Overview
ISO 93-1:2006 - Textile machinery and accessories - Cylindrical sliver cans - Part 1: Main dimensions specifies the principal dimensional requirements for cylindrical sliver cans used throughout the textile industry. The standard defines symbols, dimensional relationships, tolerances and incremental sizing rules for both sliver cans without castors and sliver cans with castors, and provides a clear designation format for ordering and procurement.
Key topics and technical requirements
- Scope: Main dimensions of cylindrical sliver cans for textile use (Part 1 of ISO 93).
- Symbols and relationships: Defines key symbols such as inside diameter (d), outside diameter at base, diameter of recess, overall height (h) and - in the corrected version - diameter of castor.
- Dimensional rules:
- Prescribed relationships between inside and outside diameters and recess dimensions (e.g., outside diameter = inside diameter + specified allowance).
- Maximum top-rim allowances that increase with can diameter to ensure stability (different allowances for d ≤ 700 mm, ≤ 1 200 mm, and > 1 200 mm).
- Tables and tolerances: Main dimensions and tolerances are given in tabular form for cans with and without castors (specific standard tables specify common d and h values and permissible tolerances).
- Increment rules:
- For cans without castors: inside diameters greater than 700 mm in 100 mm increments; heights greater than 1 200 mm in 100 mm increments.
- For cans with castors: inside diameters greater than 1 000 mm in 200 mm increments; heights greater than 1 200 mm in 100 mm increments.
- Designation for ordering: Standardized format to specify type (with/without castors), reference “ISO 93-1”, number of castors (if any), inside diameter and overall height (e.g., “Can with castors ISO 93-1–3R - 600 × 1 200”).
Applications and who uses it
ISO 93-1:2006 is valuable to:
- Textile machinery manufacturers - to design and produce standardized sliver cans compatible with spinning and preparatory equipment.
- Procurement and supply chain teams - for unambiguous ordering and interchangeability of cans and replacement parts.
- Quality and inspection personnel - to verify conformance to dimensional tolerances.
- Machine designers and equipment integrators - to ensure stability, handling and compatibility (castor selection, floor interfaces).
- Standards bodies and testing labs - for reference and harmonization.
Practical uses include manufacturing specifications, parts interchangeability, warehouse stocking plans, and ensuring ergonomic and stable handling in spinning preparatory processes.
Related standards
- ISO 93-2 (Part 2): Spring bottoms - complements Part 1 by specifying spring-bottom designs and requirements for sliver cans.
- Other textile machinery standards (ISO/TC 72) may be relevant when integrating sliver cans into complete systems.
