摘要:
A sheet manufacturing apparatus includes a rotatable drum unit that includes an opening unit having a plurality of openings on a surface thereof and a cylindrical unit having no opening; a material supply unit that is provided to supply a material containing fibers to the drum unit by airflow; and a forming unit that forms a sheet by using the material passing through the openings, in which at least one of the drum unit and the material supply unit has a dispersion unit in which airflow is dispersed further on a downstream side than on an upstream side in a supply direction of the airflow.

A diagonally joined cylindrical fabric in the form of a cylindrical endless fabric is obtained by shifting ends of facing wefts of a non-endless fabric leftward or rightward and joining together the ends of the wefts to thereby form a joining portion inclined relative to an axis of a cylinder. The cylindrical fabric comprises a weave pattern in which warp passes over continuous two or more wefts, then passes under a less number of wefts, the joining portion at ends of the fabric formed into an endless cylindrical shape is inclined relative to the axis at 25° to 5°. The surface of the cylindrical fabric is formed with crimps that are longer in a face length direction than in a circumferential direction.
摘要:
In the present invention, in a process in which a fiber suspension supplied in a flat layer manner is subjected to natural dehydration, pressure dehydration, or suction dehydration, while circulating a cylindrical suction cylinder, and thereby, dehydration slowly proceeds and a paper web is formed, and this paper web is moved to an endless felt by means of a suction couch roll to produce paper, a tapered suction roll sleeve 6, the outer peripheral surface of which is cylindrical and the inner peripheral surface of which has an inclination identical to that of the outer circumference of the tapered suction roll cell 5 is attached and detached, and thereby, it becomes easy to conduct the attachment and detachment of various types of wires wound on tapered suction roll sleeve 6.
