The free find this ;, swivel arm 7 carries a downwardly directed cutting stylus 8 which dips into the Plauenmalerial and separates ilen pinched edge 9 \ nn the record. It is therefore advisable to only select the cutting stylus 8 for rotation, that is to say when the motor is switched on. to allow penetration into the plate material. For this purpose \ orgeseheii. the suction plate 6 and danii'i to lift the record somewhat during the rotary movement of the cutting stitch, ie to move it in the direction of the cutting stylus.

In the pinch- edging cutting device according to FIG. 2, the swivel arm 11 carrying the cutting stylus 10 is attached to the lower end of a hollow cylinder axis 12, which is rotatably held in a vertical position in a holder designed as a slide 13. The upper end of this hollow cylinder axis 12 also protrudes from the holder and is rigidly connected to a gear 14 there. A tube 15 is guided through the inner bore of the hollow cylinder axis, at the lower end of which a suction plate 16, equipped on its underside with suction devices for holding the record in place, is attached. Here, too, the suction devices are connected to an evacuation device via a hose guided through the pipe 15. The spatial assignment of the cutting stylus 10, swivel arm 11 and suction plate 16 is identical to that from FIG. 1 (cutting stylus 8, swivel arm 7 and suction plate 6). The toothed wheel 4 is in engagement with a toothed rack 17 in such a way that when the slide 13 is moved along the toothed rack 17, the toothed wheel 14 rolls on the toothed rack 17, with tier _m i _t J _0n -. The toothed wheel 14 encircles the record and separates the pinch edge IS from the record.

This on a sledge arranged device has the main advantage that for the circular movement of the cutting stylus 10 no special drive device is required. In addition, there is one trained in this way Device their preferred application in automatic record pressing devices where the individual manufacturing processes run along a horizontal production line. Appropriately you will arrange the carriage here transversely to the production line direction, so that the pinch edge 18 may fall into a container off the production line.
