in conjunction with the plastic cable 54 that the net 100 and especially the net edge cord 102 that is actually secured by hooks 60 and 62 is always under tension and taut fig7 the schematic drawing of the electrical system depicts a plurality of station finish indicator switches 86 each row of work stations 22 has its own switch 86 and each lower inspection station 41 42 and 43 each has its own switch 86 for simplicity only two switches 86 are shown in fig7 with additional switches 86 from no 2 to no 14 being depicted in phantom one lead from each switch 86 is attached directly into the relay logic controller 90 and the other lead connects into the multiple pole triple throw switch 88 the auto timer 92 is also connected directly to the switch 88 and controller 90 when switch 88 is at its number 1 position the prime mover 28 is turned off and the conveyor chains 24 cannot normally be operated when a switch 88 is moved to position 2 then the prime mover 28 can move the chains 24 when all switches 86 have been pushed or thrown after all the switches 86 have been pushed the relay logic controller 90 overrides the chain shutoff switch not shown and the prime mover 28 moves the chains 24 until the prime mover 28 is automatically shut off by the chain switch not shown when the chains 24 have moved the desired distance.
