Device and methods for producing edge protection coatings, the device having a flexible base plate, a channel, and a sealing lip

A device for applying at least one coating material to a substrate surface, the device comprising:

• a flexible base plate comprising,
• a top side,
• a bottom side which is arranged opposite to the top side,
• a front side,
• a back side which is arranged opposite to the front side,
• a left side,
• a right side which is arranged opposite to the left side, and
• a toothed surface comprising a plurality of teeth, wherein,
• the toothed surface is mounted on at least two of the sides of the flexible base plate as toothed sides;
• each of the plurality of teeth have a length, a width, and a height;
• the plurality teeth are arranged to have a spacing between each other in a width direction of each of the plurality of teeth along the front side of the flexible base plate and the top side of the flexible base plate,
• a length section of the length of each of the plurality of teeth project beyond the front side of the flexible base plate, and
• a height section of the height of the plurality of the teeth extend above the top side of the flexible base plate,
• a flexible channel which is arranged parallel to a first toothed side, the flexible channel comprising a first filler neck arranged on the left side, a second filler neck arranged on the right side, and a plurality of outlets on a side facing the first toothed side;
• the first filler neck and the second filler neck are configured to connect to a supply of the at least one coating material;
• and
• the at least one coating material is applied to the substrate surface via the plurality of outlets;
• and
• at least one sealing lip which is arranged on a side of the flexible channel which faces away from the first toothed side,
• wherein at least one of the toothed sides is arranged at least,
• on the top side of the flexible base plate so that the plurality of teeth of the toothed surface extend in a direction parallel to a direction of each of the left side and the right side and extend perpendicular to a direction of a plane of the top side and to a direction of a plane of the bottom side, and
• on the front side of the flexible base plate so that the plurality of teeth of the toothed surface extend parallel to a direction of a plane of each of the left side and the right side and extend perpendicular to a direction of a plane of the front side, and wherein the flexible base plate is configured to attain a bending radius.
