8、 : 1995 Textile machinery and accessories Part 2: Dimensions, tolerances and designation of cones with half angle 3“ 30 Cones for cross winding Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of pr
9、eparing International Standards is normally carried out through IS0 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, i
10、n liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publ
11、ication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 8489-2 was prepared by Technical Committee ISO/TC 72, Textile machinery and allied machinery and accessories. Sub- committee SC 2, Winding and preparatory machinery
12、 for fabric manufac- ture. This first edition of IS0 8489-2 cancels and replaces IS0 112:1983, which has been technically revised. IS0 8489 consists of the following parts, under the general title Textile machinery and accessories - Cones for cross wmding: - Part I: Recommended main dimensions - Par

Furthermore, directives are given for the characteri
15、stics of cones and for the control of the diameters and lengths of the cone. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 8489. At the time of publication, the editions indicated were valid. All sta
16、ndards are subject to revision, and parties to agreements based on this part of IS0 8489 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

They do not influence the practical us
21、e of the cones during winding and further processes. *) In certain cases, especially for automatic winding, dimensions of this size must be agreed upon between the interested Darties in relation to the wall thickness. *) Main dimensions as recommended in IS0 8489-1. 4 Characteristics The following d
22、etails shall be specified by the manufacturer: a) cone material (paper or plastic); b) surface treatment (paper: untreated, impregnated or lacquered); c) nature of yarn to be wound; d) thickness of cone wall (corresponding to the nature of the yarn to be wound); e) run-out tolerance (if required); f
23、) details of tailing groove and notch for tail (if required); g) number, size and location of perforations (if required). The minimum distance between the ends of the cone and edges of the nearest holes, if any, shall be 16 mm k 0.5 mm. Page 5 IS0 8489-2 : 1995 5 See figure2 a) and b) and table2. Di

Page 6 IS0 8489-2 : 1995 The inner dimensions of the cone are in accordance with this part of IS0 8489 if the edge of the larger end of the cone, after it has been placed gently on the gauge a
26、nd then pressed firmly home by hand, is between the tolerance marks. To check the smaller diameter of an open-ended cone, it shall be placed firstly with the smaller end on the gauge. The edge of the smaller end of the cone must then lie between the tolerance marks on the corresponding end of the ga
27、uge. 6 Control of cone length To check the tolerances of the length of the cone, a suitable gauge for checking lengths, for example a slide-gauge, must be used. The conical gauges shown cannot be used for this purpose. 7 Designation The designation of a cone for cross winding with a half angle of 3”
