Overview
ISO 93-2:2006 - Textile machinery and accessories - Cylindrical sliver cans - Part 2: Spring bottoms defines the principal features of spring bottoms (with and without pre-tension) used in cylindrical sliver cans specified by ISO 93-1. The standard describes dimensional, symbolic and functional requirements for spring plates and springs used at the base of sliver cans in the textile industry, including versions for cans with or without castors.
Key topics and technical requirements
- Scope: Principal features of spring bottoms for cylindrical sliver cans (types A, B, C, D).
- Types:
- Type A / C - spring bottom without pre-tension (A = without castors, C = with castors).
- Type B / D - spring bottom with pre-tension (B = without castors, D = with castors).
- Dimensional rules: Tables provide principal dimensions (spring plate diameter, depths and can sizes) and rules for increments of larger diameters/heights.
- Critical dimensions: Symbols and parameters are defined (e.g., inside diameter of sliver can, outside diameter of spring plate, overall height, depth of spring plate).
- Spring characteristics: Length of unloaded spring, length when constrained, spring force and spring force in top working position. For some types, spring force and tolerances of parallelism must be agreed between producer, machine manufacturer and customer.
- Specified distances: Distance from top rim to spring plate surface is defined - for Types A/C a range (typically 5 mm to 70 mm), for Types B/D a fixed value (20 mm).
- Designation for ordering: Standardized ordering format (example):
Spring bottom ISO 93-2 D 1170 × 34 - 780/85 - indicating type, spring length, spring force, and spring plate dimensions.
Applications and practical value
- Ensures interchangeability and mechanical compatibility between sliver cans and spring bottoms across suppliers and machinery.
- Guides manufacturers in designing and producing spring plates and spring assemblies tailored to specific can sizes and machine requirements.
- Helps procurement and machine builders specify correct spring bottoms (with required pre-tension, force, plate diameter and depth) to maintain consistent sliver handling and storage.
- Useful in quality control and maintenance for replacement parts in spinning preparatory, spinning, twisting and winding lines.
Who should use this standard
- Textile machinery manufacturers and designers
- Spring-bottom and sliver-can producers
- Machine builders, factory maintenance teams and procurement specialists
- Standards engineers and compliance officers in textile industry

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 93-2 was prepared by Technical Committee ISO/TC 72, Textile machinery and accessories,
Subcommittee SC 1, Spinning preparatory, spinning, twisting and winding machinery and accessories.
This third edition cancels and replaces the second edition (ISO 93-2:1999), which has been technically
revised.
