Definitions

  • the invention relates to a heating device according to the preamble of claim 1, as known from CH-A 377 037.
  • the guide surface for the material to be treated has thick-walled heating plates made of aluminum or magnesium which run at right angles to the movement path and into which cylindrical resistance heating elements are fitted. These heating elements directly heat up the heating plates, over the guide surface of which the material to be treated is drawn away.
  • DE-C 893 108 and 930 888 electrically heated rollers are described, in which heating rods are inserted in axially extending grooves that are open to the outside on the circumference of the roller core.
  • a heating device is created which has a uniform temperature over the entire width of the guideway, even if, for example, more heat is removed from the edge regions than the central region.
  • So-called heat pipes partly filled with a liquid and partly filled with their vapor are known per se and are characterized by the fact that the steam is always deposited on the coolest wall parts and releases its heat of condensation there. This ensures an extremely even heat distribution over the entire length of the heat pipes and thus over the entire width of the guide surface without any delay and without any control intervention from the outside using the simplest constructional means.
  • DE-B 22 11 658 shows an upright, elongated vessel, one wall of which is slightly curved as a guideway for the thread to be treated and electrical heating cartridges protrude into its lower part, which serves as a liquid collecting space.
  • DE-C 18 04 777 and 19 53 692 heating godets with a cross-sectionally annular heat pipe in the godet jacket.
  • US-A 36 19 539 a godet is shown, the entire slightly conical interior of which works as a heat pipe.
  • the invention Compared to heating devices with a single, correspondingly large-volume steam vessel, the invention, with its large number of small heat pipes, offers significantly increased security. Even if one of the pipes leaks, only a very small amount of liquid escapes and cannot endanger the environment.
  • the tubular shape of the heating elements and their small volume mean improved strength, especially since these small heat pipes are embedded in the surrounding metal support body. The failure of one of the heat pipes hardly affects the function of the entire heating device.
  • the manufacture of such small heat pipes is very simple. For example, they can be cut from oxygen-free copper tubes and, after filling with a predetermined small amount of water, squeezed off at their ends and soldered or welded tightly.
  • a plurality of threads 4 are pulled in the direction of arrows 3 over the heating plate 2 shown in FIG. 1, which is slightly curved on its surface 1.
  • the heat pipes 6 are embedded in the support body 5, for example made of aluminum or brass, e.g. poured or thrown. These are copper or aluminum pipes of suitable wall thickness, e.g. with an outer diameter of 9mm and a wall thickness of 2mm.
  • cylindrical heating rods 7 are also embedded in the support body 5 parallel to the heat pipes but offset relative to these, preferably cast or pressed in with the heat pipes 6 in one operation.
  • the heat pipes 6 are tightly closed. They contain a small amount of a liquid, preferably water, which evaporates at the desired treatment temperature. They can be used up to temperatures of 360 ° C. When using aluminum tubes you can go up to 15o ° C. A steel support ring for the heat pipes would allow temperatures up to 250 ° C.
  • the heating plate 2 is divided into several segments 2a to 2c, which can be heated to different temperatures if necessary. 2 shows a particularly advantageous structure of such segments.
  • the heating plate here consists of an aluminum base body 8 tempered on its surface 1, which is provided on its side facing away from the thread running surface with semi-cylindrical grooves 9.
  • the heat pipes 6 are inserted into these grooves and are held therein by a two-part supporting body 5a, 5b which has corresponding semi-cylindrical grooves 10 on its side facing the base body 8.
  • a two-part supporting body 5a, 5b which has corresponding semi-cylindrical grooves 10 on its side facing the base body 8.
  • each part 5a and 5b of the support body also has semi-cylindrical grooves 11, which together accommodate the heating rods 7.
  • Both support body parts 5a and 5b are of the same shape and are produced, for example, as an aluminum drawing profile.
  • the webs 12 provided on the base body 8 and widened at the end in a T-shape serve to fix the position of the support body 5a, 5b and the heat pipes 6 and the heating rods 7.
  • flat springs 13 made of prestressed steel sheet are inserted between the T-shaped widenings 14 and the base body 8 supporting body part 5b facing away indented. If necessary, several such segments 2a to 2c of the base body can be lined up and braced in a suitable manner to form a large-area heating plate.
  • the support body 5a, 5b can also be made of another good heat-conducting material, for example copper or brass.
  • a resistance heating device is provided as the heating device for the heat pipes, in which heating rods embedded in the roller, roller or godet jacket and extending parallel to the godet shaft are supplied with current via slip rings.
  • the resistance heating device can also be arranged in a stationary manner and the heat can be transmitted to the godet jacket and the heat pipes embedded therein by radiation or a transmission medium.
