捻制金属帘线时,在钢丝中所产生的应力,对其耐久性和平直度都带来不良的影响,并导致金属帘线的松散。为消除这种应力,在捻制前对股进行预变形。变形装置需要细心的调整,且在股中存在缺陷时,由于摩擦有时毕竟还会发生股的折断。消除绳丝中的捻制应力,所已知的装置和方法对金属帘线也能采用。其中,也包括在绳索生产中采用重复捻紧一松开的方法。综合应用 When twisting a metal cord, the stress generated in the steel wire adversely affects its durability and flatness, and causes looseness of the metal cord. To eliminate this stress, the strands are pre-deformed prior to twisting. Deformation devices need careful adjustment, and the existence of defects in the stock, due to friction, after all, may also occur after the break of the stock. Elimination of twisting stresses in the cord, known devices and methods are also available for metallic cords. Among them, including the production of rope used in a tight twist a loose method.
