Overview
ISO 3914-3:1994 - Textile machinery and accessories - Cylindrical tubes - Part 3: Dimensions, tolerances and designation of tubes for tape yarns - defines the dimensional and designation rules for cylindrical winding tubes used specifically with tape yarns. This second edition (1994) cancels and replaces ISO 3914-3:1984 and provides standardized guidance on main dimensions, tolerances and inspection methods for tube inner diameter and length. The standard supports interchangeability and quality control across textile winding and preparatory machinery.
Key topics and technical requirements
- Scope: Specifies main dimensions, tolerances and designation format for cylindrical tubes intended for tape yarns; gives directives for tube characteristics and measurement control.
- Manufacturer-declared characteristics (to be specified):
- Material: paper or plastic
- Nature of yarn to be wound
- Wall thickness (appropriate to yarn type)
- Treatment: impregnated or non-impregnated
- Groove for transfer tail (if required)
- Dimensional control:
- Inner diameter: checked with a GO / NOT GO gauge (GO/NOT GO type)
- Tube length: verified with a suitable length gauge (for example, a slide-gauge)
- Designation format: The standard prescribes a clear designation string including the standard reference and the tube size. Example:
- Cylindrical tube ISO 3914-3 - 90 x 230 (inner diameter 90 mm, length 230 mm)
- Normative reference: ISO 3914-1 (Recommended main dimensions) is referenced for principal dimensions.
Applications and practical value
- Ensures compatible tube dimensions across suppliers and winding machinery for tape yarns, reducing machine setup time and package handling errors.
- Provides quality control protocols for production inspection and incoming goods acceptance (use of GO/NOT GO gauges and length checks).
- Useful for procurement specifications and technical purchase documents to guarantee interchangeability and conformity.
- Supports machine designers and integrators in specifying parts that match standardized dimensions for winding, transfer and downstream processing.
- Tube manufacturers (paper and plastic tube producers)
- Textile machinery designers and OEMs (winding/preparatory equipment)
- Quality control and inspection teams in textile mills and converters
- Procurement/specification engineers who require standardized tube designation and tolerances
