padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">为</span>15 mm的孔，放上一个喇叭口两头拧紧（不能漏气）；停车、启动时常会发现积花从锭翼通道掉出，易在粗纱上产生纱疵。为此，在横管部位钻2个直径为10 mm的孔,将前排直径<span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">为</span>10 mm×750 mm的管和后排直径<span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; overflow-wrap: break-word !important;">为</span>10 mm×850 mm的管用胶与所钻孔连接在一起，对准假捻器口部。锭翼肩上常有积花，可将吹风立管加长。保留了上龙筋盖板面吹风口功能。</span></p><p style="margin-bottom: 0px;
