TS 7127

TS 7127 is a standard that addresses the principal terms and key dimensions of flanged bobbins used in textile machinery for doubling and twisting. In textile production, these bobbins are important components for winding, guiding, and handling yarn in a controlled way; bringing terminology and dimensions into a common framework helps maintain consistency across machines and accessories.

Why terms and dimensions are defined together

The standard links nomenclature with the functional geometry of the bobbin. From a general technical perspective, flanged bobbins differ from plain spools because their side flanges help confine the yarn package and influence winding stability, package form, and process suitability. In doubling and twisting operations, the bobbin geometry can affect yarn handling and the stability of movement within the machine.

Technical scope of this document

• Covers the principal terms used for bobbins in doubling and twisting machinery.
• Gives the important dimensions of flanged bobbins.
• Supports a common technical language in textile machinery and accessories.
• Identified as equivalent to ISO 6169:1982.

Rather than serving as a design manual, the document functions as a reference for dimensional and terminological alignment. Its main value is helping different suppliers or machine types refer to the same component in the same way and with the same dimensional logic. TS 7127 was withdrawn in 2021.
