单针罗拉?/a>的用?

采用滚轮及针送同步送科,爬坡力强,针距变化小,针位极稳定。缝制海棉、薄皮等缝科,平滑平均,不起皱,不变形。采用球型及针状轴承,光滑性能好、磨擦小、噪音低、经久耐用。适用于马靴、运用于马靴、运动鞋、休闲鞋、海棉鞋、婴儿鞋、高级皮革鞋类及箱包缝制?

单针罗拉?/a>缝制粗线的调?

由于罗拉车面线运用的?#粗线,缝纫时缝料底面会呈现一个或多个很硬的线结,相似浮线,但面线已绷得很紧,将面线再收紧同样会有此现象,而且缝制出来的产品会变得弯曲、起皱,达不到工艺请求。经过察看并屡次调整和改换机针、针板等,终于处理了这一问题?

调整单针罗拉车技巧如下:

(1)针与针板的选择

假如机针太粗会使缝料上的针孔过大影响质量,假如机针太细又容易形成断线,多数状况是先断一股,然后再断另外两股。针板要选用容针孔稍大一些的,过线槽局部也要宽一些,大约6.5mm为宜,假如过线槽太窄,能够用合金锉刀将过线槽前端磨宽一些,这样有利于缝线顺利经过?

(2)针杆与旋梭的配合

在针杆上升时可以构成线环,并且梭尖可以顺利地勾到缝线的状况下,针杆的高度应尽量调高一些,针杆越往上调,线迹越容易调整。旋梭的位置应调整到针杆上升至旋梭尖在直针中心位置时,梭尖在针孔上面0.5mm处,以不碰到梭尖为好?

(3)收线天秤的调?

收线天秤的时间要调快一些,在梭尖勾到缝线后,带着缝线刚好走到过线槽时,收线天秤开端往上收紧缝线,在缝线经过线槽时牛角把旋梭架与过线槽之间拨开稍大?#珠光线的间隔,让缝线顺利经过。挑线簧的力度要略微调轻些,在面料不起皱和不弯曲的状况下,底线和面线都应调紧些,这样有利于线迹的稳定?
