DEVICE TO TWISTING OF COMPOSITE REINFORCEMENTS CORE AND COMPOSITE REINFORCEMENTS PRODUCTION LINE WITH SAID DEVICE Russian patent published in 2014 - IPC E04C5/07 

FIELD: process engineering.

SUBSTANCE: invention relates to production of construction materials. Line for production of composite reinforcement with bearing core and helical winding from roving threads impregnated with thermosetting binder comprises bobbin carrier with reels with roving threads, said winding being composed of bundles and/or tapes of winding roving. It comprises also, the roving pre-drying assembly and impregnation bath with stretching and squeezing devices. Forming assembly includes helical winding device and heating assembly. Besides it comprises pull and-cut assemblies, and at least one device to twist the core from roving threads arranged ahead of forming assembly. Said twisting device comprises bed, drive, roving threads bobbin, bobbin drive, twisted core guide flute and clamp to stretch twisted core and to direct it at roving thread bundle in the bearing core of composite reinforcement.

EFFECT: higher efficiency.
