  • Cross-sectional shape size and cross-section of the recess conforms in terms of form and which stipulates in order to maintain close tolerances but with play on the recess wall.
  • the one from the Drawing recognizable distance between the wall of the holes and the outer surface of the thread guide is only for the sake of Clarity exaggerated.
  • a part of each thread guide 32 projects into the longitudinal grooves 12, in such a way that on opposite sides of the grooves 12 successively arranged thread guides 32 to a certain extent, e.g. 0.1 to 1 mm, over a parallel to the walls 18, 20, 22 Middle plane. Otherwise, the width of the slots 30 each less than the largest cross-sectional dimension, d. h .: than that Diameter of the thread guide 32 so that it does not come out of the recesses 28 can slide out.
  • both the recesses are 28 as well as the thread guides 32 of circular cylindrical cross section.
  • Other angular and rounded shapes such as ellipses, rhombuses, Triangles, etc. are conceivable.
  • the embodiment according to FIGS. 1, 2 has one that is kept within tight tolerances Fit between recesses 28 and thread guides 32. Therefore there is no need for separate fasteners to secure the thread guides 32 against axial and radial displacements, which makes it a special one Effort that would result from the use of fasteners, is avoided. 4 and 5 match fits are selected. On the one hand, these game fits are narrow enough so that the thread guides are immobile in their recesses lie.
  • Sheet metal caps 52 serve in the axial direction.
  • the side walls have 18, 20, 22 at their upper edge retaining grooves 54 or a head 56, which is wider than the respective wall.
  • the sheet metal caps 52 have in cross section a cup-shaped profile, so that in the case of Project the central wall 20 into the retaining grooves 54 or in the case of the Side walls 18, 22 encompass the wall head 56.
  • the sheet metal caps formed as elongated profiles, the length of which Length of the heating rail corresponds.
  • the thickness of the wall heads 56 or the position of the holding grooves 54 and the corresponding dimensioning the sheet metal caps is such that the sheet metal caps are the thread guides in Set the axial direction.
  • the thread guides consist of the usual materials such as Silicon, titanium, or aluminum oxides or from nitrided or hard chromed steel, or the like
  • the thread guides 32 are preferably in the area in which they come from protrude the recess slot 30 on their from the lower part 16 opposite ends beveled as shown at 34. Thereby form those in opposite walls 18 and 20, or 22 and 20 one behind the other thread guide 32 in the cross-sectional direction of the Heater 10 each have a V-shaped groove 36 which enables a thread 38 in the stretched state without any special measures or arrangements between the successive thread guides 32 in one with respect to the heating surface 12 and the lower part 16 substantially vertical movement between the thread guides 32 too to lead. There forms the thread 32 resting on the contact surfaces then a zigzag thread path (see Fig. 1).
  • the heating device 10 can consist of two in Thread running direction one behind the other rail sections 14a and 14b exist. These are of different lengths, but otherwise same cross-sectional shape. Purpose of such a two-part arrangement it may be the heater 10 in different length ranges heat differently to the thread 38 at one to treat its properties in accordance with its thermal profile. That means: You can also do more than the two sections shown be applied. It is of particular importance that the Angle that the two heating rails form to each other, at each Processing point of the false twist crimping machine set identically threads of the same quality on all processing points be generated. One is used to attach the two heating rails Mounting rail 58. This is a rail that the Has length of the two heating rails.
  • the mounting rail has one U-shaped cross section.
  • the heating rails are on the bottom of the Fastening rail fastened with spacers 60. By dimensioning the spacer and its position relative to the heating rail, is the inclination of the heating rail in relation to the straight Fixing rail 58 set.
  • the two have Heating rails of opposite inclination and together form one obtuse angle.
  • the mounting rail 58 thus serves on the one hand exact fastening of the two heating rails. Because the mounting rail 58 has a U-shaped profile, but also encompasses the two heating rails. Therefore, the mounting rail 58 also serves Temperature equalization over the length and width of the heating rails.
  • the mounting rail is surrounded with insulation.
  • rod-shaped spacers 40 can be provided, the longitudinal groove 12 on the groove bottom, d. H. bridge the heating surface and the thread run in an exact Specify the distance to the base of the groove.
  • the circumferential grooves have the same depth over the circumference, so they are concentric to the thread guides 32 are formed.
  • the heating device 10 is in an insulating box 44 (Fig. 2) housed in a thermal insulation material, e.g. Glass fibers, is embedded.
  • the insulating box 44 can with a Flap (not shown) may be provided, which makes it possible to open to provide access to the heater 10 and the Insert thread.
