Abstract: The present invention discloses a burr removing apparatus including a base for placing the compact disc on, and a pressing apparatus equipped on the base and corresponding to the inner circle of the compact disc for moving up and down to eliminate a bur at the inner circle of the compact disc. An upper and a lower inhaling apparatus are respectively equipped in the pressing apparatus and the base, and extend respectively to the surfaces of the pressing apparatus and the base. The upper and lower inhaling apparatus have the upper and lower inhaling holes to inhale the bur eliminated. The present invention eliminates and inhales the redundancy before bonding the discs, so the smoothness of the disc can be improved to avoid the bubbles while bonding, and providing a disc with good mechanical properties and weather-resistance.

Abstract: A method is provided for automatically linking beads or the like, in each of which have a through hole. In this method, a thread having a predetermined length is fastened at one end thereof onto a straight elongated magnetic member and at the other end onto a stationary fixture. A magnetic block is positioned near the elongated magnetic member so that the elongated magnetic member is attracted by the magnetic block in an upward direction, therefore leaving a working space of a desired size between the magnetic block and the elongate magnetic member. The beads or the like ar fed by a feeder into the working space one by one while permitting their through holes to be brought into registry with the free end of the elongated magnetic member. At the time of the registry, the beads or the like will automatically sleeve on the elongated magnetic member and in turn slide downwardly along the thread due to the fact that the elongated magnetic member is attracted in the upward direction.
