pöördpainutusmasinal painutamine, mis seisneb tooriku (nt toru) järkjärgulises surumises liikumatule vormimistemplile (vrd tõmbepainutus), a method of bending in which workpiece (i.e. tube) is clamped against a stationary bend die and pressure die sweeps the workpiece around the bend die to form the bend (compare: draw bending)
