摘要：
A touchless air cleansing system is provided for the stripper shoe or shoes of a concrete product producing machine comprising an air knife mounted on the feed box and having a nozzle supported in facing spaced relation to the underside surface of the shoe when the shoe is in the raised position. The air knife is operative during movement of the feed box for directing a moving curtain of high pressure air against the underside surface to cleanse it of any latent moldable block material that may have accumulated on its underside surface.
