Abstract: A slatted apron for covering movable tool machine parts includes a multiplicity of links connected in an articulated manner which present a major surface presenting a cover surface portion and subsequent lateral surfaces. In this slatted apron, or the links are arranged, in an extended position wherein they are aligned along a straight line, in such a way that portions of their lateral surfaces are closely adjacent. Hereby matter such as, for example, chips may be prevented form getting into a zone between links to become jammed or wedged and, e.g. cause damage to the slatted apron.
