A liner protects an interior surface of a chute that transfers workable foundry molding mix from a mixer to a machine for molding and hardening. The liner has an upper border portion and body portion. The upper border portion secures the liner to an upper portion of the chute. The body portion has at least one panel of a flexible material and is sized and adapted to line the interior surface of the chute. The liner also has a plurality of apertures through the upper border portion for attaching the upper border portion to the upper portion of the chute. The flexible material of the body portion is a woven fabric with polymeric fibers and, optionally, a polymeric coating.
