Abstract

The invention is directed to an exchangeable frame for the shaving head of a dry shaving apparatus, comprising two longitudinal frame members in parallel arrangement and end walls connecting the longitudinal frame members at their respective ends, as well as at least one shaving foil which is carried on inwardly protruding projections provided on the two longitudinal frame members by means of suspension openings and is shaped to an arched twin head shaving foil cutter by means of another longitudinal frame member extending parallel to the two longitudinal frame members and connecting the end walls. A stepped shoulder formed on the projections provides at least one abutment surface and a pin, and the abutment surface is at a predetermined relative distance to the inner wall of the shaving foil slidably resting against the longitudinal frame members. The suspension openings are greater in vertical and horizontal direction than the contours of the projections. Each of the two longitudinal frame members has associated to it a mounting plate extending parallel thereto with openings for receiving the pins, with the mounting plate resting against the abutment surfaces and being attached t…
