  • a perforation 25 passes over the upper end portion 122 of the housing 120, there is no reflection of the light to the photocell P1.
  • This sequence of actuation of the photocell P1 produces signals which are amplified by an amplifier A1 to energize a preset counter 125 FIGS. l and 5).
  • the output signal from the amplifier A1 triggers a transistor TR1 which energizes a relay K1 connected to the transistor TR1 through a manual control switch S3.

  • a perforation 25 within a packet 20 passes over the photocell P1
  • the voltage applied to relay K1 drops to a level which deenergizes relay K1 so that its normally closed contacts 2K1 will close causing the capacitor C3, which was charged to a level of 15 volts, to energize a relay K2.
  • Normally open contacts 1K2 of relay K2 are closed thereby energizing relays K3, K4 and K5.
  • the normally open contacts 1K4 of relay K4 hold the relays K3, K4 and K5 in an energized condition.
  • Energizing relay K3 opens the normally closed contacts 2K3 thereby opening the line to the brake solenoid BR so that the output shaft 65 is free to rotate. Simultaneous energizing of relay K5 causes the normally open contact 1K5 to close and the normally closed contacts 2K5 to open thereby supplying two voltages to the clutch solenoid CL.
  • the first voltage is at a level of 35 volts DC and is supplied from a capacitor C4 which is charged when contacts 2K5 were closed. This high voltage produces rapid acceleration of the clutch 58 so that each wire binding section 80 is quickly fed into engagement with the packet 20 being fed over the photocell P1.
  • the clutch solenoid CL is energized, the binding strips 80 start to feed and the charge on the capacitor C4 drops to its normal supply voltage of 7 volts.

Each count registers on the counter 125, and after a present count is reached, a relay K6 is energized by the counter 125. When normally closed contacts 2K6 open, the relays K2, K3, K4 and K5 are deenergized thereby opening the circuit to the clutch solenoid CL by opening contacts 1K5 and energizing brake solenoid BR through its normally closed contacts 2K3. Capacitor C5 provides an initial high voltage of 35 volts to the brake solenoid BR to effect quick actuation of the brake 60 after which the voltage to the brake solenoid BR drops to its normal level of 7 volts.
  • relay K6 When relay K6 is energized, its normally open contacts 1K6 close to energize a relay K7, thereby closing normally open contacts 1K7 to energize a solenoid air valve CAV for actuating the cutoff air cylinder 78 which, as mentioned above, cuts the wire binding strip 30 into the sections 80 having a predetermined number of looped prongs 40.
  • a manual control switch. S4 is arranged in parallel with contacts 1K6, and a manually operated reset switch RS provides for resetting the counter 125.
  • Diodes D1 and D2 serve to isolate the higher voltage power in line L4 from the lower voltage power in line L3, and diodes D3 and D4 serve to dissipate the energy in the brake coil BR and the clutch coil CL when they are deenergizedl l
