A good example: a glued-off and folded hardcover book block with a perfectly rectangular spine shape.
Specific Solutions with the Vareo Perfect Binder
In addition to preparing the book blocks before binding, there are a number of options with the Vareo
that make the processing of thread-sewn book blocks extremely easy. For example, when switching from pure softcover production with milled spines to the production of thread-sewn book blocks, the new hangout setting option can be used to automatically adjust the distance between the clamps and the processing stations. For softcover production with milled spines, the hangout should be as small as possible in order to guide the spine during the milling and pressing process and ensure a good rectangular shape. By contrast, for the liner production of thread-sewn book blocks, a large hangout makes it easier to guide the liner tightly and properly – both along the spine and the pages, depending on the lateral liner overlap.
For the softcover production of thread-sewn products with a cover (i.e. without spine preparation), a medium hangout setting can be selected in order to ensure sufficient space for optimal gluing and cover pressing based on the specific spine shape. Depending on the desired product type, the time management of lateral pressing and spine pressing in the rubdown station is also always automatically adjusted.
Thanks to the inclusion of a crash station, there is no longer any barrier to the unique application of a liner stripe with the Vareo. The thickness of each book can be adjusted fully automatically and the overlap of the lateral liner stripe may be symmetrical or asymmetrical and adjusted on each page.
In addition, the Vareo also includes optional interchangeable spare parts for the side-gluing discs and the side printing plates with different contours and heights. The operator can use these to respond ideally to each individual product and thus ensure a high level of binding quality.
And One Final Point
The options available in the Vareo itself as well as the interchangeable parts not only enable the optimal binding of folded and/or thread-sewn products. They also make it possible to produce high-quality special brochures – like Swiss Brochure and Otabind (with special scoring tools). This is a feature that is unique to this class of machine!
