Abstract:
     This invention provides a closed-loop ratio control system which can be used to maintain certain proportional relationship between the instantaneous flow rates of the core and surface shavings, the instantaneous flow rates of the core and surface adhesive agent, as well as the instantaneous flow rates of the core and surface firming agent. Said system is not only suitable for keeping certain ratio between the shavings, adhesive agent, and firming agent in different layers, and tracing their variations, but also stabilizing substantially the total flow rates of the shavings applied with the glue.
