Abstract:
An apparatus for applying a coating liquid to a printing substrate from a first paper path, comprising:a. a rotatable first roll; b. a rotatable second roll positioned adjacent to the first roll and defining with the first roll a first nip through which the printing substrate passes; c. a metering device for applying a layer of coating liquid onto the second roll, which in turn transfers the coating liquid to the printing substrate; and d. a controller communicating with at least the second roll, the controller performing the steps of: (i). Determining whether the idle time of the second roll is longer than a predetermined threshold; (ii). Setting a pre-spin flag if the idle time of the second roll is longer than a predetermined threshold; and (iii). Directing the second roll to perform a pre-spin upon the presence of the pre-spin flag.
