<p>The invention relates to an apparatus and a process for feeding papermaking stock to a papermachine. The apparatus comprises a mixing vessel (12) for receiving and mixing stock components and a pipe (40) for feeding the resulting mixed stock to said papermachine. In the feeding pipe (40) there are stock flow metering means (42) stock consistency sensing means (44) and stock flow control means (32). Said means are all connected to a control system (46) adapted for receiving said flow data (Q) and said consistency data (C). The control system (46) is adapted for continuously computing a value for the product (QxC) of said flow and consistency and for providing adjustment of the flow control means (32) to keep said product (QxC) at a target value. The invention provides faster response times in the control of a papermaking process. It also reduces the volume of stock mixing vessels and the amount of water in the process.</p> |
