  • Patent number: 5873374
    Abstract: The present invention relates to a cleaning comb with needles that are rugged on their peripheral surface and a method of manufacturing a high mechanical strength cleaning comb. The comb includes a plurality of needles arranged parallel to each other with a spacing of under 100 .mu.m, which are rugged on their peripheral surface for the purpose of more effectively removing foreign elements and smaller particles attached. The needles have a total length and a useful length, i.e. a relatively large portion that protrudes from the handle, and they have a diameter of over 1 mm. In order to give the comb a high mechanical strength, the method of assembling the comb includes attaching the needles onto the handle preferably by laser welding or soft soldering. The ruggedness on the peripheral surface is provided by cutting an helical groove or several parallel circumferential grooves.
