From simple advertising messages to sophisticated coupon booklets or maps in guide books, with the new retrofittable TWE¦ENMC option smaller folded signatures can also be stitched in a book block. “Such shortened signatures, called tweens, provide great added value”, explains Jurgen Noll, Managing Director Marketing und Services of Muller Martini Book Technology GmbH. “They lend themselves for example to high-quality inlays in photo books or art books, or to conveying knowledge in textbooks in an interesting way”. New product ideas also arise from the possibility of stitching in signatures with different fold types, such as a double-parallel fold or a zigzag gatefold.
World Premiere in Thread Sewing
The Ventura MC is the first book sewing machine on the market that is capable of stitching products featuring signatures in different sizes and positions. An additional servo drive in the sewing saddle enables the tweens to differ both in length and width and to be variably positioned in the book block. “Thanks to the motion control drive design, the lug chain adjusts independently to the different sizes and the tweens can be processed entirely automatically”, adds Noll.
Easy to Retrofit
The TWE¦ENMC option was first unveiled at China Print 2013 in Beijing and attracted so much interest among visitors that many spontaneous purchases were made. New machines are already fitted with the new solution, and it is easily retrofittable on machines from the 2/11 series and onwards. For Ventura MC machines with an older year of manufacture, it is necessary to check individually whether an upgrade is possible.
