Zusammenfassung: | The beads of ABS resin are moulded to have thread holes of a socket form for receiving a piece of silicon rubber tube to be confined after insertion by sqeezing the receiving mouth, which is originally a little upraised from the normal surface for the purpose. When the beads are threaded after surface coating, the elasticity of the rubber tube in the thread hole acts to hold te beads in position on the thread for any arrangement of beads for necklaces. |
