Definitions

  • the present invention relates to a roller and more particularly to a roller for a roller towel dispenser mechanism.
  • a towel is arranged to pass between two rollers and to be moved by means of a mechanism for rotating one or both of the rollers.
  • To provide a driving engagement between the towel and the surfaces of the rollers it is known to provide a frictional covering for the roller surfaces by bonding thereto a pre-cut, waterproof, paper-backed emery strip by means of a solvent-based or other adhesive. The strip is wound spirally onto the roller.
  • a disadvantage of the above arrangement is that the quality of and, in particular, the degree of friction provided by commercially-available emery strips is variable. Accordingly some emery strips do not provide a satisfactory grip on the towel. In addition a problem arises in applying waterproof, paper backed emery strips in that if these are not very well coated, the corners can start to lift, thereby necessitating rejection in the field.
  • the present invention seeks to overcome or reduce at least one of the above problems.
  • a method of providing a roller with a frictional coating characterised in that the roller is coated with an adhesive or varnish material and a coating of particulate material is then applied.
  • a further coating of an adhesive or varnish material is then applied, and the coating is cured.
  • Preferred materials are a two part epoxy varnish and a carborundum grit.
  • a roller having a frictional coating characterised in that the roller comprises a particulate material bonded to the surface of the roller by means of an adhesive or varnish material.
  • An advantage of a roller in accordance with the invention is that a firm frictional drive may be imparted to a web passing over the roller.
  • the frictional properties of the roller are more consistent than with existing rollers. Furthermore the problems of the coating lifting off from the roller are avoided.
  • the roller is preferably for use in a roller towel dispenser mechanism.
  • a carborundum grit is bonded directly to the surface of-a plastics or steel roller by the following method.
  • the above-described embodiment provides a roller with a coating which can firmly drive a towel engaging its surface.
  • the frictional properties of the coated roller are more consistent than with conventional frictional rollers.
  • the coating may be applied to the driving and/or take- up rollers of a towel dispenser mechanism, and can be applied to one or both rollers of each pair.
  • any suitable varnish or adhesive may be used and different materials may be used for the initial and final coatings.
  • any suitable grit or other particulate material may be used as well as or in addition to carborundum grit.
  • the preferred size used is 60 grit, but the range can be from 40 to 80.
  • the roller may be used to drive webs or sheets of other materials, including paper, in a wide range of applications.
