Advantages

These binding spines provide a quick and consistent method to finish documents, enabling easy page turning and a professional appearance without permanent alterations to the pages.

How to use

Punch holes along the binding edge of the assembled A4 pages using a comb binding machine set for the correct pitch, then place a 12 mm plastic spine onto the machine’s opener or align it manually with the punched holes. Open the spine slightly, insert the document pages onto the comb teeth, and then release or close the spine so the teeth engage all holes evenly. Check that the pages turn freely and that the spine is fully seated along the entire binding edge.

Usage recommendations

For best results, verify the sheet count before binding to avoid overstretching the spine. Use spines of matching diameter when creating sets of similar thickness, and store unused spines flat in a cool, dry place to prevent deformation.
