Abstract : A computerized feedback control system was developed at the pulp insulating stage as a first step to improve the uniformity of the pulp insulation. The objective is to assure a consistent average mutual capacitance of 83 + or - 43 nF/mile and a capacitance deviation of better than 4% particularly for higher pair density type cables. The system consists of a microcomputer controlled diameter scanner and moisture measurement system for each pulp line. Control of oven temperatures and water applicator is effected at a central computer based on average values transmitted by the microcomputer. Better pulp insulation density control is achieved by increased sampling of weight per foot coupled with automatic regulation of pulp flow to each machine as a function of consistency. (Author)
