Abstract

Ein Preßband wie insbesondere ein Preßmantel zur Bildung wenigstens eines zwischen dem umlaufenden Band und einer jeweiligen Gegenfläche liegenden Preßspaltes zur Behandlung einer Faserstoffbahn wie insbesondere einer Papier- und /oder Kartonbahn umfaßt eine aus elastomeren Material bestehende Matrix und wenigstens zwei die Matrix verstärkende Lagen aus Verstärkungsfäden 14, 16. Die Verstärkung umfaßt eine Lage aus sich quer zur Bandlaufrichtung L erstreckenden Verstärkungsfäden 14 und eine Lage aus sich in Bandlaufrichtung L erstreckenden Verstärkungsfäden 16. Die jeweilige Dicke d der Verstärkungsfäden 14, 16 beider Lagen beträgt zumindest etwa 0,5 mm. Der Abstand a1 zwischen den sich in Querrichtung erstreckenden Verstärkungsfäden 14 besitzt einen Wert von höchstens etwa 3 mm. Der Abstand a2 zwischen den sich in Bandlaufrichtung L erstreckenden Verstärkungsfäden 16 beträgt höchstens etwa 2,5 mm. Die Verstärkungsfäden der einen Lage weisen von denen der anderen Lage in Banddickenrichtung einen Abstand voneinander auf, der in einem Bereich von etwa 0 bis etwa 4 mm liegt.

Figure 00000001
A press belt such as, in particular, a press jacket for forming at least one press nip between the circulating belt and a respective counter surface for treating a fibrous web, in particular a paper and / or cardboard web, comprises a matrix consisting of elastomeric material and at least two layers of reinforcing threads 14 that reinforce the matrix , 16. The reinforcement comprises a layer of reinforcing threads 14 extending transversely to the tape running direction L and a layer of reinforcing threads 16 extending in the tape running direction L. The respective thickness d of the reinforcing threads 14, 16 of both layers is at least about 0.5 mm. The distance a1 between the reinforcing threads 14 extending in the transverse direction has a value of at most about 3 mm. The distance a2 between the reinforcing threads 16 extending in the tape running direction L is at most about 2.5 mm. The reinforcing threads of one layer are at a distance from one another in the strip thickness direction, which is in a range from about 0 to about 4 mm.
