Listarrangemang för en dubbelvira-formare innefattande en dynamisk bäranordning för motlist

摘要

The invention refers to a foil arrangement (33) and a method for a double wire screen former. At least one foil (6) comprises a flexible counter blade (10) extending over the entire screen (3) width. The counter blade (10) is supported on a flexible device (12) mounted on a beam (13) extending in the lateral direction. The flexible device (12) is arranged to apply a flexible pressure on the counter blade (10) such that the counter blade (10) applies a flexible pressure on one of the screens (3). The foil arrangement comprises a dynamic anvil means (19) for dynamically applying a force on the counter blade (10) in the counter direction of the screen (3) movement.
