Definitions

the invention relates to a press belt, in particular a press jacket, to form at least one between the orbiting Band and a respective counter surface lying press nip for the treatment of a fibrous web, in particular one Paper and / or cardboard web, with one made of elastomeric material existing matrix and at least two reinforcing the matrix Layers of reinforcement threads.
Such a press belt can, for example, in a Shoe press are used and especially for education at least one press nip extended in the direction of web travel serve, for example, by a press shoe to the Counter surface is pressed, the corresponding to this counter surface is adjusted.
the respective shoe press unit for example formed as a shoe press roll, this serves Press belt as a press jacket.
the aim of the invention is to provide a press belt of the type mentioned kind of creating that, especially in terms of reinforcement and further optimized their connection to the matrix material is and accordingly has an improved strength.
the object is achieved according to the invention in that the Reinforcement of a layer extending transversely to the tape running direction Reinforcing threads and a layer of itself in the tape running direction extending reinforcing threads that the respective thickness of the reinforcing threads of both layers at least is about 0.5 mm that the distance between the in Reinforcement threads extending transversely at most about 3 mm is that the distance between themselves in the tape running direction extending reinforcing threads at most about 2.5 mm and that the reinforcing threads of one layer of those of the other layer a distance in the direction of the strip thickness from each other, ranging from about 0 to is about 4 mm.
Press belt is the ratio between the volume of itself reinforcing threads extending in the tape running direction to the Volume of the reinforcing threads extending in the transverse direction greater than or equal to 1.
the ratio between the volume of the thread material of the Reinforcement and the matrix material is advantageous greater than or equal to 0.2.
the reinforcing threads can be at least partially structured or have a fibrous surface.
the enlarged Surface leads to improved adhesion.
Press tape are the layers of reinforcement threads completely embedded in the matrix material.
Figure 1 shows a schematic plan view of a section a gain in the manner shown in Figure 2 into the matrix 10 made of elastomeric material
Press belt here a press jacket 12
a such a press jacket 12 can form at least one between the circulating belt and a respective counter surface lying press nip serve through the one to be treated Fibrous web such as in particular a paper and / or cardboard web to be led.
the respective thickness d of the reinforcing threads 14, 16 of both layers is at least about 0.5 mm.
the distance a1 between those extending in the transverse direction Reinforcing threads 14 is at most about 3 mm.
the radially outward facing Reinforcing threads 16 to the radially further inside Reinforcement threads 14 in the direction of the tape or jacket thickness i.e. in the present case a distance a3 from each other in the radial direction on that in a range from about 0 to about 4 mm lies (see in particular Figure 2).
the ratio between the volume of the circumferentially L extending reinforcing threads 16 to the volume of the reinforcing threads 14 extending in the transverse direction in the present case greater than or equal to 1.
the ratio between the volume of the thread material of the reinforcement and the matrix material is greater than or equal to 0.2.
Figure 3 shows a schematic sectional view of a section a further embodiment one with a reinforcement provided press jacket 12.
the reinforcing threads 14, 16 a fibrous surface 18, whereby a better connection to the matrix 10 is guaranteed.
the radial distance is between the reinforcing threads 14 and the reinforcing threads 16 less than in the previously described embodiment.
these embodiments have the same Basic structure.
the reinforcement threads 14, 16 layers formed completely in both cases Embedded matrix material.
