  • Patent number: 4858659
    Abstract: An apparatus for forming and cutting a flat type multi-core cable is disclosed, in which core conductors of a flat type multi-core cable, whose core conductors are previously exposed by exfoliating a part of a jacket therefor, are divided into a plurality of units; the core conductors are formed and cut separately for every unit; and at the same time the pitch of the core conductors is corrected. Further the number and/or the pitch of the core conductors are calculated by using information obtained by the scanning of the core conductors and cables, for which the number of the core conductors is not in agreement with predetermined one, or cables, for which errors in the pitch of the core conductors exceed a certain limit, are excluded as deficiencies.
