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. circulated to the member bodies for voting.

This International Standard applies only to drop wires suited for Uster and Reed Chatwood1) automatic drawing-in systems. These drop wires are always closed with U-shaped thread eye and are distinguished as follows: a) for mechanical and electromechanical warp stop motions M1 (for the Uster drawing-in system) M2 (for the Reed Chatwood drawing-in system) M3 (for the Uster and Reed Chatwood drawing-in systems) b)for electrical warp stop motions E1 (for the Uster drawing-in system) E2 (for the Reed Chatwood drawing-in system) E3 (for the Uster and Reed Chatwood drawing-in systems) 2 Dimensions 2.1 The dimensions of drop wire types M1, M2 and M3 for mechanical and electromechanical warp stop motions and suitable for the automatic drawing-in process are given in figure 1 and table 1. 2.2 The dimensions of drop wire types E1, E2 and E3 for electrical warp stop motions and suitable for the automatic drawing-in process are given in figure 2 and table 1. 1) This information is given for the convenience of users of this International Standard and does not constitute an endorsement by isO of the systems named. Equivalent systems may be used if they can be shown to lead to the same results. tional Organization for Standardization 1 Copyright Intern Not for Resal
