  • Page 17: Functional Characteristics

    14 FUNCTIONAL CHARACTERISTICS Idle position Because of the connection of the tool to the compressed air-net (connection P) compressed air flows through flapper valve 3 to the flapper cylinder 19 and rocker cylinder 17. As a result of this air-flow, the closing force of the spring of the flapper cylinder 19 is supported by compressed air on the one hand (flapper closed) and the feed-wheel is lowered to the gripper on the other hand.

  • Page 18: Adjustments

    As soon as the upper strap is sheared off, the sealing valve lever 25 can be released. Sealing valve 5 switches to deaeration, the compressed air in cylinder 20 starts to flow back and escapes through the pressure reduction valve 15 (back stroke area), sealing valve 5 and the lower part of the cylinder 20 into the athmosphere.
