Abstract: A needle device for processing an in particular strip-shaped planar structure comprises a needle bed, on which a plurality of needle elements provided with tips are arranged in such a manner that the needle elements protrude from the needle bed and the tips thereof point away from the needle bed. The needle elements are designed as flat blades each of which having at least one cutting edge extending from the tip of the needle element toward the needle roller. The needle elements are fastened via leg-shaped mounting members in bar-like needle carriers, which are in turn inserted in grooves of the needle roller.

Abstract: A device (10) for removing a tattoo comprises a tattoo machine tip (14) and a tattoo machine (12). The tattoo machine tip (12) comprises a tip body (28) that comprises a needle channel (32) for guiding at least one tattooing needle (34). Said tip body (28) is connected with a supply container (50) for receiving a liquid. According to the invention, said supply container (50) is filled with a skin irritant (52). Further, said supply container (50) is connected through a feed channel for wetting the tattooing needle (34) with said skin irritant (52) with said needle channel (32), wherein said feed channel (54) opens out into said needle channel (32). Unnecessary dead volumes are avoided thereby, so that the consumption of skin irritant is minimized.
