Abstract
The invention relates to a press belt (1) made from an elastomer material and forming a closed loop, the belt having an inner surface (2) and an outer surface (3) and three layers of reinforcement yarns (7′, 5′, 6′) arranged inside the elastomer material. In the invention, an outermost yarn layer (7) is formed by longitudinal and transversely adjacent reinforcement yarns (7′) of the press belt (1), which absorb energy and are restored from deformation with delay in connection with deformation.
Claims9
A press belt made from an elastomer material and forming a closed loop in a longitudinal direction, a transverse direction being perpendicular to the longitudinal direction, the belt having
- an inner surface and an outer surface and three layers of reinforcement yarns arranged inside the elastomer material,
- an innermost yarn layer closest to the inner surface extending in the longitudinal direction and having adjacent reinforcement yarns spaced in the transverse direction,
- a middle yarn layer extending in the transverse direction and having adjacent reinforcement yarns spaced in the longitudinal direction, and
- an outermost yarn layer closest to the outer surface of the press belt extending in the longitudinal direction and having adjacent reinforcement yarns spaced in the transverse direction, which absorb energy and are restored from deformation with delay in connection with deformation,
- wherein the material and/or structure of the reinforcement yarns of the outermost yarn layer are more flexible than the reinforcement yarns of the innermost yarn layer and middle yarn layer in such a manner that in connection with deformation of the press belt they absorb more energy and are restored from the deformation more slowly than the yarns of the other yarn layers.
