The technical differences between this document and ISO 8116-5:2008 and their reasons are as follows.

The scope of application of this document (see Chapter 1) has been expanded to suit my country's technical conditions. -the normative reference GB/T 1800.2 replaced ISO 286-2 (see Table 1), and the normative reference GB/T 9239.1 replaced ISO 1940-1 (see Chapter 8), replaced ISO 8116-8 (see Chapters 6, 7 and 8) with the normative reference GB/T 18737.8.

7) to adapt to my country's technical conditions.

For the mechanical strength quality grade of segmented warping beams, the normative reference GB/T 18737.4 replaces ISO 8116-4 (see 5 and 11) to adapt to my country's technical conditions.

The diameters of the side plates were increased to d1 = 535 mm, 660 mm, 812 mm, 876 mm, 1 016 mm, 1 066 mm, and the corresponding the code should be changed; the side plate diameter d1=532 mm, 1 000 mm was deleted; the side plate spacing l1=316 mm, 470 mm, 976 mm; added total length l2 = 540 mm, 1 066 mm; deleted total length l2 = 1 065 mm, 1 270 mm, 1 325 mm, 1 065 mm; added roll diameter d2 =.200 mm, 235 mm, 260 mm, 300 mm; deleted roll diameter d2=196 mm, 298 mm, 360 mm; change the keyway width b=19.6 mm to b=20 mm; change h=165.3 mm to it was changed to h=160.2 mm (see Table 1) to adapt to my country's technical conditions.

The tolerance of the end face circular runout of the side plate has been changed (see Table 2) to adapt to the technical conditions of my country.

The calculation formula of the radial total runout tolerance Tr of the drum (see Chapter 7) has been changed to adapt to my country's technical conditions.

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. The purpose is to describe the main dimensions, mechanical strength and Requirements are put forward for the maximum geometric tolerances of the main elements.

Part 6: Warp beams for ribbon looms and crochet machines. The purpose is to provide basic terms, main dimensions and and requirements for geometric tolerances.

Part 7: Shafts for dyeing sliver, roving and yarn. The purpose is to describe the types of porous shafts for dyeing sliver, roving and yarn.

Requirements are put forward for the format, terminology and marking, and main dimensions of the transmission structure.

Part 8: Definition and measurement of runout tolerances. The purpose is to determine the geometric and positional tolerances (edge and Requirements are put forward for the disk end face circular runout and the total runout of the shaft tube and the measurement method.

Part 9: Shafts for fabric dyeing. The purpose is to provide the types, terms, main dimensions and markings of shafts for fabric dyeing.
