Abstract
At least one longitudinal baffle extends from an area within the forming zone into the compaction zone. In the forming zone the baffle is pivotally connected to the vat and also has a pivotal structure in the area where the forming zone changes into the compaction zone. Actuating means are located in the compaction zone and apply actuating forces against the outside surface of the baffle to cause the baffle to automatically adjust the convergence angle in response to changes in pulp mat thickness.
