ABSTRACT:
A filter apparatus and coating method particularly adapted for thixotropic coating solutions and which yet permits the dead space within the housing of the filter apparatus for the secondary region to be reduced under a broad range of conditions at all times. The improved filter apparatus has a filter provided within a housing in such a way that it divides the interior of the housing into a primary region into which a coating to be filtered is supplied and a secondary region which receives the coating solution after it is filtered. The apparatus filters the coating solution just before it is coated on a flexible base. The apparatus is characterized in that the housing for the secondary region is designed in such a way that an index for measurement of the dead space within the housing satisfies the relation T/.tau.> 0.95, where .tau. is an experimentally determined dimensionless number for the indicial response time of the housing and T is a dimensionless number of theoretical time.
