The invention relates to rolling mills for processing J-metals and is particularly suitable for «« alz ^ erke with successive scaffolds, in which the 7 / alzspalte at different angles lie to each other. In the case of rolling mills for various types of products, it should be possible to adjust the location to be able to adjust one or more scaffolding in order to adapt the .. · alzv / Erkstraße to the one to be processed To adapt the product.

Axes can be pivoted, the planes of movement of these two axes being perpendicular to one another stand.

The pivot axes of the pulley bracket can be arranged so that the plane in which the first pivot axis and a pass line of the rollers is perpendicular to the plane in which the second pivot axis and the pass line of the rollers lie, so that if the bracket structure is tilted if the planes pivot by an angle of 90 °, the pass line of the rollers assumes the same spatial position as before such an adjustment. The support structure of the rollers 4c can also accommodate the means for driving the rollers.

The frame 115 is pivotable about two parallel axes, which are shown in J ¹ Ig. 5 are indicated by dash-dotted lines 126 and 127. The bearing axis 126 is determined by bearing journals 128 and the axis 127 by axle bearings 129. The bearing journals 128 are seated in bearings 130 which are slidably guided in vertically extending recesses or grooves 132 in frame parts 133 (see FIG. 7) which are located on the front and rear of the frame. Wheels 134 are seated on the axle bolts 129 and run on rails 135 which are made in one piece with the frame parts 133.

The frame parts 133 are arranged so that their recesses or Mutes 132 face each other with their open sides, and the vertical axes of the ITuts lie in a common plane that is perpendicular to the plane of the surface of the rails I35.

Through the in S'ig. Point 147 shown in 6 runs the middle pass line of the rollers perpendicular to the plane of the drawing. The dash-dotted line 144 indicates a plane

Because of this arrangement, when the scaffold is tilted so that the Planes pass through an angle of 90 °, the same ' spatial position in which he is in front of such a Adjustment is located. This is best seen in FIG. 8 in which the scaffolding is in the vertical position schematically in solid lines and in-horizontal * Position is indicated with dash-dotted lines.

The bearings 130 have vertically extending pins IJl., Which corresponds to the representation in]? Ig. 5 and 6 pass through openings in portions 136 of the faucet parts and have eyes or openings in the wedge pins 137 'to secure the scaffolding in the position shown.

The frame 115 is equipped with damping pads 138, which in! Ig. 5 and 6, the upper side of the rails 135 come into contact and are fastened there with the aid of pins 139.

The ends 15I of the rails 148 are slidable and pivotable on a surface 152 of a support 153, so that they slide on the surface 152 and move up and down when the scaffold is tilted.

This arrangement for tilting the scaffolding from the vertical and the horizontal position Attach a crane hook to the lifting pin 154 and take up the weight of the scaffolding until the wedge, pins 137 can be removed. The key pins 142 are then loosened and the bolts 139 rotated by 90 °, whereupon the scaffolding in a simple manner by the crane can be promoted to its horizontal position.
