- 特に固形の物質と、溶解された物質とを液状の媒体内に有する少なくとも一種類の被覆懸濁液によって、少なくとも所定の要求された目標量に相当する量で、湿った状態において、一連の円筒状の連続気泡性の物体を被覆するための方法であって、この場合、被覆過程が、付与される湿被覆量の変動幅を物体ごとに有している形式のものにおいて、当該方法が、以下の方法ステップ:すなわち、
a)被覆懸濁液による物体の被覆によって出発被覆を実施し、
b)物体に付与された出発被覆の実際量を検出し、
c)まだ湿分を帯びている被覆懸濁液の除去または付加的な被覆懸濁液の付与によって実際量を補正し、これによって、最終的な被覆の被覆量が、目標量を上回る、出発被覆の変動幅よりも僅かな幅の公差範囲内にあるようにする:
を有していることを特徴とする、一連の円筒状の連続気泡性の物体を被覆するための方法。 - 実際量を、ステップa)での被覆前のかつ被覆後の物体の秤量によって検出する、請求項1記載の方法。
