ABSTRACT OF THE DISCLOSURE An apparatus is disclosed for producing foam from two or more flowable chemical components where a filler material, such as waste foam, is added to one or more of the components prior to mixing and foaming. The charging mechanism for mixing the filler and component comprises a component feed pipe and a filler feed screw having a tubular housing. The discharge opening of the feed screw projects axially into the feed pipe so as to form an annular slot between the feed pipe and the housing to which slot the pipe from the dosing pump is connected, one end of the feed pipe being sealed to the housing.
