Abstract
A coating method and an extrusion-type coating head in which turbulence at the junction between two flows of coating materials is prevented to provide multi-layer simultaneous coating over a wide range of coating rates and with a good coating quality. An intermediate block is sandwiched betwen a rear block defining a back edge and a front block defining a doctor edge. Two coating flows pass through slits formed on either side of the intermediate block, joining at the top end of the intermediate block and flowing together into a short slot extending between the end of the intermediate block and the outlet of the head.
