Definitions

  • the operating plate 2'l is now moved into position beneath the pick-up head 3i and the head is then lowered on to the disc whereby the vertical extending pins 21a engage with and are received in the openings 45 formed in the plate 44.
  • the control valve is then momentarily operated to allow communication between the pick-up head and the pressure line or a line communicating with the atmosphere and upon thus releasing the vacuum the washers fall into position upon the disc I in locations immediately surrounding the pins 210..
  • the pick-up head is again raised to the position illustrated in Fig. 6.
