Muller Martini debuted several new innovations at drupa for mid-range perfect binding. The booth featured live demonstrations of the latest addition to our family of perfect binders, the Alegro, which offers faster setup, shorter production times, and higher product quality. The Alegro utilizes the proven design concept of Motion Control (MC) which replaced mechanical drive systems with servo drives, for fast, repeatable, accurate setup and operation. Visitors saw books ranging in size from 4” x 4” to A5, with a very short changeover in between. The binder was complemented by our newest three knife trimmer, the Solit. Based on the proven success of the Orbit trimmer, this mid-range trimmer utilizes many of the same design elements, including our patented SmartPress adaptive pressing system, tool-less changeover in less than three minutes, and separate servo drives for all major areas including the infeed, knife trimming action, and book delivery.
