loading then for each cycle of operation an operator simultaneously presses palm switches 38 and 134 while the pnuematic cylinder advances the case 42 limit switch 62 is contacted by the trip bar 66 causing cylinder 70 to advance the stop plate 68 as the distal end of the case 42 contacts the stop plate 68 the trip bar 66 contacts the third limit switch 64 when the third limit switch 64 is contacted the cylinder 82 extends lowering the needle platen sub assembly 80 causing the needles to pierce the cartons 43 at the end of extension of cylinder 82 the fourth limit switch 118 contacts the upper surface of the stripper plate 106 causing the pneumatic controller to allow pressurized air to flow through needles 136 to begin thereafter air is blown through the short needles 136 into the cartons 43 to force the juice out through the long needles 138 the juice flows through the collect lines 133 to the collection manifold 130 and out the exhaust pipe 132 the air supply step is maintained for a preset period e g 15 20 sec generally sufficient to fully exhaust the juice from the cartons 43 thereafter each of the cylinders automatically simultaneously and completely retract cylinder 82 retracts until the fifth limit switch contacts the under surface of cylinder support plate 88 simultaneously forwarding cylinder 44 retracts until the trip bar 66 contacts the first limit switch 60 if the controller 36 has.
