Spiral binding Nenurodyta 1014/534614 12 mm black

Spiral binding coil by Nenurodyta, model 1014/534614, 12 mm diameter in black is designed for manual or machine bookbinding to bind documents, reports, notebooks and presentations. The 12 mm spiral provides a secure hold while allowing flexible page turning and flat opening. Compatible with standard punching patterns, this black coil is intended for everyday use in offices, schools and print-shops where medium-thickness documents need a professional finish.

Advantages

The 12 mm black spiral offers reliable retention and smooth operation when turning pages, reducing wear on perforated edges. Its consistent diameter ensures uniform binding and a neat appearance for bound documents. Suitable for both manual insertion and automatic coil inserters, the coil resists deformation during handling and transport, maintaining document integrity. The neutral black colour integrates with a wide range of cover designs and paper types.

Suitable for

• Binding reports and presentations
• Creating notebooks and journals
• School assignments and student projects
• Small to medium print-shop binding jobs
• Office documents requiring a durable, flexible finish

Key specifications

• Spiral diameter: 12 mm
• Color: black
• Material: flexible binding coil material suitable for standard document binding (plastic/polymer)
• Compatibility: for use with manual coil insertion or automatic coil inserters and standard punched documents
• Suitable document thickness: medium thickness documents (approximate capacity depends on paper weight and punch pattern)

How to use

Prepare documents by punching holes with a coil-compatible punch aligned to the binding edge. Thread the spiral coil through the punched holes manually or use an automatic coil inserter, ensuring the coil passes through each hole evenly. Once the coil is fully inserted, crimp or close the coil ends with a pair of crimping pliers or an appropriate end stop to prevent uncoiling. Check the document for even page movement and trim excess coil if necessary to match document length.

Usage recommendations

For best results, use a punch that matches the coil pitch and ensure pages are stacked evenly before insertion. Avoid excessive force when crimping to prevent deformation. Store coils flat in a dry environment to maintain shape and ease of handling.
