Abstract: The invention relates to an oven for drawing fibers at elevated temperature, which oven is on two sides opposite one another provided with guide rolls dictating a zigzag up-and-down drawing trajectory for the fiber in the oven. In the oven according to the invention the drawing trajectory is at least 20 meters long and the rolls are driven. The invention also relates to a process for drawing fibers using the oven according to the invention, in particular to a process for producing highly oriented polyethylene fibers.

Abstract: A photosensitive material is dried by radiating heat from a guide plate, having high emissivity, which is disposed along a conveying path and is heated by a ceramic heater. Further, the photosensitive material is dried by a warm air, which is heated by a heater, blown onto the photosensitive material from nozzles. In the drying, because the warm air is also heated by the heated guide plate, the warm air can be risen to a predetermined temperature efficiently. Accordingly, because transferring the radiating heat and the blowing the warm air are performed at a same position (a same member), the drying can be performed efficiently without enlarging the device.

Abstract: A method and apparatus achieve a more sustainable lift of a wet or heavy pulp web from a pulp machine to the topmost drying level of a pulp drying, allowing the speed of production to be increased and runnability problems to be minimized. The pulp web is lifted from the last press of the pulp machine to the topmost of the drying levels of the pulp dryer by supporting the web on a support wire. The pulp may be passed through the topmost drying level, and one or two other levels, also supported by a support wire, but in subsequent levels the pulp web is preferably supported only by an air cushion. In each level drying gas is blown toward the pulp web (preferably from both above and below the web) to effect drying, and the web passes around turning rolls between each drying level to enter the next, lower, drying level. The support wire may be of metal or plastic, and has a texture significantly coarser than the texture of wires commonly used in pulp machines.
