How to use

Place the assembled documents on the comb binding machine and use the machine to punch or align holes if necessary.

Ensure that page edges are flush and that the comb is centered to allow smooth opening and closing of the bound document.

Usage recommendations

For best results, use with standard A4 paper and a comb binding machine rated for 19 mm spines. When binding large or heavy documents, check that the sheet count does not exceed the stated capacity and distribute pages evenly to avoid strain on the comb. Store spines flat in a dry environment to preserve shape.
