Servo takeover for flexo printing
machine control
Servo drive and control technology has made mechanical line shafts, gearwheels, gearboxes and cams redundant for designers of flexo printing machines.
Servo drive and control technology has made mechanical line shafts, gearwheels, gearboxes and cams redundant for designers of flexo printing machines The high precision synchronisation which is possible with controls such as Rexroth Indramat's SYNAX200, means that all machine units are operated by single drives

Aberdeen Control opts for Rexroth software
When Aberdeen Control was asked to create a new design for a control cabinet to remotely control a diesel engine driven pump on an oil rig, they proposed using a Bosch Rexroth PLC-based control.
This includes linear motion sequences such as the ink-deck pre-positioning of the anilox and printing cylinder as well as gravure, gluing and processing units.
It also covers the printing cylinders, impression cylinders, screen rollers, inking and coating units, paper in-feeds and outfeeder.
The first drive and control solution for seven colour in-line flexo printing was produced by Rexroth Indramat in 1996.
Benefits accruing from this include infinitely variable format length because repeat length grading, previously given by gear pitch, is eliminated.
The removal of format gears and the gearmesh procedure considerably reduces setting up time.
Most leading manufacturers of flexo printing machines have now developed new machine designs with servo drive technology.
For example Fischer and Kreckes' new machine for flexible packaging features sealed chamber doctor blade assemblies, designed for easy handling, ceramic anilox rolls for precise and constant ink transfer and servo AC motors in all relevant drive positions.
