Introduction

GB/T 18737 "Warp beams of textile machinery and accessories" adopts ISO 8116 standard and is intended to consist of 9 parts. Part 1.Vocabulary. The purpose is to give requirements for the basic vocabulary and type classification of warp beams. Part 2.Warping beams. The purpose is to determine the main dimensions, mechanical strength, shape and position tolerances of warping beams, as well as warping beams with shaft extensions. And put forward requirements for the transmission structure and marking of the warping beam without shaft extension. Part 3.Weaving beams. The purpose is to describe the types and main dimensions, mechanical strength, thread profile, and runout of the weaving beams. The requirements include shaft core radial total runout tolerance, other specifications and markings. Part 4.Quality grades for warping beams, warping beams and section warping beams. The purpose is to describe the principles and practical methods of grading warping beams. The law makes demands. Part 5.Segmented warp beams for warp knitting machines.
