Definitions

  • the invention relates to a roller for the coating or the application of ink on tapes, in particular metal tapes in tape coating or tape printing systems, which roller has a rigid base body on which an elastic layer, preferably made of rubber or plastic, is applied.
  • rollers have been known for a long time.
  • DE-A-35 25 045 has disclosed such a roll of the type mentioned at the outset, in which the rigid body consists of a plastic reinforced with carbon fibers, to which an elastic layer of rubber or plastic is applied.
  • These known rollers which are designed to be elastic on their circumference, can ensure a uniformly thick coating application over the entire width of the strip to be coated, even if the base body undergoes a certain deflection despite its rigid construction or if the strip to be coated has its entire cross-section tape is not absolutely uniform. This is achieved in that the elastic layer of the roller can flatten when it is pressed against the strip to be coated.
  • These known rollers can also be used as a so-called impression roller opposite a coating roller made of metal or the like, where they are cause the uneven strip to nestle against the coating roller due to its elasticity.
  • rollers in coating devices equipped with an elastic surface have the disadvantage that they do not have sufficient resistance to chemicals, e.g. the solvents, acids or bases contained in paints or cleaning agents, as well as very susceptible to mechanical damage, e.g. through sharp band edges.
  • the invention is therefore based on the object to design rollers of the type mentioned in such a way that their elastic layer, which enables the flattening of the roller surface, is adequately protected against destruction by solvents, acids and / or alkalis and mechanical influences without their elasticity or resilience significantly affect.
  • This object is achieved according to the invention in that the elastic layer of the roller has a thin, flexible metal coating on its outside. This metal coating protects the roller on its surface against chemical or mechanical damage, but is on the other hand so flexible that the roller can nestle with its surface on uneven strip surfaces with more or less flattening of its circumference.
  • the roller can be adjusted to the required conditions.
  • the elastic layer can consist of a more elastic or less elastic material, for example of a softer or a harder rubber or plastic, depending on the requirements.
  • unreinforced plastic so chosen one that is free of reinforcement or stiffening inserts.
  • An adaptation of the elasticity of the roller surface to the desired requirements can also be achieved in that there are cavities within the elastic layer, which are connected or can be connected to a pneumatic or hydraulic pressure source and can be pressurized via this source. This enables a continuous adjustment of the elastic layer of the roller to the desired layer hardness.
  • the metal jacket preferably has a wall thickness of 0.1 to 1.0 mm and can e.g. made of chrome, nickel or stainless steel.
  • the elastic layer can have a thickness of 5 to 70 mm, preferably 15 to 30 mm.
  • a roller for printing presses is also known, the essentially rigid base body of which is provided with a coating of ceramic or metal.
  • This roller should be subject to the least possible deflection with a light weight and also has a low elasticity on its surface due to the lack of an elastic layer on the roller circumference. It is therefore not in a position to guarantee a coating application that is uniformly thick over the entire range in coil coating systems.
  • the invention also relates to a method for applying the metallic coating in the form of a metal jacket to the elastic layer of the roller.
  • a method for applying the metallic coating in the form of a metal jacket to the elastic layer of the roller according to the invention, in this process, before the metal jacket is applied first the elastic layer is cooled and the metal jacket is heated. During the subsequent temperature equalization, the metal jacket presses onto the elastic layer and thus receives a coordinated shrink fit on this layer.
  • connection between the sheath and elastic layer can also be done by gluing using an elastic adhesive.
  • the roller shown in longitudinal section has a base body 1 made of a rigid steel tube, which is seated at its ends via hubs 2 on axle stubs 3.
  • an elastic layer 4 made of rubber or plastic is applied, which has a thin, flexible metal coating 5 on its outside.
  • This metal coating is formed by a metal jacket which is applied to the elastic layer with a shrink fit. Due to the thin, flexible metal coating 5, the roller described is able to nestle over its entire axial length on uneven surfaces of strips to be coated, in order to thereby ensure a coating application which is uniformly thick over the entire range.
  • roller according to the invention Another advantage of the roller according to the invention is that its metal coating can be provided with a grid or other profiling according to the use of the roller, and its surface hardness can be adjusted according to the respective requirements with the aid of thin-layer or thick-layer technology. Coatings, for example with ceramic or titanium nitride, or other surface treatments are also suitable here.
  • the roller according to the invention can be used not only in belt systems, but also wherever rollers or rollers with elastic or resilient surfaces are required which are subject to wear or chemical attack.
  • the roller according to the invention can be used as an impression roller, squeeze roller, as an immersion roller in belt treatment plants, as a damping roller or as a wear-protected “soft” roller in coil coating or printing processes.
