  • This sleeve blank 1 is in known, not shown, clamped in a machine, which enables this sleeve blank with constant, adjustable rotation speed rotates.
  • a microdosing system 2 is also installed in this machine. This microdosing system 2 enables an adhesive of one Container 3 is conveyed into a nozzle head 4, which drops the adhesive in drops outputs from an outlet nozzle 5.
  • Such microdosing systems are known and usually work with a piezoelectric head which the droplets are expelled.
  • microdosing systems allow the ejection of drops of adhesive depending on the diameter the nozzle has a diameter in the range from 30 micrometers to 100 Microns.
  • the ejection frequency of droplets from this Microdosing system is a maximum of 2000 droplets per second. This frequency is adjustable, usually with a frequency of about 500 to 1000 droplets worked per second.
  • This microdosing system 2 is so on the machine, not shown arranged that the outlet nozzle 5 in the direction of the axis of rotation of the sleeve blank. At the same time, this outlet nozzle also in the other two directions perpendicular to each other traversable.
  • the microdosing system 2 is set so that the distance the outlet nozzle 5 from the sleeve blank 1 is approximately 0.5 mm, the microdosing system 2 is moved along the axis of rotation of the sleeve blank 1, during which the drops of adhesive are dispensed. This will these drops of adhesive at a constant distance from each other on the surface of the sleeve blank 1 applied. With appropriate monitoring equipment the dispensing of droplets of glue can be controlled so that this only takes place when the sleeve blank 1 is located under the outlet nozzle 5.
  • the droplet dispensing can be done in a wide variety of ways Apply structures to the carrier 1, which in the present case is a sleeve blank is trained.
  • the hard material particles for example by means of a Vibrating table, not shown, scattered. These hard particles can Example be CBN or diamond.
