Patent
CA 2378125
The present invention relates to a method for producing and testing a fiber bed (39), includes a housing (12), a maim 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 means (40) for measuring properties of the fiber bed. The method is characterised in positioning said body 30 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 fiber 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. The present invention also relates to a device for performing the method of the invention. (Fig.1)
