Abstract: A device for gripping and guiding a bar of material into the nip of the rolls of a rolling mill. At least two opposed guide rollers are moveably mounted on an appropriate support, such as a gripping arm of a manipulator head for a rolling mill. The guide rollers are moveable towards one another into a gripping position for gripping the edges of a bar of material being introduced into the rolling mill nip. The guide rollers are moveable away from one another and out of engagement with the bar of material. A bar is readily gripped by the opposed rollers and is quite free to be advanced into the roller nip since the guide rollers are free to rotate. One or more rollers may include a ratchet to prevent rotation in the opposite direction such that any tendency of a bar of material to be thrown back out of the roll nip will be resisted.

Abstract: The present invention is directed to an extraction device for use in continuous rolling mills for extracting tubes from retaining mandrels. The extraction device includes a frame having three pressure yielding rollers mounted therein. The rollers are normally retained in a fixed position for performing a final reduction on the tubes. However, if a mandrel on which the tube has been rolled accidentally enters the orifice defined by the three rollers, the rollers will yield to the excessive pressure and move away from the center of the frame by an amount corresponding to the maximum diameter of the tube containing the mandrel.
