摘要： The first invention aims to provide a method for preparing stiffer bulky pulp at a freeness level comparable to that obtained by mechanical treatments to improve the bulkiness of product paper by searching for a method capable of adjusting freeness while suppressing damage to pulp fibers and internal fibrillation in a process for producing pulp. The second invention aims to strip contaminants deposited on pulp fibers and/or inorganic particles to reduce adhesion of the contaminants and decrease microorganisms in a treatment of process water containing long pulp fiber fractions used in a process for producing pulp and paper, thereby clarifying process water and thus preparing high-quality pulp and paper.According to the first invention, cavitation is generated in a pulp suspension preferably by a liquid jet and the resulting fine bubbles are introduced into the pulp suspension to adjust the pulp suspension to a desired freeness by means of the impact force induced by collapse of the fine bubbles in a process for producing pulp. According to the second invention, process water containing 50% by weight or less, based on total solids, of long pulp fiber fractions used in a process for producing pulp and/or paper is treated by cavitation generated by a liquid jet and then returned to the process for producing pulp and/or paper and reused.

摘要： An apparatus for applying coating material in the form of stripes onto a film traveling in a predetermined direction is provided with a coating material nozzle which effuses coating material while supporting the film. The contact support surface of the nozzle in contact with the film is a flat surface, along which the film travels. The coating material nozzle has thereon applicator grooves for uniformly forming the cross-sectional shape of coating material applied in the form of stripes onto the film. Effusion ports or discharge ports for coating material are provided in the bottom surface of the applicator grooves. Coating material is fed to the coating material nozzle through a gear pump, which is adapted to control the coating material supply so that the coating material within the applicator grooves has a pressure lower than atmospheric pressure. In addition, there may be provided a plate member for blowing air uniformly and opposed to the contact support surface of the coating material nozzle contacted by the film. The air from this plate is blown against the traveling film on its rear side.

摘要： A papermaking raw material processor capable of reforming pulp in papermaking a process using cavitation includes a first pump 5 jets jet liquid and second pump 6 jets suspension containing; e.g., pulp fibers into a processing unit inside which cavitation is generated by generation of a jet stream. Inside processing unit 2, a jet stream generates cavitation to carry out a reforming processing in which ink, or the like, is removed from the fibers by a blast resulting from collapse of cavitation bubbles generated there. The liquid after reforming processing is returned to second tank 4, except for a part of it fed to downstream steps, while the suspension is processed, as circulated between processing unit 2 and second tank 6.
