Cover strip-off method in a covered wire cutting and stripping apparatus

摘要

A cover at an end portion of a covered wire is incised by upper and lower cutting blades. The covered wire and the cutting blades are moved relatively in the longitudinal direction of the covered wire to thereby start the cover stripping operation at an end portion of the cover on the core. Thereafter, during this relative movement, the depth of incising the cover by the cutting blades is reduced step by step within a range where blade portions of the cutting blades can catch the cover. Even in the case where the cover of a covered wire is thin, it is made possible not only to strip the cover surely, but also to prevent a core from being injured.
