The strip casting machine according to claim 5, characterized in that the in the second step supporting element (9, 29, 43) displaces the side part (4, 24, 42) about a pivoting axis (11) or along a curve. 8. The strip casting machine according to claim 5, characterized in that the in the second step supporting element (9, 29, 43) displaces the side part (4, 24, 42), essentially horizontal. 9. The strip casting machine according to claim 8, characterized in that a horizontal displacement (14, 14``) of the side part (4, 24, 42) is provided along a horizontal displacement guide (46) which is at a height (49) beneath the supporting space of the casting rolls (2, 3, 22, 39). 10. The strip casting machine according to claim 9, characterized in that a horizontal displacement guide (46) displaces the side part (42) to a position of side parts exchanging. 11. The strip casting machine according to claims 1 to 10, characterized in that the side part (4, 24, 42) is adapted to displace downwards between bearing roll necks (2, 3, 22, 39) forming a space therebetween, if necessary. 12. The strip casting machine according to claims 1 to 11, characterized in that a setting device (27) is provided with a cylinder-piston units (30) for moving a side part (24) between a setting position and a casting position. 13. The strip casting machine according to claim 12, characterized in that the setting device (27) is arranged on the machine stand (21) adapted to be connected to the side part (24) in a setting position and disconnected from it. 14. The strip casting machine according to claims 1 to 13, characterized in that the side part (24, 42) remains connected to the support arm (29, 43) in the casting position. 15. The strip casting machine according to claims 12 to 14, characterized in that the side part (24) is adapted to displace downwards together with the setting device (27) (fig.3). 16. The strip casting machine according to claim 12, characterized in that the setting device (27) is centered in a setting position of the side part (24) on the machine stand (21), wherein in the step of leading the side part (24), the machine stand maintains the setting effort. 17. The strip casting machine according to claims 1 to 16, characterized in that the side part (24) is adapted to displace downwards between the front sides of roll bodies and the machine stand (21) (fig. 2, 3). 18. The strip casting machine according to claims 1 to 17, characterized in that the support rod (43) consists of a vertical and horizontal members (44), the horizontal member is connected to a lifting means (45). 19. The strip casting machine according to claims 1 to 18, characterized in that the horizontal displacement guide (46) is provided with a cable drive chain (48) for the side parts feeding ducts. 20. The strip casting machine according to claims 1 to 19, characterized in that the side parts (60) are provided with electromagnetic coils (61, 61`) for generating an electromagnetic field for side sealing (fig. 6). 21. The strip casting machine according to claims 1 to 20, characterized in that the different width of roll bodies (22) can be compensated at the expense of intermediate elements (32) inserted between the side part (24) and the setting device (27) (fig. 3). 22. The strip casting machine according to claims 1 to 21, characterized in that two devices (40, 41) are arranged on both sides of the casting rolls (2, 3, 22, 39) for changing side parts, a worn side part (4, 24, 42) is removed by one device (14) and replace by another device (14`). 23. The strip casting machine according to claims 1 to 22, characterized in that the side parts (42, 42`) are adapted for protruding using said support arm from the setting position via a locking aperture (51) from a chamber (50) filled by inert gas and placing into a lock chamber (52, 52`). 24. The strip casting machine according to claim 23, characterized in that the side part (42) is protruded from the lock chamber (52, 52`) thanks to relative movement between the device (40, 41) for replacing side parts and the lock chamber (52, 52`), and directed into a repair shop using a transportation means (55). 25.
