Abstract:
An apparatus for metering coating on a moving substrate comprising:a backing roll which engages a substrate to be coated, the backing roll and the substrate extending in a cross machine direction;a short dwell coater head housing positioned beneath the substrate and extending in the cross machine direction;an upstream baffle plate, mounted on the short dwell coater head housing which extends from the housing toward the backing roll;a means for premetering coating on the substrate, which is mounted on the short dwell coater head housing and which extends toward the backing roll from the housing, wherein the mean for premetering is spaced downstream from the baffle plate and a coating pond is formed between the means for premetering and the baffle plate, the means for premetering being supported for motion toward the substrate on an inflatable pneumatic tube;a coating supply passageway between the upstream baffle plate and the means for premetering coating, for supplying coating to the coating pond;a series of means for profiling in the cross machine direction mounted on the short dwell coater head housing and disposed beneath the means for premetering and the pneumatic tube, the means for profiling being spaced from one another in the cross machine direction;a controller operatively connected to each of the series of means for profiling; anda final metering blade mounted on the short dwell coater head housing and positioned downstream of the premetering means and extending from the short dwell coater head housing toward the backing roll, the final metering blade engaging the substrate.
