【摘要】 分析了ＧＣ２８８Ｓ倍捻机成形机构的结构和工作原理。成形机构采用等速导丝运动规律的圆柱凸轮使丝线成形，并设计安装有变幅机构和变频机构，前者使卷绕筒子形成双锥度形状，后者起到丝条防叠作用。更多还原

【Abstract】 Analyses the composition and working principle of the building motion of double twister GC288S. The motion consists of builder cam effecting constant speed yarn feed and an amplitude changer with a frequency changer. The former promotes a double-tapered cone, while the latter prevents yarns from overlapping.更多还原
