Electrical marking head for scratch-type embossing machine, has adjusting device with shaft, knurl and/or head and axle to fix relative position of embossing head opposite material surface in initial position and in scratching position

摘要

The head (1) has an embossing head (2) movable perpendicular to a material surface by an adjusting device. A hard metal needle (16) is displaceable in a longitudinal direction opposite the coining head, where the needle and the embossing head are coupled with one another by a pressure spring (20). The adjusting device has a shaft (6), knurl and/or head (7) and an axle (8) for mechanically fixing the relative position of the coining head opposite the material surface in an initial position and in a scratching position, in which a tip of the needle stays in engagement with the surface.
