Linear Cutters  
MDS Ltd Linear Traverse Cutters offer repeatable, high accuracy cutting for many extruded sheet and other slow-moving web processes. A multi-axis Servo Drive System locks the linear-guided Cutter Carriage precisely on to web speed whilst a cutting head traverses the feed direction and cuts the web. The Cutters shown are fitted with “Flying Knives” and replace conventional guillotines on poly-board extruding lines – high cut-accuracy removes the need for additional off-line product trimming. MDS Ltd can design these units with a variety of different cutters, as well as offer the same basic control platform for other positioning / following applications.
