F1/1a型粗纱机落纱成形电路改造

Circuit Innovation of Doffing & Shaping of F1/1a Roving Machine

由于F1/1a型粗纱机采用竖锭结构,各落纱的定长有较大的差异,为了有效减少粗纱头的产生,采用简单的继电器对F1/1a型粗纱机落纱成形电路进行了改造,在尽量减少粗纱头的同时又能使粗纱机落纱位置保持不变,同时换向开关的寿命也得到延长。

For upright spindle structure of F1/1a roving machine and difference of doffing length, innovation in circuit of doffing ＆ shaping of F1/1a roving machine with combination of relays was done to reduce roving waste. This innovation is not only reducing roving waste, but also guaranteeing doffing position, and service life of reverse switch can be prolonged.
