Abstract:
A coating system for supplying a coating medium to sheet material during sheet transfer comprising a coating medium applicator system including a form cylinder (2) for applying coating medium to sheet material and a metering system (5) for metering and transferring a predetermined amount of coating medium to said form cylinder (2) or sheet material attached to the form cylinder (2); said metering system including a wiper chamber (4) having a wiper body and at least one wiper blade for containing a quantity of coating material, a screen roller (3) in contacting interposed relation between said wiper chamber (4) and said form cylinder (2) for receiving a metered quantity of coating medium from said wiper chamber (4) and transferring said coating medium directly to said form cylinder (2) or sheet material attached to the form cylinder (2), a sensing device for detecting the temperature of said coating medium; at least one of said wiper chamber (4) and screen roller (3) which contact the coating medium during transport to the sheet material having an associated heat exchanger (A; B) such that the temperature of the coating medium can be influenced during metering or transport immediately prior to application onto the sheet material.
