IBIS Smart-binder options - Spine clamp kit B0000586
The Spine Clamp Kit B0000586 reduces book corner tearing when making very thick booklets. All saddle-stitcher side-knives normally result in some tearing of the corner of the book spine. This results from the fact that the V shaped spine is not supported well by upper clamps.
The clamp kit modification ensures that the V spine is better clamped
to reduce spine corner tearing by the side knives. The standard modification
kit is designed to suit A4 or USA 8 ½ x 11" finished book
sizes only. For other sizes refer to IBIS.
