IBIS Smart-binder options - Trimmer center-knife assembly CKN-100, CKN-101 or CKN-102

The optional Smart-binder trimmer center-knife system may be used to produce book sizes which are less than 160mm (6 1/4") spine length (e.g: A5 landscape or 8 ½ x 5 ½" oblong). Each sheet is printed with 8 pages instead of the normal 4 pages. These sheets are individually folded and then either stitched or glued together in the normal way. The center-knife then splits the resulting book into two smaller sized books, which are delivered in two parallel streams.

Center-knives are available in widths of 6.35mm (1/4") (CKN-100) and 9.52mm (3/8") (CKN-101). These trim 6.35mm (1/4") or 9.52mm (3/8") out of the middle of the book. Book thickness is limited to 3mm (1/8") for the 6.35mm (1/4"h) knife and 4.5mm (3/16") for the 9.525mm (3/8") knife.

Option CKN-102 can separate the two books without any trim out. Thicker books may be produced if using the CKN-102 single knife center-split instead of a double-edged trim-out knife.
