在纺织工厂里,有时候为了织出结实耐用的织物,需要将几根细纱合并起来,加上撚度制成合股线,再去织造。这种合并细纱的机器,叫做并纱机。过去我国纱织厂使用的并纱机,都是从外国进口来的,这种机器都很陈旧,效率不高,运转速度只能达到每分钟100米左右,满足不了我国工业生产发展的需要。为了改变这种技术落后的状态,天津纺织机械厂便开始试制一种新的并纱机,这种机器设计新颖,结构精密,运转速度达到每分钟350米,所以叫做高速并纱机。现在这种机
In a textile factory, sometimes it is necessary to combine several spun yarns in order to weave a strong and durable fabric, and twist them into plied yarns before weaving. This machine that combines the spun yarns is called a yarn doubling machine. In the past, the yarn doubling machines used by our yarn mills were all imported from foreign countries. Such machines are very old and inefficient. The operating speed can only reach about 100 meters per minute, which can not meet the needs of China’s industrial production development. In order to change the backwardness of this technology, Tianjin Textile Machinery Factory began trial production of a new twisting machine. This machine has a novel design, a precise structure, and a running speed of 350 meters per minute. It is called a high-speed yarn winding machine. Now this machine
