1 Scope

GB/T 30420.1-2024 is the general terminology part of the Chinese sewing machinery vocabulary. China makes the overwhelming majority of the world's industrial sewing machines, and the sector's vocabulary has grown from three directions at once, the traditional trade terms, the Japanese and German machine builders whose designs were copied and adapted, and the electronics and automation that have transformed the machines in the last decade; the result is that the same component or function is called several things. The standard defines the general terms of the field: the categories and types of sewing machine, the stitch and seam types, the principal mechanisms, needle bar, feed, looper, hook, thread take-up and tension, the drive and control including the servo motors and the programmable functions, the accessories and attachments, the performance and rating terms, and the terms for the operations performed. It took effect on 1 October 2024.

This document defines the general terminology for sewing machines. This document is applicable to scientific research, design, manufacturing, writing of relevant technical documents and technical exchanges in the sewing machinery industry.
