Device for cleaning and antistatic treatment

of records

The innovation concerns a device for cleaning and antistatic treatment of records.

The innovation is based on the task of creating a device for handling records that is as simple as possible Way both the mechanical removal of foreign bodies, 2nd, B. Grains of dust and the like from the record surface, as well as the elimination of antistatic phenomena.

The innovation solves this problem according to the teachings contained in the protection claims.

The innovation is shown below using one in the drawing illustrated embodiment described in more detail. In the drawing shows:

Fig. 1 is a side view, partly in axial section;

7617976 12/30/76

Fig. 2 shows a cross section along the line II-II ii Fig. 1j

Fig. 3 shows a cross section along the line III-III in Fig. 1.

Baa device consists of an elongated housing ^ with side walls 2, 3 t end walls 4, 5 and a top wall 6. You end walls A, 5 are provided with holes 7 into which pins 8 engage which are provided at each end of the shaft 9.

They shaft 9 carrying a plate 10, on which two halbzylindrisohe Bo! Impart 12, 11 are attached porous material, such as Sb _a foam plastic · they besitst surface of Boller part a cover 13t, the woven from an antistatic material consists · Si " The surface of the bollard part has a covering 14 made of velvet

The antistatic material of the cover 13 closes preventively a thin yarn in which at least some of the fibers are electrically conductive, e.g. B staple yarn (unequal Lengths), with conductive plastic material. At least two Adjacent fibers ensure a conductive path with good contact and even transverse static Path along two fibers · A yarn which is preferably used is known by the trade name "Brunelon" · Bias yarn is a very fine Hylon steel fiber fabric bit unequal, a few feet long. You stitch threads of the fabric consist of 100% solohem yarn, at least 10% of the open ends would then be made of steel. Fall out the warp threads a bsi relatively low temperature hot melt end Made of such a material as polypropylene, winding or ripping can be avoided, reloading the Boller surface is fused hot.

The velvet covering of the pan part 12 is chosen “dxmit With the open surface of this covering, residues on the surface and in the grooves of the record are physically removed can be.

As can be seen from FIG. 2, the shaft 9 is provided with a flattened part 15 at the end, adjacent to the pin 8. Bas part 15 goes into a keyhole slot 16, which is located on the fastening strap 17. The fastening area 17 is provided with a pin 18, the opening 19 i> the lowest part of a hollow 20 which is formed in the upper wall 6 penetrates. An actuation button 21 is fitted on the pin 18 · A Compression spring 22 urges the button 21 to the fastening tab bring it into its rest position su, the part 15 engaging in the narrower end of the keyhole-like slot 16. The rotation of the roller 11, 12 is thus prevented. Pressing the button 21 with a finger causes the fastening area to be shifted downwards, whereby the part 15 is then located in the further end of the slot 16, in which it can rotate freely.

The device is preferably indicated with a Söhnapp lid 25 in Fig. 2 and 3 bit dash-dotted lines - provided which with an adjustment flange or with a tongue (not shown) is equipped, which (which) can be used in the slots 24 of the side walls 2, 5.

In use, the device can be easily grasped by means of a corrugation 25. The desired roller surface 13 or 14 can be brought into an exposed position by pushing the roller 11, 12 after triggering by pressing the button 21 is rotated. The rotation can be effected by physical contact with the surface of a rotating record will.
