Eighty Sheets, Folded Right Back Fellowes publishes the white 11mm wire binding comb as suitable for binding 51-80 sheets on 34 loop wire binding machines, with a pack size of 100. At 11mm the published capacity is 51-80 sheets. Training notes, tender responses and monthly reports of that length sit in the band. The loops carry the block while the pages turn around them, which is what a set read cover to cover does all day. White wire reads as part of the page edge, which suits a set going out behind a clear front cover. A wire is closed by the machine and stays closed: the set is bound once rather than opened again for a page swap. At 80 sheets the pages fold right back around the loops. A white wire keeps the spine quiet against pale covers. Fellowes gives the pack as 100. The rest of the range is listed under wire binding combs. The machines that punch and close them are at wire binding machines, a spine that reopens instead is at plastic binding combs, and covers and pouches are in binding and laminating.
