NATIONAL FOREWORD

This Indian Standard (Part 2) which is identical with ISO 10787-2 : 1994 ‘Textile machinery andaccessories — Heald frames — Part 2 : Heald-carrying rod fixed directly on the frame stave —Coordinated dimensions’ issued by the International Organization for Standardization (ISO) wasadopted by the Bureau of Indian Standards on the recommendations of the Machinery for Yarn andFabric Manufacture Sectional Committee and approval of the Textile Division Council.

This standard has been prepared in supercession to the earlier Indian Standard IS 10936: 1984/ISO 569:1982 ‘Co-ordinated dimensions of heald frames in relation to the pitch of the harness’. SinceISO 10787 published in three parts cancels and partially replaces ISO 569:1982 on which IS 10936:1984 was based.

This standard consists of three parts under the general titles ‘Textile machinery and accessories —Heald frames’:

Part 1 Heald-carrying rod fixed to the frame stave by rod support — Coordinated dimensions

Part 2 Heald-carrying rod fixed directly on the frame stave — Coordinated dimensions

Part 3 Guides for heald frames

In this standard, the text of ISO Standard has been approved as suitable for publication as an IndianStandard without deviations. Certain conventions are, however, not identical to those used in IndianStandards. Atlention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should beread as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the currentpractice is to use a point (.) as the decimal marker.

CROSS REFERENCE

In this adopted standard reference appears to the following International Standard for which IndianStandard also exists. The corresponding Indian Standard which is to be substituted in its place islisted below along with its degree of equivalence for the edition indicated. However, that InternationalStandard cross-referred in this adopted ISO Standard, which has subsequently been revised, positionin respect of that latest ISO Standard has been given:

For the purpose of deciding whether a particular requirement of this standard is complied with, thefinal value, observed or calculated, expressing the result otit or analysis, shall be rounded off inaccordance with IS 2 : 1960 ‘Rules for rounding off numerical values (revised)’. The number ofsignificant places retained in the rounded off value should be the same as that of the specified valuein this standard.

PART 2 HEALD-CARRYING ROD FIXED DIRECTLY ON THE FRAME STAVE —COORDINATED DIMENSIONS

----

This part of ISO 10787 specifies the coordinated di-mensionsof heald frames on which the heald-carryingrod is fixed directly on the frame stave.

2 Normative reference

The following standard contains provisions which,through reference in this text, constitute provisionsof this part of ISO 10787. At the time of publication,the edition indicated was valid. All standards are sub-ject to revision, and parties to agreements based onthis part of ISO 10787 are encouraged to investigatethe possibility of applying the most recent edition ofthe standard indicated below. Members of IEC andISO maintain registers of currently valid InternationalStandards.

ISO 2768-1:1989, General tolerances — Part 7: Tol-erances for linear and angular dimensions without in-dividual tolerance indications.

3 Heald frame

Figures 1 and 2 and table 1 define and specify the di-mensions of heald frames on which the heald-car~ingrod is fixed directly on the frame stave.

4 Heald frame connections

Figures 3 and 4 show heald frame connections at theupper and lower frame staves, respectively, while ta-ble 2 specifies their dimensions,

1) PitchI of the harness:distancebetween the midpoints of two adjacent heald frames of a harness in a weaving machine. Normally thepitch of the harness is aqual to the pitch of the shedding motion, i.e. the distance between the midpoints of the needles in the dobby orother drwing mechanism of the heald frames. The dimension shown in parentheses should be avoided for new constructions.

2) The distances between end loops of healds are derived from inch dimensions.

3) m2=~+v

The value of v depends on the kind of heald frame connection and is therefore fixed by the machine manufacturer.
