&nbsp; 一、折入边装置的作用</p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp; &nbsp; 折入边装置是织机的一种附属装置,用于剑杆、片梭或喷气织机等无梭织机上,织造出光边织物。因无梭织机采用机外供纬,纬纱筒子位于织口外的静止部位,纬纱被纬纱剪刀剪断,有一小段的纬纱头露在布边外,成为毛边布。安装折入边装置后,能用钩针将露在布边外的纬纱头钩入织口,再通过织机的打纬动作,将纬纱头织入布边内,形成整齐的光边,使面料外观舒适漂亮,提高织物档次。折入边装置常用于高档织物的织造,精毛纺行业运用最多。</p><p style="max-inline-size: 100%;

outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp; &nbsp; 二、应具备的条件</p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp; &nbsp; (1)折入边装置本身没有动力源,其动力来源于织机,一般利用织机上的纬纱剪刀轴,通过齿轮、同步带、联轴器、万向节等来传递动力,但一般不使用链传动。这是因为折入边的运动规律要求与钢筘的运动规律紧密配合,以避让钢筘,防止碰撞。而链传动瞬时传动比是不恒定的,不能保证折入边和织机的完全同步,某些时段会有碰撞的危险,故常规情况下不采用链传动。</p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp; &nbsp; (2)折入边应与织机保持同步运动,确保织造主轴转动一圈,折入边装置也能将上一纬的纬纱头钩入织口中,完成一次折入动作。目前所有的折入边与织机的转速比都是1∶1。</p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp; &nbsp; (3)织机的胸梁上应预留有折入边装置的安装位置,确保折入边能在与织口的前后、高低方向达到相应的位置,同时在门幅方向可调,并能牢固连接,保证开车时不产生较大的震动。</p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp; &nbsp; (4)折入边装置自带有剪刀,要伸出去剪断纬纱,因此织机的托布板应为活动式,可调节长度,每次织造时都调到正好与门幅宽度一致,这样不会阻碍折入边的动作。织机在没安装折入边时,托布板有固定式(一整根)的,也有活动式(几根拼接)的,装折入边后必须改为活动式的。</p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp; &nbsp; (5)纬纱剪刀的形式必须与折入边装置相配合。纬纱剪刀应向引纬侧折入边方向弯曲,以缩短纬纱剪刀与引纬侧折入边所带剪刀之间的距离,而这段距离就是废边的宽度。也就是说,纬纱剪刀弯曲后可提高纬纱利用率,可见图3-1。</p><p style="max-inline-size: 100%;

margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important;

&nbsp; (7)织机所用独立废边装置多种式样,有固定在织机胸梁上的,也有安装于综框前的。折入边安装后,占据了胸梁上的位置,原固定在织机胸梁上的独立废边将没有位置安装。所以要使用折入边,就只能使用安装于综框前的独立废边装置,或要对原独立废边重新进行设计改动。</p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both;
