Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies) The work of preparing International Standards is normally carried out through ISO technical committees Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2

The main task of technical committees is to prepare International Standards Draft International Standards adopted by the technical committees are circulated to the member bodies for voting Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights ISO shall not be held responsible for identifying any or all such patent rights

ISO 368 was prepared by Technical Committee ISO/TC 72, Textile machinery and accessories, Subcommittee SC 1, Spinning preparatory, spinning, twisting and winding machinery and accessories

This fourth edition cancels and replaces the third edition (ISO 368:1991), which has been technically revised

INTERNATIONAL STANDARD ISO 368:2006(E)

Spinning preparatory, spinning and doubling (twisting)

machinery — Tubes for ring-spinning, doubling and twisting spindles, taper 1:38 and 1:64

1 Scope

This International Standard specifies the dimensions (length and inner diameter) and permissible total run-out

of tubes with taper 1:38 and 1:64 for ring-spinning, doubling and twisting spindles used in the textile industry

It also specifies the dimensions and tolerances of the gauges for checking the tubes

2 Normative references

The following referenced documents are indispensable for the application of this document For dated references, only the edition cited applies For undated references, the latest edition of the referenced document (including any amendments) applies

ISO 286-2:1988, ISO system of limits and fits — Part 2: Tables of standard tolerance grades and limit deviations for holes and shafts

3 Types, dimensions and tolerances

3.1 Tubes

3.1.1 Tube types

Plain top tubes as shown in Figure 1 a) shall be designated as type A tubes Rolled-in top tubes as shown in Figure 1 b) shall be designated as type B tubes

3.1.2 Dimensions

Tube sizes shall be chosen from the dimensions specified in Table 1

3.1.3 Total run-out tolerance

The permissible total run-out tolerance, Tr, shall be in accordance with the values specified in Table 1 The total run-out shall be measured in accordance with Figure 2

3.2 Gauges

Gauges shall conform to the dimensions and tolerances specified in Table 2

4.2 Gauges

See Figure 3 and Table 2

For checking the internal diameter d1 at the base of the tube by means of the corresponding marks on the gauge, the short part of the gauge shall be used The marks ± b/2 at the long part of the gauge shall be used

for checking the internal diameter d2 and/or d3 at the top of the tube
