Definitions

  • the invention relates to a press or web guide roller with a rotatable roller tube, the outer surface of which is provided with grooves with a predominant directional component in the circumferential direction.
  • Web guide rollers are used to feed a web, e.g. made of paper, cardboard, plastic, metal, textile or the like. from one point in a machine system to the next point at which further processing of the web is carried out, for example by pressing, embossing, printing, rolling, smoothing, dewatering, coating, winding up or the like, if necessary with a controllable or adjustable tension.
  • a web e.g. made of paper, cardboard, plastic, metal, textile or the like.
  • the exact transfer of the web by means of the web guide roller is problematic, since an air cushion forms on the outer surface of the web guide roller and the web on which the web begins to float, so that it performs uncontrolled movements in the lateral direction and no lateral guidance the web is more guaranteed.
  • Press rolls serve to dewater fibrous webs and are mainly provided with circumferential grooves.
  • the roller tube from a lighter material, for example from fiber-reinforced plastic, which, however, has only a low surface hardness. Therefore, there are rapid signs of wear and tear due to abrasion of the grooves, so that the possible operating time of such web guide rolls is often insufficient.
  • the invention has for its object to avoid the above-mentioned disadvantages of the prior art and to provide a press or web guide roller which has a lower mass, greater wear resistance and less wear on the roller surface even at higher web speeds, which in the Design as a web guide roller allows automatic guiding of the web even at higher web speeds and speeds while avoiding lateral deflection of the web, without the need for complex and complicated measuring and control devices.
  • this object is achieved in that the grooves are formed by at least one layer of a material with better strength than that of the roller tube, wrapped around the outer surface of the roller tube.
  • roller tube made of plastic results in a better vibration behavior due to the better damping, especially in the case of press rollers.
  • the wound layer advantageously consists of a wire or band made of metal, a fiber-reinforced plastic or another suitable material with good abrasion resistance.
  • the cross section of the wound wire can be selected to be circular, elliptical, rectangular, square, triangular or similar. However, it is particularly advantageous to grind the outer surface of the outer layer so that a cylindrical surface with grooves is formed between the windings. For certain webs, however, an outer shape with wavy grooves is also advantageous, as can be achieved, for example, by winding up a corrugated band.
  • the winding of the layer is carried out with the surface of the plastic roller tube still just flowing, so that the winding is partially embedded in the plastic surface.
  • a prior conditioning of the material to be wound up is expedient, with which reliable adhesion to the plastic of the roller tube is achieved.
  • plastic tube is too flexible, it is advisable to support the tube from the inside with the help of air or liquid bearings when producing the wound layer.
  • the press or web guide roll with a non-rotatable support and a roll tube that can be rotated around it, which can be displaced against the support and with supporting elements controllable or controllable supporting force is supported.
  • Almost frictionless running of the roller tube can be achieved with hydrostatic support elements which run on the smooth inner surfaces of the roller tube by means of hydrostatic bearing surfaces and are supported against the carrier with a pressure chamber with a pressure or a controllable or controllable pressure liquid pressure, analogous to that in US 3 802 044 roller described.
  • a web 1 is fed from an input roller 2 via a deflection roller 3a to a web guide roller 4, which centers the web 1 and feeds it with a certain mechanical pretension T via a further deflection roller 3b to a roller arrangement 5, 15, where the web is subjected to a press treatment.
  • a dewatering felt 18 is also passed through the press nip, this being of a hard Roll 5, for example a granite roll and a press roll 15 according to the invention is formed.
  • the press roll and the web guide roll 15 or 4 consist of a light roll pipe 20 or 6 rotatable about an axis 19 or A, for example made of plastic or light metal.
  • This roller tube 20 or 6 is advantageously wound in layers from glass or carbon fiber-reinforced synthetic resin, with which sufficient strength can be achieved even with thin wall thicknesses.
  • a layer 7 of a material with better strength than that of the roller tube 20 or 6 is wound around the outer surface of the roller tube 20 or 6 , advantageously from a wire or tape made of a suitable metal, for example steel or also made of a fiber-reinforced plastic.
  • a single wire or tape winding is generally sufficient to achieve improved abrasion resistance, but several wire or tape layers can also be wound one above the other.
  • the wire winding 7 is oriented almost peripherally.
  • the wire winding 7 can extend in the axial direction, in particular when used as a press roll, over the entire surface of the roll tube 20 or 6 or, in certain applications, can be provided only over part of the outer surface of the roll tube 6, i.e. there may be gaps 16 between the individual winding parts.
  • this is achieved in that, although the central part 7a of the wire winding is oriented peripherally, the windings 7b and 7c on both sides of the center M are inclined by a small acute angle with respect to the circumferential direction one side 7b opposite to the other side 7c.
  • the entire winding is therefore mirror-symmetrical with respect to the center plane M of the roller tube. In this way, the material web can automatically be returned to the center of the roller as soon as it tries to break out laterally in the axial direction.
  • FIG. 4 shows various suitable variants, with smooth surfaces preferably being used for press rolls 15 in order to form a cylindrical roll shape with grooves.
  • a wire layer 7 made of metal wire with a circular cross section is wound on the roller tube 6. Grooves 17 are formed between the adjacent wire windings.
  • the wire winding 7 is somewhat embedded in the still flowable soft surface of the roller tube 6. It is advantageous to condition the wire surface before embedding in such a way that there is an improved adhesion between the wire winding 7 and the roller tube 6.
  • the outer surface of the wire winding 7 is ground, so that a smoother surface is formed than in the previous example, but there are still grooves 17 between the adjacent windings.
  • the cross-section of the wire 7 can also be rectangular or square, which results in different surface ripples Let demand be met.
  • Different trapezoidal, triangular, oval, elliptical or irregular wire cross sections, as shown in FIGS. 4e-k, can also be advantageous depending on the circumstances and the web material to be transported.
  • a suitable band-shaped material can also be used to produce the winding.
  • the wound tape 7 can be designed corrugated, whereby wavy grooves 14 are formed in the circumferential direction on the surface.
  • adjacent tape windings 7 can overlap like roof tiles, whereby the surface of the roller tube 6 is particularly well protected against abrasive and corrosive influences.
  • the material of the wound wire or strip 7 is to be adapted in terms of its mechanical strength and corrosion resistance to the pressing forces and to the web 1 to be transported.
  • Steel is generally sufficient, possibly with special alloy additives, but in special cases the use of hard metal is advantageous or of glass metal, e.g. according to US 4,721,154.
  • the roller tube 6 of the web guide roller can be provided with side end covers 8, which carry the roller journals 9.
  • the roller tube 6 rotates together with the end caps 8 and the pin 9.
