| 摘要 |
<p>The present invention relates to a system and method suitable for automatic cleaning of a coating or extrusion head (410) of a coating apparatus. The invention includes a scrubbing station (103) wherein a combination of physical contact (603) and strong solvent solution (503) combine to remove coating fluid from the exterior of an extrusion head (410). A second cleaning station (102), preferably a rinsing station then further cleans the head of coating fluid and removes solvent used at a first cleaning station (103). The solvent used at the rinsing station (102) is preferably self-drying thereby obviating the need for any further cleaning action. The invention also provides for the ability to prime (101) the coating bead at the extrusion head.</p> |
