Abstract: A continuous rolling mill with crossed alternately inclined stands is described in which the working rolls and their roll chocks forming each stand are united to form a unit which can be displaced individually in a direction parallel to the axes of rotation of the said rolls. During changing of the rolls, a thrust member expels the said unit from the stand, in a direction parallel to the axes of rotation of the rolls, onto a load-carrying platform which can be tipped about an axis parallel to the rolling direction to a horizontal position on a carriage which is movable on rails along the sides of the rolling mill.

Abstract: Successive coils of strip are fed to an unwinding station by a transfer carriage supporting at least two driven coil support rollers on a vertically movable coil support, support for a tight or slack coil during a preliminary unwinding being provided by retractable arms carrying idler rollers for rotatably supporting a coil, the arms when extended supporting the idler rollers between the driven rollers. A further pair of retractable arms at the unwinding station support further idler rollers which when extended are located at the same height as idler rollers of the first retractable arms, with one of the driven rollers being located between two of the idler rollers so that, upon lowering the carriage-mounted support the coil originally supported by the driven rollers is caused to rotate onto the idler rollers and is thus transferred from the driven rollers to the idler rollers.
