Abstract: 1. Thread brake, comprising two pliablely pressed to each other loading elements (46), disk-shaped or plate braking elements (10), between which at least one braking thread (11) is passed therethrough and of which at least one braking element has a central aperture (44), dowel-like supporting elements (20) which pass through said central aperture (44), of at least one braking element and on which rotatably arranged this braking element, sustaining members for the supporting elements, wherein sustaining members comprise substantially U-shaped clamp (19), which has two spaced on both sides of the braking elements (10) elbows (21) and on which supporting elements (20) are fastened with at least one supporting detail (33, 47), arranged on at least one of elbows (21) of the clamp or connected to it. 2. The brake of Claim 1, characterized in that the clamp (19) is a detail, made of one-piece, bent wire. 3. The brake of Claim 1, characterized in that the clamp is provided with supporting details (47, 47a) as ears. 4. The brake of any presiding Claim, characterized in that the clamp (19) has two parallel each other portions (25) with which it is arranged in a fitting detail (14). 5. The brake of Claim 4, characterized in that the portions of the lamp are arranged in the fitting detail (14) enabling lateral movement. 6. The brake of Claim 5, characterized in that at least one of portions (25) of the clamp is designed for connection with oscillator (29) to transmit the clamp reciprocating fluctuation movement. 7. The brake of Claim 6, characterized in that at least one portion (25) of the clamp is loaded with return spring members (30), elastically pressing on it to the predetermined final position. 8. The brake of one of Claims 2-7, characterized in that both elbows (21) of the clamp have a bent (23). 9. The brake of one of Claims 4-8, characterized in that the supporting detail (33) is made enabling to be removed from the clamp (19). 10. The brake of one of Claims 4-9, characterized in that the supporting detail (33b) is arranged on the clamp (19) enabling to move. 11. The brake of one of Claims 4-10, characterized in that the supporting detail is essentially U-shaped frame (33). 12. The brake of Claim 11, characterized in that the frame (33, 33a) is arranged on the clamp enabling to be fixed. 13. The brake of Claim 11 or 12, characterized in that the frame (33) is arranged on the clamp (19) enabling to turn between operative and non-operative positions and is made to fix the clamp in the operative position. 14. The brake of one of Claims 11-13, characterized in that the frame (33) has a portion (40), working as a supporting member for the braking elements. 15. The brake of one of Claims 11-14, characterized in that the frame (33a) is arranged on the clamp (19) enabling to move apart. 16. The brake of one of Claims 11-15, characterized in that the frame (33c) is detachable. 17. The brake of Claim 14, characterized in that the supporting elements (20) are arranged with one their end being on one side of the frame on one elbow, enabling to turn, whilst the other side of the frame comprises setting seats (50) for the other end of the supporting elements. 18. The brake of one of Claims 4-17, characterized in that the supporting detail (33) ps made of plastic. 19. The brake of any presiding Claim, characterized in that the supporting elements (20) are mounted on the supporting detail (33, 47, 47a) detachably. 20. The brake of any presiding Claim, characterized in that the supporting elements (20) are held by the supporting detail (33, 47, 47a) in electrical conducting connection with the clamp (19), the latter is designed for grounding. 21. The brake of any presiding Claim, characterized in that in its operative position the supporting detail (33, 47, 47a) is arranged at an angle to the vertical. 22. The brake of any presiding Claim, characterized in that comprises at least one thread guiding device (16) interacting with the clamp (19). 23. The brake of any presiding Claims, characterized in that the supporting elements (20)are held on the clamp (19) by their both ends. 24. The brake of any presiding Claims, characterized in that the supporting elements comprise disk-shaped or plate-braking elements (10), with which magnetic loading units (46) come into contact, said units are enclosed into housing. 25. The brake of any presiding Claims, characterized in that the braking system comprise disk-shaped or plate braking elements (10), arranged on the supporting elements (20) via a annular hub. 26. The thread feeder, comprising a housing (1), a thread feeding drum (6) mounted on it and enabling to rotate, a driving means (8), connected to the thread feeding drum, thread guiding devices (12, 18), arranged on the housing, and due to which a thread (11) is fed to the thread feeding drum and diverted to a thread user, and a brake (9) mounted also on the housing and arranged on the side of the thread feeding according to one of the presiding Claims. 27. A device of Claim 26, characterized in that the thread brake (9) comprises the clamp (19) having parallel portions (25), arranged either in the housing (1) or connected to it via the fitting detail (14).
