  • the end portion E2 has at least partially an outer dimension, or a diameter d3, which is greater than the diameter d2 of the through hole 12 through which the center portion 14 of the threaded bolt protrudes.
  • a compression spring in the form of a helical spring 30 is mounted on the central portion 14 of the threaded bolt 6.
  • a wave spring 31 may be used, which in the example of Figure 4 will be shown.
  • the outer diameter of the respective spring element 30, or 31 is selected so that the spring element projects beyond the through hole 12 and comes to rest on the inner support surface 26 of the base body.
  • the respective holding element 40 has a first section 41 (for example, cylindrical), which projects into the depressions V1 and V2 of the main body 5. This is followed by another section 42 (cylindrical or square), which projects into a longitudinal slot 45 which extends in the longitudinal direction L of the retaining rod H1.
  • the adjoining the section 42 end portion 43 of the holding member 40 may for example have a square or rectangular cross-sectional shape, as z. B. in the representation of Fig.2 indicated on the right side.

  • the spring element 30 When screwing the first end portion E1 in the holding member 10, the spring element 30 is compressed and tensioned. Since the spring element 30 (31) is supported on the inner support surface 26, a force M is generated by the, resulting in tensioning of the spring element spring force, over which the second end portion E2 of the threaded bolt 6 is pushed away from the inner support surface of the main body 5 , This is also the case, via the retaining element 10 with the threaded bolt connected combing element with its base F1 pressed against the peripheral surface U of the base body 5 in the region of the support ribs S1, S2, or braced. A coating of the respective threaded bolt is thus excluded, since this comes with its paragraph 15 to an end stop on the surface 17 of the holding element.
  • the combing element is clamped exclusively on the resulting spring force of the spring element 30 (31) against the outer circumference U of the body and fixed in this position.
  • the tightening torque of the threaded bolt has no influence on the contact pressure, with which the respective combing element is clamped against the peripheral surface U of the main body 5, or pressed.
  • the retaining element 40 shown there is not screwed into the support rod H1, but laterally inserted over its end portion 43 in a longitudinal slot 47 of the retaining rod, as partially on the right side of the representation of Fig.2 is pictured.
  • the inserted holding elements are positioned so that their threaded hole 18 of the respective passage opening 12 of the main body facing. It is also conceivable to provide markings in the region of the base area F1 of the retaining rod H1, by means of which the retaining elements 40 can already be brought into the correct position during insertion into the longitudinal slot 47.
  • the respective holding element 40 could also be connected via a weld with the support rod H1. It is also conceivable to connect the holding element to the holding bar via an adhesive connection. Another possibility would be a one-piece molding of a holding element to the support rod. In these cases, the respective holding element is fixed and permanently connected to the holding element.
  • the proposed fastening of the combing elements on a base support of a circular comb allows for easy and quick assembly and disassembly of the combing elements, wherein the tightening torque of the threaded bolt used exerts no influence on the contact pressure of the respective combing element on the outer circumference U of the body.
