Abstract:
1. A device for applying a medium in the form of one of a liquid and a paste to a moving substrate, the substrate being one of a surface of a web of paper, a paper board, fibrous material and a transfer element, said device comprising: an application chamber; a first element associated with said application chamber on an output side of said application chamber in a direction of movement of the moving substrate; a second element associated with an input side of said application chamber; and at least one limiting element associated with a lateral end of said application chamber, said at least one limiting element adjusting a width of application of the medium on the moving substrate, said at least one limiting element having a flexible sealing plate that substantially seals a space between the moving substrate, said first element and said second element, said sealing plate including a fitted wearing body that is directed toward the moving substrate, said wearing body being proximate to said first element and said second element, said wearing body including a face directed toward the moving substrate having one of an inclinded roof-like form such that said face includes two planar sections inclined toward the moving substrate as said face extends in a direction transverse to said direction of movement of the moving substrate and slot-shaped incisions, said wearing body having specific characteristics that are superior to the rest of said sealing plate, said specific characteristics being a greater resistance to wear, a greater dimensional stability, a greater resistance to heat, and a lower coefficient of friction.
