1. A tool (W) for production of a fiber/foam composite in which a fiber material is embedded into the fiber/foam composite comprising a housing (1) having
at least one first inlet opening (E1) and at least one second inlet opening (E2),
one or more first outlet openings (A1), at least one second outlet opening (A2) and at least one third outlet opening (A3) and
a first side (9) having a width (B),
where
the first outlet opening (A1), the second outlet opening (A2) and the third outlet opening (A3) are arranged on the first side (9) of the housing (1) and where
the first outlet opening (A1) is connected to the first inlet opening (E1),
wherein
the second outlet opening (A2) and the third outlet opening (A3) are connected to one another by the second inlet opening (E2) via a multiway distributor (6) and
the second outlet opening (A2) and the third outlet opening (A3) alternate with the first outlet opening (A1) at least over part of the width (B) of the first side (9),
wherein there is at least one mold (8) in the connection between the first inlet opening (E1) and the first outlet opening (A1),
wherein the first outlet opening (A1) is configured to extrude the fiber material,
and wherein the first outlet opening (A1) runs in a zigzag and the second outlet opening (A2) is disposed above an upper edge of the first outlet opening (A1) and the third outlet opening (A3) is disposed below a lower edge of the first outlet opening (A1).
