The present disclosure relates to a vacuum dewatering apparatus comprising a vacuum box disposed opposite of a steam box where the steam box comprises a bottom plate having a substantially linear portion and a curvilinear portion. A plurality of apertures are disposed along at least a portion of the curvilinear portion to permit the transmission of steam. In a preferred embodiment, the curvilinear portion is adjacent to the trailing edge and the linear portion is adjacent to the leading edge of the apertured bottom plate. Further, at least a portion of the apertures are aligned opposite the vacuum box which acts to remove the steam. The vacuum dewatering apparatus of the present invention enables the use of high levels of steam improving vacuum dewatering and improving drying efficiency.

Fibrous web dewatering apparatus and method

A device for controlling web tension is disclosed. The device includes a carriage in which a first guide roller is spaced from a second guide roller by a frame. The carriage or frame pivots about a pivot location. A moving web is threaded through the carriage in a serpentine path. Rotation of the carriage or frame causes web displacement. When tension disturbances occur in the moving web, the device rotates for accumulating or releasing the web material and thereby dampening tension variations downstream. The pivot dancer device can be placed in a communication with a controller for open loop control or closed loop feedback control.
