Similarly, rotation of the set screw 50 results counterclockwise rotation of the adjusting plate 30 in the opposite direction, since the spring element 48 is expanded is, whereby the end of the set screw 50 is held in contact with support 52,

As best seen in Figure 5, the head unit is ^ 28 also includes a tubular extension 72 having a cylindrical passage 74 extending axially therethrough runs. A stripper bit 76 adapted to be inserted between the work rolls 78 is provided with a fixedly welded tubular extension 78 of reduced diameter which axially inserted into the cylindrical passage 74 when the stripper bit is attached to the head assembly 28 will. The tubular extension 78 is also provided with a peripheral hat 80 in which a compressible Ring 82 is located. In this construction, the scraper bit is removed by simply inserting the ring 82 built into the peripheral groove 80 and by subsequently inserting the tubular extension axially into the passage 74 to the point where the welded-on shoulders 83 meet the front surface of the cylindrical Touch extension 82 at 85. It can therefore be seen that with this construction a loiohte pivoting movement of the stripping chisel 8 relative to the head unit 22 by points is possible, and zv / ar due to the fact that the outer diameter of the tubular extension 78 is smaller than the inner diameter of the passage 74

In FIG. 4, the rolling stock 90, which has an essentially normal cross-section, is shown immediately before contact by the twist rollers 58. This illustration shows that when the salt material enters the guide track 62 between the twist rollers 58, it is grasped on each side at 94. This gripping communicates a twist to the rolling stock, as a result of which it rotates in the conventional manner as it moves further in the direction of the next following roll stand. The rolling stock is guided after its exit from the twist path 62 by means of a feed pipe 96, which is inserted axially through the tubular hollow element 26 and is held in place by means of a set screw 98 »Pipe 96 is suitably tapered compared to the twist rollers 58 at 100 , whereby a tight attachment to the twist rollers is possible.

With this construction, the guide rollers can be permanently cooled and lubricated independently of the rotational position of the hollow element 26 within the outer housing structure 18.

According to the description of the elixir preferred form of training The invention, which is illustrated in the accompanying drawings, is now intended to provide some of the advantages gained thereby are briefly listed compared to conventional rolling operations. By rotatable attachment of the scraper. , chisel 76 directly to head unit 28, which rotates the contains attached swirl rollers, a significant advantage is gained in that there is no intervening More support structure is required. This increases the distance between the preceding work rolls and the Twist rollers significantly reduced and thus a greater distance between the twist rollers and the next one Roll stand created. Since - as already mentioned - the extent of the twist that must be communicated to the rolling stock, is inversely proportional to the distance between the twist rollers and the next following roll stand, the amount of twist is reduced accordingly by increasing this distance.

Advantages are also gained from the special Vorriohtung for attaching the scraper to the Head unit.
