Abstract
A jet suction method and a jet suction box (14), for a suctioning apparatus (6) of a device (1) for water jet consolidation of a fibrous material web (2), sucks in the liquid jets (4) emitted by the device (1) for water jet consolidation and issuing from the fibrous material web (2) again. A box casing (18) thereof has arranged therein at least one slot shape casing opening (20) which leads to a box interior (17). The jet suction box (14) has on the box casing (18) at least one nozzle attachment (24) which is arranged above the casing opening (20) and which has a slot shape suction opening (25) with a width steadily increasing towards the box interior (17) and towards the casing opening (20). A width of the casing opening (20) is equal to or greater than the outlet-side width of the suction opening (25).
Claims20
A jet suction box for a suction device of a fibrous material web, wherein the jet suction box is intended and configured for suctioning liquid from the fibrous material web, and wherein the jet suction box comprises:
