Abstract: A method for separating beads from a strand of plastic glass, which emerges continuously from a storage unit, wherein the glass strand passes a periodically controllable glass cutter, and the beads are separated from the glass strand in cutting phases. The separated beads are received by molds which are displaced beneath the glass cutter at a timed rate of conveyance, which is adapted to a cutting sequence of the glass cutter, an emerging speed of the glass strand and a desired size of bead. The control of the glass cutter includes, in the periods, two different cutting phases for alternately separating useful beads and waste beads, and the waste beads are easily discharged between the conveyed molds.

Abstract: The invention relates to an energy supply device of a melting tank. According to the invention, between an electrode plane of the melting tank and a converter for the current supply of the electrode plane, a separatable plug connection is provided in the supply line, between the electrode plane and the converter. Thereby in case of a defect of the converter, the supply line can be cut off simply and rapidly, and the converter either tended to or replaced. In an especially advantageous form of execution the energy supply device has a reserve converter so that, on failing of the converter, by unplugging the plug connection and replugging it so as to set up a plug connection to the reserve converter, the energy feed to the electrode plane can be restored within the shortest possible time.
