TS 7691 ISO 1505

TS 7691 ISO 1505 is a textile machinery standard that defines the widths used for dyeing and finishing machines and sets out the range of nominal widths. Its main purpose is to make the critical machine width explicit, especially when equipment is being specified or ordered, so that essential dimensions are not left open to interpretation.

Critical width as a purchasing and specification term

In dyeing and finishing lines, width is not just a physical dimension of the machine; it is a key parameter linked to fabric passage, process arrangement, and the usable working zone. The same word can mean different things across machine designs, which is why terminology matters. In general technical practice, standardized width definitions help reduce misunderstandings between buyers, engineers, and manufacturers when comparing machines or preparing technical documents.

Why nominal width ranges matter

Nominal widths provide a common reference point for describing machine size in a consistent way. For textile processing equipment, that consistency supports compatibility checks, plant layout decisions, and clearer supplier communication. This standard’s value lies in organizing that vocabulary around dyeing and finishing machinery, so the width information used in orders and specifications is understood in the same way across the supply chain.

• Defines width terms for dyeing and finishing machines.
• Covers the range of nominal widths.
• Aims to remove ambiguity in orders.
• Helps align the understanding of critical width measurements.
