Overview
ISO/TR 8517:1988 - "Rubber- or plastics-covered rollers - Glossary" is an ISO Technical Report (published 1988) providing a bilingual (English/French) glossary of 135 terms commonly used in the roller-covering industry. Prepared by ISO/TC 45 (Rubber and rubber products) as a type‑3 technical report, it documents the state of the art rather than prescribing mandatory requirements. The report includes alphabetical indices in both languages and cross-references to related ISO vocabularies.
Key Topics
The document defines terminology and conventions relevant to rubber-covered rollers and plastics-covered rollers, including:
- Construction terms: core, shell, cover (covering), journal, capped end, dummy arbors.
- Operating conditions: drive roller, idler roller, nip width, nip length, nip load (expressed, for example, in N/mm), nip pressure (N/mm²).
- Dimensions & geometry: cover face length, concentricity, eccentricity, radial run-out (TIR), cylindricity.
- Crown profiles: crown (camber), inverse crown, taper crown, barrel crown, compound and primary crown concepts and their intended effects on nip pressure distribution.
- Surface & balance: surface characteristics of plain and grooved rollers and terminology linked to balancing.
- Terminology rules: how synonyms are presented, treatment of “roller” and “rubber” within the glossary, and exclusions (e.g., general rubber terms are covered in ISO 1382).
The report references related vocabularies and standards (ISO 472, ISO 1382, ISO 1925, ISO 4287-1, ISO 6123-2) for topics outside its scope.
Applications
ISO/TR 8517 is practical for:
- Roller manufacturers and coverers defining product specifications and drawings.
- Design and maintenance engineers in paper, printing, textile, converting, coating and web-handling industries who need consistent terminology for roller geometry, surface finish and operating parameters.
- Procurement and quality teams writing contracts, inspection criteria or test procedures for covered rollers.
- Technical writers, trainers and standards committees seeking consistent bilingual terminology for documentation and international communication.
Using this glossary helps avoid ambiguity in specifying nip pressure, crown profile, radial run-out and other critical roller attributes that affect process performance, web tension, coating uniformity and equipment life.
