flop ff5 this pressure shifts ff5 to the left and causes the pressure from manifold 170 to extend the piston rod 100 of ram c5 this action causes the clockwise rotation of plates 94 to their vertical position seen in fig3 valve v2 also applies a signal to the bottom of flip flop ff1 to return it to its original state ready for the next cycle to be initiated by valve v3 valve v5 and valve tdv5 provide an optional extra step when short ties are being sewn on the adler tipping machine the toggle switch valve v5 is manually operable in the short tie mode valve v5 is open upon the expiration of tdv1 the initial signal from flip flop ff1 is applied to time delay valve tdv5 simultaneously with the signals applied to time delay valves tdv2 and tdv3 and impulse valve imp1 the delay of time delay valve tdv5 is selected to expire shortly before the piston rod 84 of ram c6 is fully extended upon its expiration tdv5 applies a signal to the left side of flip flop ff2 to shift ff2 to the right this results in the application of pressure from manifold 170 to cause rams c1 and c2 to extend their piston rods these extensions decrease the distance between the fingers 146 of the two arms as they rotate outwardly to their furthest extension from one another this prevents the stretching of the tie when the short tie mode has been in operation the expiration of time delay valve tdv4 applies a signal to the right hand side of flip flop ff2 to cause the retraction of the piston rods of cylinders c1 and c2.
