【摘要】 HY742型倍捻机是一种用于双股或多股纱线加捻的微电脑控制多电机倍捻机。采用摩擦辊变速使锥形筒管实现恒线速卷绕,从而使纱线的各片段的捻度不匀得到控制,将横动机构中变速的曲柄圆周运动变成匀速的往复直线运动,卷绕成形好。介绍了HY742型短纤倍捻机的性能特点及生产使用情况。更多还原

【Abstract】 HY742 double twister is using in double-ply and manifold yarn twisting, it is multi-motor double twister which controlled by microcomputer. Cone bobbin can realize constant linear velocity winding by adopted friction roller changing velocity, so twist irregularity of each fraction can be controlled, and winding shaping is better if taking uniform reciprocating motion instead of change clank circular motion in traverse mechanism. Performance speciality and using condition of HY742 short fiber double twister is also introduced.更多还原
