An improved method and apparatus for making insulating wedges for use in an automatic coil placing machine which first severs the wedge material and then contemporaneously forms and slits the wedge is disclosed. The machine is adapted to provide wedges of at least two different lengths and to slit only the longer wedges. The improvement comprises a power operated punch, a forming die, and a plurality of cutting surfaces some of which are retractable wherein the punch forces the wedge blanks through the forming die and past the cutting surfaces in a single stroke. |
