Abstract: PURPOSE: To produce a mixture be preparation precisely in a short time by measuring components successively by means of an electronic differential weighting machine which has a screw conveyor and supplying the components successively into a two axes screw extruding machine, and forming plastic rod-like material. CONSTITUTION: A copolymer, e.g. stearyl alcohol and theophylline, is measured with a weighing machine that uses three microprocessors technology, supplied into a hopper of an extruding machine and extruded. The temperature of a cylinder of the extruding machine in six processes shall be 30, 60, 60, 60, 60, and 60 deg.C respectively and an extruding die is heated at 100 deg.C. The obtained rod-like material is directly compressed into rectangular tables. The new successive measurement provides more uniform weighting than that achieved by conventional non-successive weighing. Because the successive measurement is done at the preparation production site directly, all the possibility of the separation is removed.
