Lay flat binding with its panorama images finds increasingly new applications outside the traditional photo books. Advertising agencies are discovering the added possibilities this attractive binding method offers. Company profiles, descriptions of building projects and interior design brochures are increasingly produced in lay flat. With this trend PBT received recently additional orders for mitabook casing-in lines to produce this type of products. The mitabook, does not require a wing and therefore there is no need for a book block splitter to find the center of the book. This book splitter adds to the danger of slicing the glued double page and marking the printed image. All these recently sold machines were equipped with the additional mitaform joint forming attachment.
