Abstract:
1. Method for producing and testing a fiber bed ( 39 ), includes a housing ( 12 ), a main inlet passage ( 14 ) and a main outlet passage ( 16 ), a cavity ( 18 ) in said housing in fluid connection with said inlet and outlet passages, a body ( 20 ) rotatably arranged in said cavity, said body being arranged with a through-going passage ( 24 ) having a first and a second opening, a screen ( 25 ) arranged in said through-going passage and adjacent to the second opening, and means ( 40 ) far measuring properties of the fiber bed, characterised in positioning said body so that the first opening is connected to the main inlet and the second opening is connected to the main outlet, creating a first passage, leading a first suspension through the first passage in order to produce a fiber bed on the screen, measuring the properties of the bed, rotating said body such that the second opening is connected to the main inlet and the first opening is connected to the main outlet and creating a flow through the first passage for removing said fiber bed from the screen through the outlet.
