Flexible paper web printing machine - has silk screen printing cylinders containing magnetisable roller wipers with magnets below web

摘要

The material web is withdrawn from a supply coil and travels in a flat state in the region of the printing rollers so that the web tension alone does not lead to contact between the pressure base and the web. When the magnetic system of the ink application unit is activated through the magnetic roller wipers, the printing cylinder is pulled down towards the magnetic pressure base - the rollers to effect contact between web and base. If the original speed of the web is greater than that of the rollers then the web section is braked to the speed of the web section eld by the rollers.
