PAPER MACHINE WET FORMING SECTION AND METHOD OF OPERATION THEREOF |
摘要 |
PAPER MACHINE WET FORMING SECTION AND METHOD OF OPERATION THEREOF In order to independently influence the dewatering performance of a wet forming section of a paper machine as well as the quality of a web produced by the machine, a paper machine head box is mounted on a swiveling device adapted to move a nozzle of the head box around a periphery of a forming cylinder. Two continuous-loop forming wires wrap about the forming cylinder and pulp is discharged through the nozzle into a gap formed by the two wires. A method of operation of the wet forming section includes the step of swiveling both the head box nozzle and an inlet roll (upon which one of the wires is wrapped) around the forming cylinder in a circular arc.
