羅拉(Roller)是纺织机中比较精密机件之一。制造过程繁多,由於使用者要求较高,因之其中问题很多。现在提出三个问题来讨论: (1)方孔方筍制造所发生之困难。一 羅拉规格 羅拉是精纺机(Ring Spinning Frame)及粗纱机(Fly Frame)中为了达到牵伸(Draft)目的的一种机件。牠是由许多节接成一长根(第一图)。连接的方法有二:——(1)用螺丝接頭(Screw Joint),(2)用方筍接头(Square Joint)。关于这两种接头的优缺点,本期读者通讯将有论及。
Roller is one of the more sophisticated machines in textile machines. There are many manufacturing processes and there are many problems due to the high user requirements. Three questions are now proposed to discuss: (1) The difficulties that occurred in the manufacture of Fang Kongfang bamboo shoots. A roller specification Roller is a machine for drafting purposes in a Ring Spinning Frame and a Fly Frame. It is a long root of many sections (first figure). There are two ways to connect: - (1) Screw Joint, (2) Square Joint. The advantages and disadvantages of these two types of connectors will be discussed in the reader communication in this issue.
