Full title and description

Textile machinery — Mixing bale openers for cotton spinning — Vocabulary and principles of construction. This International Standard defines terms and gives the basic principles of construction for mixing bale openers used in cotton spinning processes.

Abstract

ISO 20727:2004 establishes a vocabulary of terms and the principles of construction applicable to bale openers that perform mixing and opening of cotton bales in preparatory spinning operations, to provide consistent terminology and guidance for manufacturers, users and standards writers.

General information

• Status: Published (confirmed international standard).
• Publication date: 3 November 2004 (ISO edition 1, 2004-11).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 01.040.59; 59.120.10 (textile and spinning machinery classifications).
• Edition / version: Edition 1 (2004).
• Number of pages: 10 pages.

Scope

This standard specifies vocabulary (definitions) and outlines principles of construction for mixing bale openers used in cotton spinning preparatory processes. It is intended to harmonize terminology and construction concepts so that manufacturers, engineers and users have a common reference for design, specification and communication.

Key topics and requirements

• Standardized vocabulary for components and functions of mixing bale openers (definitions of parts and actions).
• Principles of construction covering main design concepts and arrangements relevant to bale opening and mixing equipment.
• Classification of machine functions and typical component relationships to support clear specification and procurement.
• Guidance to promote interchangeability and clearer communication between manufacturers and users (design-level principles rather than detailed dimensional specifications).
• No extensive normative references — focuses on terminology and construction principles for the specific machine class.

Typical use and users

Engineers and designers of textile and spinning preparatory machinery, machine manufacturers, technical writers and standards committees, procurement and maintenance personnel in cotton-spinning mills, and training/education providers in textile engineering who need consistent terminology and design guidance for mixing bale openers.

Related standards

Other ISO and national standards for textile machinery and spinning preparatory equipment are related (for example standards in the ISO/TC 72 family). National adoptions and identical counterparts (examples) include NEN-ISO 20727:2004 and various national translations/adoptions; related machine standards in the spinning-preparatory area (e.g., hopper feeders, other opener types) provide complementary guidance.
