TS 1187

TS 1187 is a textile standard that brings together the terminology for serrated bars used in mechanical warp stop motions and the dimensions of the assembled cross-section. From its title and scope, the standard is concerned with how the toothed elements in mechanical warp-stop devices are named and how their fitted geometry is described, which matters for understanding yarn-control arrangements in weaving machinery.

Core concepts in mechanical warp stop motions

Warp stop motions are reliability-oriented mechanisms on weaving machines that react when a warp yarn breaks, typically by stopping the relevant machine action or generating a control signal. The serrated bars covered by this standard can be understood as components that help track warp-yarn position and create a regular geometric pattern within the device. Standardised terminology helps designers, operators and suppliers refer to the same parts consistently across the textile machinery field.

Why terms and dimensions are treated together

The assembled cross-section dimensions refer to the component in its installed state rather than as a loose part. This is useful when assessing fit, placement and mechanical interaction inside the warp stop motion assembly. The standard provides a common technical language for these names and dimensions, but this page does not imply specific mandatory limits, tolerances or test procedures beyond what is indicated by the supplied title and scope. In practice, such terminology standards support clearer drawings, specifications and communication in textile machinery engineering.

This document was published as equivalent to ISO/R 1865 and has since been withdrawn. It is therefore best understood as a historical reference for terminology and dimensional description rather than a current mandatory basis for use or certification.
