Definitions

  • the invention concerns an end-face sealing device between, on the one hand, rotating pairs of rolls and, on the other, stationary chambers. Sealing devices of this kind are particularly suitable for sealing a pair of pull-in rolls against the stationary walls of stufferbox crimping apparatus for crimping e.g. high-polymer filaments forming ropes.
  • German Auslegeschrift No. 1,435,441 discloses the idea of replacing the side-plates by pressure-applyin g belts which can be driven in the direction opposite to that in which the rope of filaments is moved.
  • German Offenlegungschrift No. 2,117,393 and also in German Auslegeschrift No. 1,959,863 there are described pressure discs which are mounted on an axis parallel to that of the pull-in rolls and which may be driven either on the basis of their being mounted offcentre or through a separate drive. All the known forms of side-plates or other sealing elements achieve the required seal by means of a pressure applied by the sealing elements to the rotating end-faces of the pull-in rolls.
  • the object of the present invention is therefore that of so locating a sealing device between, on the one hand, the rotating pairs of rolls and, on the other, the stationary chambers, particularly in a stufferbox crimping apparatus, for the purpose of sealing the pull-in rolls against the side-walls of the upsetting chamber that the position of the side-plates in relation to the end-faces of the pair of rolls is adjusted and fixed once and for all, and the side-plates no longer press on the rotating part of the pair of rolls, it being possible instead to maintain a gap between the side-plates and the end-faces of the pair of rolls. It is intended that it will be possible to reproduce the position of the side-plates with the least possible difficulty and expense should it be necessary to replace them.
  • this object is achieved in that the side-plates (hereinafter called sealing plates) are pressed on to the end-faces of sealing elements fitted in the end-faces of the rolls, and these sealing elements are mounted to be adjustable in the axial direction of the rolls and are prevented from rotating with the rolls.
  • the sealing elements are supported on the drive shafts of the rolls or the end-faces of the rolls by way of bearing elements and have adjusting means which permit adjustment of the position of the end-faces of the sealing elements in relation to the bearing elements and therefore of the position of these end-faces relative to the end-faces of the pair of rolls, before the apparatus is put into operation.
  • the position of the sealing plates, bearing on the end-faces of the sealing elements, in relation to the end-faces of the pair of rolls is fixed in a reproducible manner.
  • the drawing shows, partly in section, a stufferbox crimping apparatus, the sectional part being drawn on the plane that includes the axes of both pull-in rolls, the pull-in gap thus being seen as a line of contact between the two rolls.
  • the shafts 2 and 2 of the rolls 1 and 1' respectively are parallel to each other, and one of the two shafts is usually mounted for displacement towards or away from the other.
  • the roll mounted on this displaceable shaft is pressed by the usual pressure-applying means on to the second pull-in roll which is immovably mounted on the machine frame.
  • the two rolls move the textile material which is to be crimped and which is usually in the form of a rope of synthetic filaments, and passes it into the stufferbox chamber, not shown in the drawing, disposed downstream of the rolls.
  • the end-faces 3 and 3 of the pull-in rolls 1 and 1' respectively are machined and mounted with such precision that they lie in the same plane.
  • a bearing 4 and 4' mounted at each end-face of a pull-in roll 1 and l or on the associated roll-shafts is a bearing 4 and 4' respectively which is connected to an annular adjustable sealing element 5 and 5 respectively.
  • the sealing elements 5 and 5' do not have to rotate with the pull-in rolls, and instead they may be anchored by a suitable means, e.g. a pin.
  • the end-faces 6 and 6' of the annular sealing elements are precisely machined in just the same way as the end-faces 3 and 3 of the pull-in rolls, so that they too lie in the same plane.
  • the sealing plate 7 can be pressed against this plane formed by the end-faces 6 and 6.
  • the force used for pressing the sealing plate 7 and the means therefore employed are however unimportant as regards the functioning of the stufferbox crimping apparatus of the invention, since the position of the sealing plate in relation to the plane of the end-faces 3 and 3' is positively established by the annular adjustable sealing elements 5 and 5'.
  • the decisive factor as regards correct functioning is the distance between the plane formed by the end-faces 3 and 3 and the plane of the end-faces 6 and 6. This distance determines the sealing gap between the sealing plate 7 and the end-faces 3 and 3' of the pair of pull-in rolls.
  • the size of the sealing gap can be determined by the position of the sealing elements 5 and 5. It has been found advantageous to arrange for the position of the sealing elements 5 in relation to the bearings 4 and 4 to be adjustable and retainable by the use of known methods; in the simplest case set-screws, for example, are used for the purpose. It is thus possible to adjust the size of the sealing gap 8 between the plane of the endfaces 3 and 3 and the surface of the sealing plate 7 in the best possible manner, before putting the stufferbox crimping apparatus into operation for the first time.
  • these plates may be made of hard material, for example a sintered ceramic material, which is virtually undamaged by the crimped material.
  • sealing plates of soft materials such as brass or bronze can be used in the device of the invention and if required the plates may be disposed off-centre as described for example in German Auslegeschrift No. 1,959,863 or in German Offenlegungschrift No. 2,117,393.
  • An end-face sealing device between, on the one hand, rotating pairs of rolls and, on the other, stationary chambers which comprises a. sealing elements fitted in the end-faces of the rolls, being adjustable in the axial direction of the mils and prevented from turning with the rolls,
  • An end-face sealing device as claimed in ciaim 2 wherein the position of the end-faces of the sealing elements in relation to the bearing elements and therefore the position of these end-faces relative to the end-faces of the pair of rolls can be adjusted with the aid of known adjusting means prior to putting the device into operation, the position of the sealing plates, bearing against the end-faces of the sealing elements, being fixed in a reproducible manner relative to the end-faces of the pair of rolls.
