A rotary coater device (12) is provided, comprising front and rear frame plates (30) having mounted therebetween: a die bracket assembly (100), a screen assembly (200), a heater hood assembly (300), and an impression roll assembly (400). The die bracket assembly (100) includes (i) a die (500) positionable within a screen (202) and having an opening (550), the die being movable from an operating position wherein the die opening is proximate to an inner surface of the screen to an idle position wherein the die is drawn away from the inner surface; and (ii) a pivotable support arm (102a) fixedly attached at one end to a positioning mechanism (112) and removably attached at an opposite end to the die, the pivotable support arm being pivotable away from the screen when the opposite end is detached from the die to expose the screen for removal from the coater device. The screen assembly (200) supports the cylindrical screen in an operating axial position about a first axis (127), and includes (i) at least one guide wheel (206) engageable with the screen and (ii) a retractable support arm (238) pivotable about an axis (72) from a first position wherein the at least one guide wheel is engaged with the screen in the operating axial position, to a second position wherein the at least one guide wheel is disengaged from the screen. The heater hood assembly (300) assures an evenly heated outer surface of the screen. The impression roll assembly (400) includes an impression roll (402) which provides a backing for a web to be coated by the coater device.
