Abstract (en)
[origin: WO2017157788A1] A method for producing a feeder (10) that is intended for use in a casting mould used for the casting of metals and comprises a feeder body (11), which encloses an inner cavity (25) as a feeder volume, consists of an exothermic and/or insulating material, has at least one lateral wall region (12) and a bottom region (13) with a feeder opening (14) arranged therein for connecting the inner cavity (25) of the feeder body (11) to the mould cavity of the casting mould during the casting operation and has a mesh-like fabric consisting of a refractory material covering over the feeder opening (14) thereof, is characterized in that, in the course of the production of the feeder in a core shooter, a piece of fabric (21) of the mesh-like fabric is positioned in a pattern device (17), forming the shape of the feeder (10) in a core box (30) of the core shooter, in such a way that the peripheral region (22) of the piece of fabric (21) positioned in the bottom region (13) of the later feeder (10) is at least partially bent up in the direction of the lateral wall region (13) of the feeder body (11) and, during the shooting of the feeder (10), the bent-up peripheral region (22) is surrounded by the material shot in and is anchored in the material of the finished shot feeder (10).
