Definitions

  • the present Erfindun q relates to a device for treating elongate structures.
  • Devices of this type are used for treating yarns, for example.
  • Known devices of this type have a mandrel provided with a heating element and having a cylindrical surface. This mandrel forms part of an apparatus for acting on the yarn.
  • the yarn is passed around the heated mandrel in several turns.
  • the material of the yarn heats up and, depending on the other conditions prevailing in the device, the yarn can be stretched or shrunk.
  • the temperature of the mandrel must be set precisely according to the properties of the yarn. In addition, this temperature must be maintained as precisely as possible during the operation of the facility. That is why each mandrel is equipped with an appropriate temperature sensor and a powerful temperature controller.
  • the object of the present invention is to eliminate the mentioned disadvantages of the known device of the type mentioned.
  • the device for treating elongated structures has a housing 1 which is elongated in the direction perpendicular to the plane of the drawing.
  • a housing 1 which is elongated in the direction perpendicular to the plane of the drawing.
  • a plurality of hollow bodies 2 are attached side by side, of which are shown in the only a single body 2 can be seen.
  • the hollow bodies 2 contain a conical jacket 3, the wider end part of such a body 2 being connected to the housing 1.
  • the narrower end part of the conical body 3 is closed off with the aid of a base 4.
  • the housing 1 and the conical bodies 2 form a cavity which is airtight.
  • radiators 5 which are intended for heating a heat transfer medium 13.
  • Oil with an evaporation temperature is usually used as the heat carrier 13, the height of which is selected in accordance with the treatment purpose of the yarns.
  • the heat transfer medium 13 which is located in the lower part of the housing 1, is only heated until the heat transfer medium is located inside the device both as a liquid and as a vapor. This makes it easiest to keep the temperature of the device constant.
  • the housing 1 and partly also the cone-shaped body 2 are surrounded by an insulating jacket 6, which should reduce heat losses as far as possible and which is not part of the invention.
  • the respective conical body 2 serves as a support for an apparatus for the actual action on the respective yarn 14 (FIG. 4).
  • One half of an externally cylindrical mandrel 7 is shown in FIG. 1 above the conical body 2. This mandrel 7 forms part of the above-mentioned apparatus for acting on the yarn 14.
  • the entire cylindrical mandrel 7 is shown in FIG. 3, with a mandrel 8 being associated with this mandrel 7 here. 4 two of the apparatuses arranged next to one another for acting on the yarn 14 are shown.
  • the yarn 14 is fed to the mandrel 7 via the guide roller 8.
  • the Leitrol le 8 is mounted in a holder 9 which is attached to the insulating jacket 6.
  • the mandrel 7 is hollow and its inner wall is conical, so that the mandrel 7 can be attached to the jacket 3 of the support body 2.
  • the friction between the material of the mandrel 7 and that of the jacket 3 prevents the mandrel from rotating on the support body 2. This is important because in this way one can achieve the coefficient of friction required for the treatment of the yarn 14 between the mandrel 7 and the yarn 14.
  • a nut 10 is attached to the outside of the bottom 4 of the support body 2, into which a screw 11 can be screwed. This screw 11 passes through a plate 12 with a central opening, the edge part of which presses the mandrel 7 against the supporting body 2.
  • Fig. 1 half of another embodiment of the apparatus for acting on the yarn is shown below the support body 2. 5 and 6.
  • the embodiment of the apparatus shown in the cited figures contains a flat base body 15, which is made from a piece of a good heat-conducting material, for example aluminum .
  • the main surfaces 16 and 17 of the base body 15 are curved, so that the edge portions of the base body 15 are narrower than the central portion thereof.
  • a conical opening 18 is made, which makes it possible to open the base body 15 onto the jacket 3 of the support body 2 stuck.
  • the base body 15 is pressed against the jacket 3 of the support body 2 with the aid of the pressure plate 12 already mentioned and the screw 11 also mentioned. Pressing the base body 15 against the support body 2 ensures good heat transfer from the support body 2 to the base body 15.
  • the narrower edge parts of the flat base body 15 have recesses 19 and 20 with a curved bottom part. These recesses 19 and 20 extend essentially parallel to the axis of symmetry of the cone-shaped opening 18 in the base body 15. In each of these recesses 19 and 20 there is a deflection roller 21 and 22, respectively, between the surface of the deflection rollers 21 and 22 and the bottom part of the corresponding recess 19 or 20 there is a gap 23 or 24 of constant width.
  • the yarn slides during the heat treatment thereof on the two main surfaces 16 and 17 of the heated, flat base body 15, the direction of movement of the yarn at the ends of the flat base body 15 being changed by means of the deflection rollers 21 and 22.
  • the number of turns in which the yarn 14 is wrapped around the apparatus corresponds to the type of yarn treatment desired.
  • the respective deflection roller 21 and 22 is qelaqert in a tab 25 and 26 which is slidably attached to the base body 15.
  • the respective tab 25 or 26 is in good thermal contact with the base body 15.
  • the gaps 23 and 24 can be very small because the deflection rollers 21 and 22 are attached to the base body 15 itself. Since the deflection rollers 21 and 22 are led to q e via the tabs 25 and 26 by the base body 15, the yarn suffers practically no cold shock during the deflection on the rollers 21 and 22. This has a very advantageous effect when treating yarns.
  • the fastening of the deflection rollers 21 and 22 can be seen in detail from the lower half of FIG. 1.
  • the rear side of the base body 15 is provided with a hole 27 in which a thread is made.
  • the tab 26 is provided with an elongated hole 28 through which a screw 29 screwed into the threaded hole 27 passes.
  • the desired size of the gap 23 or 24 between the deflection roller 21 or 22 and the bottom part of the recess 19 or 20 is first set and then this gap is ensured by tightening the screw 29 just mentioned.
  • the apparatus set in this way can then be plugged onto the supporting body 2.
  • This device also has a housing 40 which is elongated and is provided with a plurality of support bodies 41. However, the axis of the respective support body 41 runs vertically. During the operation of such a device, the liquid heat transfer medium at least partially fills the support body 41. Therefore, the heating of the heat transfer medium has to be taken care of in a different way.
  • There is a sleeve 42 is provided passing through the housing eht q 40 and extends to the bottom 43 of the supporting body 41, where it is sealed to the bottom 43rd The other end of the sleeve 42 is connected to an opening 44 in the upper wall 45 of the housing 40 tightly connected.
  • a heater 46 is inserted into the sleeve 42.
  • the outer side of the bottom 43 of the support body 41 is provided with the nut 10 already discussed, so that one of the above-described embodiments of the apparatus mentioned can be attached to the respective vertically arranged support body 41 in the manner described.
  • a single temperature sensor 47 which is advantageously attached to the housing 1 or 40, is therefore sufficient to regulate the working temperature in this device.
  • This temperature sensor 47 is connected by means of lines 48 to a known temperature controller (not shown) which feeds the radiators 5 and 46, respectively. It is therefore sufficient to use a single temperature sensor 47 and a simple temperature controller. This makes the present device not only inexpensive but also less prone to malfunction.
  • the deflection rollers 21 and 22 can be provided with circumferential grooves.
  • this device for treating elongated structures has the housing 1, which is elongated in the direction perpendicular to the plane of the drawing is.
  • This housing 1 is provided with apparatuses 50 for treating elongated structures, of which only a single apparatus 50 can be seen in the section shown.
  • the radiators 5 which are intended for heating the heat transfer medium 13.
  • Oil with an evaporation temperature the level of which is selected according to the treatment purpose of the structures, is usually used as the heat carrier 13.
  • the heat transfer medium 13 which is located in the lower part of the housing 1, is only heated until the heat transfer medium is located inside the device both as a liquid and as a vapor. This makes it easiest to keep the temperature of the device constant.
  • the housing 1 is surrounded by the insulating jacket 6, which should reduce heat losses as far as possible and which is not part of the invention.
  • a tube 51 is provided which passes through the housing 1.
  • One end part 52 of this tube 51 is fastened in an airtight manner in an opening in the rear wall 53 of the housing 1, the remaining part of this rear end part 52 being so long that it looks out of the insulating jacket 6.
  • the front wall 54 of the housing 1 has an opening 55, the diameter of which is larger than the outer diameter of the tube 51. There is thus an opening between the outside of the tube 51 and the edge of the opening 55. The front end portion 56 of the tube 51 then protrudes from the housing 1.
  • a sleeve 57 adjoins the edge of the opening 55 in the front wall 54 of the housing 1 and runs coaxially with the tube 51.
  • the front end of the tube 51 and that the front end of the sleeve 57 are connected to one another by means of an annular front wall 58.
  • the front end part 56 of the tube 51, the sleeve 57 and the front wall 58 together form a hollow extension 60 which adjoins the interior of the housing 1.
  • this has a circular cross section, so that the outer surface of this extension 60, the is defined by the sleeve 57, is cylindrical.
  • the tube 51 forms the inner wall of this extension 60.
  • extension 60 there is virtually the same temperature as 1. Since the projections rate 60 all mounted on the housing 1. A p pa- 50 conformed to the interior of the housing, prevail in these same conditions, and thus the same temperature.
  • the apparatus 50 also has a roller 61, which is intended for the treatment of the elongate structure.
  • Such rolls 61 have hitherto been used as so-called draw rolls on draw twisting machines.
  • the roller 61 is hollow and has an approximately U-shaped cross section. In the center of the roller 61 there is a hub 62 via this hub 62 is the part connected to a shaft 63 61 s in the pipe 51 by means of Kugella q is stored for 64 and 65 thereof.
  • the inside of the ring 66 of the roller 61 lies as close as possible to the surface of the sleeve 57, so that the roller 61 is in intimate thermal contact with the extension 60.
  • the required amount of heat reaches the elongated structure to be treated, which wraps around the roller 61 and the laying roller 22, via the extension 60 and the roller ring 66.
  • the ball bearings 64 and 65 are in a lining 67 einqe sets, which is located in tube 51.
  • the distance between the ball bearings 64 and 65 is defined with the aid of spacers 68 and 69.
  • the bearing of the shaft 63 is sealed by means of locking pieces 70 and 71. This ball bearing unit is inserted into the tube 51 when the device is assembled.
