Abstract: A housing structure for a rolling mill stand has two housings spaced apart and secured together with a spacer structure clamped between them by replaceable bolts. The housings support horizontal rolls and optionally vertical rolls and these rolls are supported on the spacer structure when the housings are displaced away from each other and from the spacer structure.

Abstract: A transporter car for carrying a metal coil comprises a wheeled trolley with first and second supports for engaging the periphery of a coil to provide supports for the coil. The supports are arranged in side-by-side relation in the direction of movement of the trolley and one of the supports is retractable so that it can be used in combination with the other support for long coils and the other support is used on its own for short coils.

Abstract: A rod treatment line consists of a rod conveyor on which the rod is carried in open loop form, a coil forming device for forming the rod into coils, and a coil loader for moving the coils from the coil forming device to a loading station with the axes of the coils horizontal. For removing the coils there is a conveying system consisting of a number of hooks suspended from a track, the hooks being aligned with the track and pointed in the direction opposite to the direction of movement. In order to bring the hooks to the loading station pointed towards the coil forming device, so as to facilitate loading, the track is routed in its approach to the loading station, to pass the coil forming device from the direction of the rod conveyor.
