Abstract
Process for manufacturing a press jacket of flexible material for a press device and a press jacket that is adapted to drain a material web in a press opening in a paper making machine. The process includes arranging at least one reinforcing fiber in a jacket material that forms the press jacket so that the reinforcing fibers are 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, and orienting the arrangment 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.

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;
- and
- orienting 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;
- and
- positioning 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.
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;
- orienting 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;
- and
- positioning 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 that is in a direction opposite the angle of inclination of the at least one reinforcing fiber to the machine direction.
A press jacket of flexible material for a press device adapted to drain a material web in a press opening, comprising:
- grooves running substantially in a peripheral direction in at least one surface of the press jacket;
- at least one reinforcing fiber embedded in the flexible material that substantially extends in a peripheral direction of the press jacket;
- and
- the grooves and the at least one reinforcing fiber being oriented relative to each other so that the grooves and the at least one reinforcing fiber do not run radially superposed over each other in a same direction, wherein the press jacket is adapted to rotate in a rotation direction;
- the grooves being formed at a groove angle to the rotation direction;
- the at least one reinforcing fiber being arranged at a fiber angle to the rotation direction;
- and
- the groove angle and fiber angle being different angles.
The press jacket in accordance with claim 25, wherein the axial groove distance and the axial fiber distance do not exhibit a common integral multiple.
