Method for producing a feeder with a mesh-like fabric covering over the feeder opening thereof

A method for producing a feeder (10) in a core shooter for use in a casting mold used for casting of metals, the feeder that is produced having a feeder body (11), the feeder body enclosing an inner cavity (25) as a feeder volume, the feeder body comprising an exothermic and/or insulating material and having 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 a mold cavity of the casting mold during a casting operation, the method comprising the following steps:

• providing a mesh fabric consisting of a fireproof material for covering over the feeder opening (14) to be produced therein;
• positioning a fabric piece (21) of the mesh fabric in a pattern device (17) of a core box (30) of the core shooter, in such a way that a peripheral region (22) of the fabric piece (21) positioned in the bottom region (13) of the feeder (10) to be produced is at least partially bent up in a direction of the at least one lateral wall region (12) of the feeder body to be produced (11),
• shooting of the feeder (10), wherein the peripheral region (22) is surrounded by material shot in to produce the feeder and is anchored in the material of the feeder (10), and
• wherein the fabric piece (21), is pressed between positioning pins (19) which are arranged on a base plate of the pattern device predetermining the bottom region of the feeder body and which the positioning pins (19) project into the at least one lateral wall region of the subsequently produced feeder body, so that the peripheral region (22) of the fabric piece (21) projecting over an area surrounded by the positioning pins (19) is bent up.
