Leveling is used to influence the thickness wedge, whereas work-roll bending and shifting affects the strips thickness profile. However, for strip that is not under tension, changing the leveling of the work rolls determines whether or not there is camber build-up.
Before concrete is hardened, the reinforcing steel is pulled or put in tension by jacks at the sides or ends of the concrete form. When the concrete hardens, the stretch of the steel is in tension while the concrete is in compression. Press Brake A machine used in cold-forming metal sheet or strip
