Abstract
The invention relates to a creping blade (1) with a blade-like main part (8) made of metal, in particular steel or stainless steel, said main part having a working edge (2) which can be placed against a drying cylinder (3) and which adjoins an end face (4) with a counter-edge (5). Grooves (6) are worked into the end face (4) and are arranged at a distance to one another, and a wear protection layer (7) is provided on the wall of the main part (9) between the working edge (2) and the main part (8), wherein the grooves (6) are worked at least into the wear protection layer (7).
Claims7
A creping blade comprising:
- a blade-shaped steel body that has a cutting edge juxtaposable with a drying cylinder and that merges with an end face forming a counter-edge, wherein grooves are formed in the end face and are spaced from one another;
- and
- an antiwear layer between the cutting edge and a side face of the body turned toward the drying cylinder, wherein the antiwear layer forms the cutting edge, and wherein the grooves are formed both in the body and in the antiwear layer.
A creping blade for use with a drying cylinder, the blade comprising:
- a steel body having a side face turned radially toward the cylinder and an end face;
- a layer of wear-resistant material on the side extending to and defining a cutting edge, the layer having an end face merging with the end face of the steel body and defining a cutting edge closely juxtaposable with the cylinder, the end face of the steel body having a counter edge more remote from the cylinder than the cutting edge;
- and
- an array of grooves formed in the end faces of the layer and of the steel body, extending transversely from the cutting edge on the edge face, and spaced from one another parallel to the cutting edge.
