When the bar feeder reaches the “BAR END” position, it activates relay K1,
lathe “COLLET CLOSING”.
With the next “COLLET OPENING”, the bar feeder receives the “FEEDING”
and “BAR CHANGE” signals”.
Relay K13 activates through the “FEEDING” signal following the “BAR END”
signal.
“BAR CHANGE-OVER” signal activates relay K19B only.
