As shown in Figures 1 and 2, the cleaning toriohtung for the turntable cartridge has a disk-shaped * support member Io ₉ which can generally correspond to the dimensions of standard long-playing records for 33 1/3 rev / min. The Seheibe is provided with a central holding hole and can also have a Synehronisatlonsloeh 14, if in connection with the in the aforementioned patent application? 16 22 131 * 1 described device is used. On the circumference of the disc there is a needle cleaning material 16, which allows for a larger, annular surface, which extends from the circumference to the inside.

The material has the shape of a pile or bristle-like fabric, the wake-up call one by pressure adhesive carrier plate can be attached to the disc. The main requirement for the material is that it is the needle allows sish to move freely across the material without the in doing so, the needle or the material is damaged. Though hylon bristles got good results, let's see aaeh instead use other ready-to-use materials.
