ABSTRACT:
In a linked bar member-type apron arrangement for protecting guide tracks, drive assemblies, positions which are liable to accident, or the like, in machine tools or the like, the bar or plate members are each connected together by individual bendable elements which are each secured to the two adjoining plate or bar members. The fixing is preferably made by form-lockingly connecting the bar members to the bendable elements. The bar members preferably comprise extruded aluminium members and the bendable elements preferably comprise extruded polyurethane members. The apron arrangement is easy and inexpensive to produce, extremely durable, easy to handle and highly bendable.
