Abstract:
A process for manufacturing a press jacket of flexible material for a press device, the press jacket adapted to drain a material web in a press opening in a paper making machine, the process comprising:arranging at least one reinforcing fiber in a jacket material that forms the press jacket, the reinforcing fibers arranged to run substantially in a peripheral direction of the press jacket;forming grooves to run substantially in the peripheral direction in at least one surface of the press jacket; andorienting the arrangement of the at least one reinforcing fiber and the formation of the grooves relative to each other so that the at least one reinforcing fiber and the grooves do not run radially superposed in a same direction, wherein the grooves are formed in the press jacket prior to the arrangement of the reinforcing fibers;positioning the grooves at an angle of inclination to a machine direction of the press jacket; andpositioning the at least one reinforcing fiber at an angle of inclination to the machine direction of the press jacket,wherein the grooves are positioned in the press jacket at an angle of inclination to the machine direction greater than the angle of inclination of the at least one reinforcement fiber to the machine direction.
