ISO 1505:1993

Overview

ISO 1505:1993 - "Textile machinery - Widths relating to dyeing and finishing machines - Definitions and range of nominal widths" standardizes the principal machine widths used in dyeing and finishing equipment. It defines eight critical widths and prescribes a range of nominal widths so that dimensions can be specified without ambiguity in orders, technical drawings and procurement documents.

This standard is essential for manufacturers, specifiers and plant engineers who require clear, repeatable dimensions for machine elements that contact or house textile fabric during treatment.

Key Topics

• Defined widths: The standard defines the principal widths such as maximum working width (a1), minimum working width (a2), nominal width (b) and others related to frames and beam elements.
• Range of nominal widths: A tabulated range of nominal widths is provided in millimetres (Table 1). Example values include 1000, 2000, 3000, 4000 ... up to 6800 mm; values shown in parentheses should be avoided where possible.
• Machine element dimensions: Definitions cover widths of machine elements in contact with the fabric, internal frame widths and the effective widths of beams or rakes on machines fitted with tension chains.
• Dimensional relationships: The standard includes algebraic relationships linking widths and adjustment dimensions so manufacturers and integrators can calculate interfaces and clearances consistently.
• Informative annex: Annex A is informative and the bibliography references related classification standards (e.g., ISO 1506:1982).

Applications

• Procurement and orders: Use the standard to specify machine widths unambiguously in purchase orders and contracts, reducing misinterpretation between buyers and suppliers.
• Machine interfacing: Apply nominal-width definitions when engineering connections between dyeing and finishing line modules to ensure proper alignment and fabric handling.
• Plant layout and installation: Use the tabulated nominal widths for planning factory layout, access clearances and integration of modular equipment.
• Quality assurance and documentation: Include defined width terms in drawings, test plans and validation records to maintain consistency across suppliers and production sites.

Related Standards

• ISO 1506:1982 - referenced in the bibliography for general classification and nomenclature of dyeing and finishing equipment.

ISO 1505:1993 improves interoperability and reduces ambiguity by standardizing how widths are defined and selected for textile machinery. For engineers and procurement teams, adopting these definitions supports clearer orders, consistent machine interfacing and more efficient plant layouts.
