Abstract:
1. A cluster arm arrangement for an intermediate roll set of an 18 HS roll stand where between a chock at an operating side and a chock at the drive side there are respective cluster arms that are pivotable laterally of an intermediate roll and in which are integrated lateral backing rolls for support of working rolls in the stand the cluster arm arrangement comprising: a respective pivot pin that is between each chock and the respective cluster arm, that is fixedly connected with the respective cluster arm, and that defines an axis about which the respective cluster arm is pivotable; respective locking bars pivotal inward on the chocks for axially arresting the respective cluster arms relative to the respective chock while permitting the respective cluster arms to pivot about the respective pivot pins, and respective abutments and restoring springs operatively connected to each of the pivot pins as a compact unit in a region between the respective cluster arm and chock for limiting pivoting of the respective cluster arm, the abutments being fixed on outer collars of the respective pivot pins and braced outwardly against the locking bars for limiting pivoting of the respective cluster arms.
