Abstract

A loop lifter for continuous strip rolling mills has an arm which is journalled in a support for pivotal movement about a horizontal axis. An end portion of the arm carries a freely turnable roll which can engage a loop from below and lift it upwardly. A counter balancing spring reacts between a fixed pivot and the arm and assures that the pivot shaft for the arm is not subject to any free torque during pivoting movement of the arm between 0.degree. and 90.degree. of arc.
