1. A device for moving a roll stand into or out of a roll stand receptacle of a rolling line, comprising: a first carrier element configured to entrain an entrainment element of said roll stand when said roll stand is in the roll stand receptacle of the rolling line and when said roll stand is on a roll stand changing cart; anda conveying element including a first end adjacent to the roll stand receptacle and a second end adjacent to the roll stand changing cart, wherein said conveying element is configured to move said first carrier element along a predetermined curved path to cause (i) said roll stand to move from said roll stand receptacle to said roll stand changing cart, and (ii) said roll stand to move from said roll stand changing cart to said roll stand receptacle. 2. The device of claim 1, wherein said predetermined curved path lies in one of: a plane perpendicular to said rolling line, a plane parallel to said rolling line, and a plane containing said rolling line. 3. The device of claim 1 further comprising: a second carrier element, said first and second carrier elements spaced apart from one another in a direction transverse to a direction of movement of said first and second carrier elements. 4. The device of claim 1, comprising: a second carrier element, wherein each of said first and second carrier elements are configured to travel along the predetermined curved path. 5. The device of claim 1, wherein said conveying element is configured to revolve. 6. The device of claim 1, said conveying element comprising: two revolving conveying elements, wherein a first revolving conveying element of said two revolving conveying elements is disposed parallel to a second revolving conveying element of said two revolving conveying elements. 7. The device of claim 1, wherein said conveying element is configured as one of: a cord, a chain and a belt. 8. The device of claim 1, wherein said carrier element comprises multiple parts. 9. The device of claim 1, wherein said carrier element is configured to define an essentially U-shaped recess. 10. The device of claim 1, wherein said carrier element is pivotably connected to said conveying element. 11. The device of claim 1, said conveying element comprising: a traction mechanism connected to a first part of said carrier element; andpivotally connecting a second part of said carrier element to the traction mechanism, wherein said second part of the carrier element is supported by a spherical contact surface of the first part of the carrier element. 12. The device of claim 1, further comprising: a drive connected to said conveying element, wherein said drive is configured to rotate said conveying element along a path, said carrier element on the conveying element adapted to follow said path, said path including a reciprocating translating motion transverse to the rolling line, a motion along a first curve to provide a raising movement of the carrier element, and a motion along a second curve to provide a lowering movement of the carrier element. 13. The device of claim 1, wherein said carrier element is configured as one of: a mandrel, a pin, and a hook. 14. The device of claim 1, further comprising a sliding surface, configured to permit a wheel-less roll stand to slide, while moved by the carrier element and entrained by said entrainment element, the sliding surface supporting the roll stand. 15. The device of claim 1, wherein said roll stand comprises rolls configured for rolling one of rod-shaped and tubular members. 16. A method of moving a roll stand into or out of a roll stand receptacle of a rolling line, comprising: positioning a first end of a conveying element adjacent to the roll stand receptacle and a second end of the conveying element adjacent to a roll stand changing cart;arranging a first carrier element on the conveying element, such that the first carrier element is in contact with a first entrainment element of the roll stand while said roll stand is in said roll stand receptacle of the rolling line; andmoving the first carrier element such that the carrier element follows a predetermined curved path along said conveying element and causes (i) said roll stand to move from said roll stand receptacle to said roll stand changing cart, and (ii) said roll stand to move from said roll stand changing cart to said roll stand receptacle. 17. The method of claim 16, wherein the carrier element is configured to receive the entrainment element of the roll stand. 18. The method of claim 17, further comprising: defining in said carrier element, a recess configured to be substantially U-shaped. 19. The method of claim 16, further comprising: coupling the entrainment element to the roll stand via an extension arm. 20. The method of claim 16, further comprising: engaging said first carrier element and a second carrier element with said first entrainment element and a second entrainment element of the roll stand, respectively, on an operating side of the roll stand, wherein said first and second carrier elements are spaced apart from each other in a direction of the rolling line. 21. The method of claim 20, further comprising: providing translational movement of said first and second carrier elements in a direction transverse to the direction of the rolling line, wherein said first and second carrier elements are adapted to impart movement of the roll stand via the corresponding first and second of entrainment elements of the roll stand. 22. The method of claim 21, further comprising: moving said roll stand in a direction transverse to the rolling line, thereby separating the roll stand from a roll stand receptacle in the rolling line; andengaging a third carrier element and a fourth carrier element associated with the conveying element with a third entrainment element and a fourth entrainment element of the roll stand, respectively, said third and fourth entrainment elements of the roll stand located on a drive side of the roll stand opposite the operating side.
