FIELD: process engineering.
SUBSTANCE: invention relates to machine building and may be used for twisting bars into rope at lathes. Proposed method consists in drawing bars through decelerating assembly and guiding assembly, jointing them together, securing in fastening assembly and twisting. Note here that decelerating assembly and guiding assembly are mounted on lathe slide. Securing assembly is arranged in lathe chuck. Bars are twisted on revolving the chuck and slide feed equal to rope bar screw line pitch per one revolution of chuck. Device comprises bar decelerating assembly, guiding unit with bar drawing channels, joint assembly, bar securing and twisting assemblies. Said decelerating assembly, and guiding unit are equipped with means to mount them on lathe slide while bar securing unit allows its mounting in lathe chuck to make twisting assembly.
EFFECT: production of twisted rope at lathe with no modification of lathe.
