摘要： Process and device for the mixing of suspensions with possibly different natures and/or compositions in the stable section of a paper machine. In the process, a suspension, particularly of the backwater of the paper machine, is piped in a mixing tube with the main flow direction in the longitudinal direction of the tube, and additional suspensions, with possibly different solid content, are injected. In the device, a mixing device and piping carry the suspension in the stable section of a paper or cardboard machine and blend suspensions with a higher solid content into a first suspension with little or no solid content. The mixing device and piping include a tube, at least one inlet for the first suspension, a plurality of feeds for the higher solid content suspensions to be admixed, and one outlet for the blended suspension, with a new solid content, arranged downstream from a bend in the tube. The mixing tube extends over a plane including sections of the tube upstream and downstream of the bend, and the impeller axis of a downstream pump is perpendicular to this plane.

摘要： Free flowing particles useful in absorbent articles are disclosed, including fibrous nits and methods of preparing fibrous nits. In one embodiment, fibrous nits are prepared from disperging cellulosic fibers in the presence of a nit conditioner which modifies nit particle size and properties for improved performance of the particles. In other embodiments, nits are prepared in multiple disperging steps or by disperging fibers under two or more conditions.

摘要： A strainer with a screen at its outer periphery is rotatably supported on a casing. A hollow pipe with paddles on an outer periphery of the pipe is fitted in the strainer. The hollow pipe is rotated at a rotating velocity different from that of the strainer. Slurry introduced into the hollow pipe is discharged through slurry outlets on the hollow pipe into inside of the strainer. Then, the slurry is hydrated by the screen under centrifugal action and is moved by the paddles toward a slurry outlet.
