IBIS Smart-binder options - Buckle folder F-100
The F-100 folder is used to pre-fold sheets before they enter
the Smart-binder infeed. it may be used either to produce small
format books, increase Smart-binder page throughput, or reduce input
For example: to produce A5 (Digest 5.5 x 8.5) books, print oversize A3 sheets (or oversize 11 x 17). These sheets must enter the F100 short-edge leading. The folder then folds the sheet in half to give an oversize A4 (or oversize 8.5 x 11) section with the folded edge leading. These folded sections then enter the Smart-binder, and are processed normally thereafter into finished A5 books.
To produce A4 (or Letter - 8 ½ x 11) books, print oversize A2 sheets (or oversize 17 x 22). These sheets must enter the F100 short-edge leading. The folder then folds the sheet in half to give an oversize A3 (or oversize 11 x 17) section with the folded-edge leading. These folded sections then enter the Smart-binder, and are processed normally thereafter into finished A4 books.
Since sheets are folded into sections before entering the Smart-binder, and books can only be made from whole sections, it is only possible to make books with pages in multiples of 8-pages when using the F100 folder.
Folded sections are more bulky than flat sheets, so this technique may also reduce the maximum number of pages in the book.
The folding process may be deactivated when it is required to pass 4-page sheets through the F-100 without folding.
The F-100 folder may be fitted with optional anti-static bars to reduce the static charge on the sheets delivered to the Smart-binder.
When using ISG gluing together with pre-folded sheets, then a second cold-gluing nozzle must also be installed in the folder (to place a line of glue inside the folded sheet). See option FGS-100.
The F-100 enables the max web speed to be increased to about 180 200 meters/min or, if running off-line, the maximum page throughput to be increased. The F-100 also allows the minimum paper weight to be reduced to approximately 40 gsm (at reduced web speeds).
