Definitions

  • the invention relates to a contact roller for a winding machine for winding web material made of plastic, wherein the contact roller has a support tube and a coating applied to the outer circumference of the support tube coating.
  • So-called contact winder for winding continuous plastic web material, such as film or nonwoven webs, in which a contact roller and a winding shaft rotating by friction drive are provided, on which the tapered web is continuously wound into a coil, are widely known. It is only an example of this DE 42 13 712 C2 directed.
  • the known from the prior art contact rollers have, depending on the application, a metallic, usually chrome-plated or plasma-coated hard surface or are coated with a coating based on a natural or synthetic rubber, i. provided with a so-called rubber coating, which may either have a smooth or a groove-shaped recesses formed surface.
  • the gumming used gives such a trained contact roller a certain elasticity, so that between the contact roller and the adjacent winding shaft a desired contact pressure can be adjusted.
  • the known contact rollers only come into contact with the radially highest points of the winding shaft or of the coils of the wound web material formed thereon. Due to the usual large axial length of contact rollers of at least 1,000, often more than 3,000 mm, they must have a high intrinsic stiffness and are usually not capable of inevitably z. B. due to thickness errors and deflections of the winding shaft resulting non-uniform surface of the coil to follow.
  • the object of the invention is to develop a contact roller of the type mentioned so that they can also follow non-uniform surfaces of forming on a winding shaft coils of a wound web material with high compliance and elasticity and beyond should also have vibration damping properties.
  • the inventive proposal provides to build the contact roller in the manner of a "sandwich construction" by the coating is formed multi-layered and at least one inner applied to the support tube inner layer and an outer side applied to the inner layer outer layer, which at the same time the outer surface of the Forming contact roller, wherein the inner layer is highly elastic with a lower hardness than the outer layer is formed.
  • the inner layer is due to its low. Hardness very resilient and elastic and has good damping properties, with these properties can be varied by the skilled person depending on the application by varying their thickness and their structure.
  • the soft inner layer is compared to the inner layer significantly harder, preferably dense and low-wear outer layer applied, which is also mechanically well machined to obtain, for example, by grinding an exactly cylindrical surface or to bring in desired groove or groove profiling can.
  • the inner layer of a soft elastic material having a Shore A hardness of 2 to 30 is formed, while the outer layer of a material having a Shore A hardness of 40 to 90 is formed. It is further preferred that the inner layer and / or the outer layer is formed on the basis of natural or synthetic rubbers, which can be easily adjusted by appropriate formulation of the rubber mixture used, the desired Shore hardnesses.
  • the inner layer is foamed, i. it has a preferably predominantly closed-cell foam structure with an average cell size of 0.05 to 1.0 mm.
  • the gas bubbles embedded in the inner layer to this extent increase the resilience and elasticity and damping properties of the inner layer again and also impart an extremely low weight, so that the dead weight of the contact roller according to the invention and thus also its deflection can be limited at a large axial length.
  • the respective layer thicknesses of the inner and outer layer depend on the requirements of the particular application and on the axial length of the contact roller, which in turn is dependent on the width of the incoming web material to be wound up. Typical thickness ranges are in the range of 5 to 30 mm for the inner layer and in the range of 0.5 to 5 mm for the outer layer. The choice of larger thicknesses for the inner layer gives This higher elasticity and flexibility and improves their damping properties.
  • the inner layer and the outer layer and / or the inner layer and the carrier tube can be connected to one another by means of a suitable adhesion-promoting layer or else be arranged on top of each other by other suitable methods, for example shrink-fitting and the like.
  • the support tube of the contact roller according to the invention is usually formed of steel, aluminum or carbon fiber reinforced plastic (CFRP), but of course other materials can be selected by the skilled person as needed.
  • CFRP carbon fiber reinforced plastic
  • Such a previously described contact roller is particularly suitable for use in a winding machine for winding continuously tapered sheet material made of plastic, such as a film web or nonwoven web.
  • the single figure shows a contact roller 1, as used for example in a winding machine for winding continuously tapered sheet material made of plastic, such as a film or nonwoven web.
  • a winding machine for winding continuously tapered sheet material made of plastic, such as a film or nonwoven web.
  • the function of such a winding machine is for example from the DE 42 13 712 C2 can be seen, the disclosure of which is expressly included here.
  • the contact roller 1 consists of a support tube 10, for example made of steel d3 of 8 mm and has on both sides of the stub axle 12, by means of which they in a manner not shown via pivot bearings in the winding machine stored and optionally provided with a drive, such as a rotary drive.
  • a coating 11 is applied, which in turn is formed multi-layered.
  • an inner layer 110 of a soft elastic natural or synthetic rubber of thickness d2 of 5 to 30 mm with a Shore A hardness of 2 to 30 is first applied. If necessary, a connection between the metallic carrier tube 10 and the inner layer 110 can be effected via a suitable adhesion-promoting layer 111 located therebetween.
  • the inner layer is foam-like and contains embedded gas bubbles of predominantly closed-cell shape with an average cell diameter of e.g. 0.3 mm.
  • the inner layer is due to their low Shore hardness and their embedded gas bubbles extremely yielding, elastic, lightweight and has good damping properties that can be varied by varying their thickness d2.
  • an outer layer 112 which consists of a relation to the inner layer significantly harder material, preferably a natural or synthetic rubber having a Shore A hardness of 40 to 90.
  • This outer layer 112 is dense, low-wear, hard, easily machinable and forms the surface of the contact roller 1, which also comes into contact with the respective wound web material.
  • the outer layer 112 preferably has a thickness d1 of about 3 mm.
  • the outer layer 112 can be ground, for example, to obtain a particularly smooth surface or provided with groove-shaped profiles, if this is necessary for the particular application.
  • the coating 11 is able to follow also non-uniform surface course of the coil of the already wound web material, which optionally bears against the contact roller with a certain contact pressure.
  • the contact roller is able to adapt to the non-uniform coil on the surface ideal.
