Overview
ISO 2012:1976 specifies the maximum usable width of the warp for a given cylinder used in cone sectional warping machines. Published as the first edition in August 1976, this International Standard replaces ISO Recommendation R 2012‑1971 and gives a uniform way to designate cylinder widths for sectional warping equipment. It is intended for use where a definite cylinder of a cone sectional warping machine is defined and documented.
Key topics
- Scope: Defines the maximum usable width of the chain (warp) on a particular cylinder of a cone sectional warping machine.
- Designation: Cylinders are designated by the maximum usable warp width followed by the reference to this standard.
- Example: Cylinder of sectional warping machine, 2600, ISO 2012.
- Standardized widths (millimetres): The standard lists accepted maximum usable-width values. Values appearing in parentheses are legacy sizes that should be avoided where possible and are retained only to account for cylinders already in service. Standard values include:
- (1400), 1800, (2000), 2200, (2400), 2600, (2800), 3000, 3400, 3800, 4200
- Notes on legacy sizes: Parenthesized values are included for compatibility with existing equipment but are not recommended for new designs.
Applications
ISO 2012 is practical for professionals who need a clear, repeatable definition of warping cylinder widths, including:
- Textile machinery manufacturers specifying or labeling cone sectional warping machine cylinders.
- Plant designers and production engineers planning loom and warping-room layouts and ensuring component compatibility.
- Procurement and maintenance teams creating purchase specifications, spare-parts lists, and retrofit/upgrade plans.
- Standards and compliance personnel documenting machine characteristics in technical data sheets and ensuring consistency across equipment from different vendors.
Using ISO 2012 helps ensure consistency in machine specifications, simplifies communication between manufacturers and users, and supports interoperability and replacement of cylinders in cone sectional warping machines.
