ABSTRACT:
One or more projections are formed, and insulation is stripped, at interconnection areas along one or more conductors, e.g., plural conductive paths in a flat flexible cable, employing apparatus which comprises three rotary members. One or more protuberances on a first rotary member cooperate with a compliant backing surface on a second rotary member so as to form a projection in a conductor about each protuberance. Continued rotation of the first rotary member brings the insulation on each projection into contact with an abrasive surface on the third rotary member, while the protuberance on the first rotary member, about which the projection has been formed, serves as a backing surface to maintain the shape of the projection as the insulation is removed by the abrasive surface.
