ISO 26243:2007

Overview

ISO 26243:2007 - "Cards for staple fibres spinning - Vocabulary and principles of construction" is an international standard that defines the terms, definitions and basic construction principles for carding machines used in cotton and other staple fibres spinning. It standardizes vocabulary for components, width dimensions, sides and work-flow orientation of cards, and outlines construction variants and standard working widths to support consistent design, manufacture, operation and technical communication in the textile industry.

Key Topics

• Scope and purpose: Specifies terms and definitions relevant to carding in the spinning process for staple fibres.
• Core vocabulary: Clear definitions for essential elements such as card, flat card, cylinder (tambour), revolving flat, doffer, stripper roll, feed roll, opening roll, licker-in(s), transfer trunk, feed tray, webspeed, cross belt, and sliver funnel.
• Dimensions and orientation: Standardized width terms - clothing width, cylinder width, working width - and definition of sides (left/right, drive side) referenced to ISO 92.
• Component functions: Descriptions of feeding systems, pre-carding/post-carding zones, cleaning devices (flat strips roll, cleaning roll), and web doffing and sliver formation elements (press rolls, delivery roll).
• Principles of construction: Feeding variants (integrated feeding vs feeding with transfer), card configurations (one licker-in, three licker-ins), delivery systems (cross-belt, webspeed), and standard working widths of 1 000 mm and 1 500 mm.
• Measurement and air balance: Includes devices to measure web thickness and elements such as cylinder cover (bottom) to regulate air balance under the cylinder.

Applications

ISO 26243:2007 is practical for:

• Textile machinery manufacturers - to design and document carding machines with standardized terminology and construction options.
• Spinning mills and operators - for machine selection, safe operation, and process optimization in cotton and staple fibre spinning.
• Procurement and quality teams - to specify equipment requirements and ensure interoperability.
• Technical writers, trainers and educators - to create manuals, teaching materials and training programs using approved definitions (reproduction of terms permitted for educational/implementation use).
• Standards committees and regulators - for consistent referencing in regulations and technical specifications.

Related Standards (if applicable)

• ISO 92 - defines machine sides (left or right) and is cited as a normative reference in ISO 26243:2007.
