加弹机假捻器用同步齿形带的制造

The Manufacture of Cynchronous Belt for False Twist Device of Texturing Machine

FK6—900、FTF—800、SDS—600等牵伸加弹机上的假捻器用的同步齿形带有MXL型和HTD型两种。带子的主体材料有聚氨酯弹性体和氯丁橡胶两种。成型方法有嵌齿法,予成型法和流通法三种。本文简要叙述三种方法成型的优缺点以及用流通法成型的,以氯丁橡胶为主体材料,玻璃纤维线绳为骨架层,齿面复有尼龙织物的MXL型同步齿形带的制造方法。

There are two types of cynchhonous belts in China for false twist devices for texturing machines of FK6—900, FTF—800, SDS—600 Models, they are MXL and HTD Belts. The main material used is polyurethane elastomer and chloroprene rubber. Three methods are adopted in belt formation: teeth insertion, preconstruction and flowing. This paper introduces briefly the advantages and disadvantages of these methods and the manufacturing process of MXL Type cynchronous belt with flowing method: chloroprene rubber is used as main material, glass fibre cord as the tensile member and the teeth surface covered with nylon fabric.
