Andritz Kuesters arc underlining their worldwide reputation as pioneers and experts for deflection-controlled roll systems by presenting a high precision doctor blade at this year's Techtextil. The patented My-croCoat system makes coating or finishing of webs with a precision in the μ range (one thousandth of a millimetre) achievable. Like the well known S-Roll and HyConrnRoll systems by Andritz Kuesters the fixed comma doctor blade MycroCoat has a deflection-control which facilitates an exactly defined precise nip against the optimally bedded counter roll. Continuous measuring of thickness and grammage allows for automatic application control in a closed loop under running production. This way disturbance variables, such as changes in viscosity of the coating substance or rise in nip pressure at increasing speed can be compensated immediately. On request the MycroCoat system can also be provided with a temperature control.
