a multiplicity of precisely spaced apart outwardly extending fingers. The fingers are then formed in a forming die to the cross-sectional configuration desired for end product use.
