Rotary Filter Apparatus For Roll-To-Roll Nanomaterial Dispersion Papermaking
20190247796 · 2019-08-15 ·

An apparatus for roll-to-roll nanomaterial dispersion papermaking includes a suction pressure for consolidating nanomaterials on a fluid permeable filter in one region of the filter and an opposite pressure region or regions for separating a mat of the consolidated nanomaterials and transferring the mat to a transfer roller. A transfer roller may have a suction pressure within the transfer roller to help transfer the mat from the filter to the transfer roller, for example. An inlet port distributes nanomaterials using row and zone inlets, for example.

Laminated paper machine clothing

The invention relates to a clothing (10) for a machine to manufacture or refine a fibrous web, in particular a paper, cardboard, or tissue web, comprising a substrate (40) and a grid structure (20) applied on the substrate (40), on which the fibrous web is transported when the clothing (10) is used as intended, wherein the grid structure (20) comprises a plurality of first elements (24), all of which aligned in a first direction, and a plurality of second elements (26), all of which aligned in a second direction, which is different from the first direction, wherein the first elements (24) penetrate the second elements (26), forming the grid structure (20), such that an underside of the first elements (24) facing the substrate (40) and an underside of the second elements (26) facing the substrate (40) are located in a common plane. In addition, the present invention relates to a method for producing such a clothing.

SHEET MANUFACTURING APPARATUS, SHEET MANUFACTURING SYSTEM, CONTROL METHOD OF A SHEET MANUFACTURING APPARATUS, AND SHEET MANUFACTURING METHOD

Provided is technology improving the efficiency (productivity) of a sheet manufacturing apparatus. A sheet manufacturing apparatus 100 manufactures sheets S by heating with heaters 81 and 82 a mixture (second web W2) of resin and fiber produced by defibrating feedstock MA. The heaters 81 and 82 each have a first roller 171, a second roller 172 that holds the second web W2 with the first roller 171, and a moving mechanism 190. The moving mechanism 190 can switch the first roller 171 and second roller 172 to a position holding the second web W2, and a first roller 171 and second roller 172 are separated and do not hold the second web W2. The heaters 81 and 82 are configured as units that can removably installed to the sheet manufacturing apparatus 100.

METHODS OF MAKING PAPER PRODUCTS USING A PATTERNED CYLINDER
20190048525 · 2019-02-14 ·

A method of making a fibrous sheet including bringing a permeable patterned surface of a patterned cylinder into contact with a nascent web and conveying the nascent web between a transfer surface and the permeable patterned surface over an arc length of the permeable patterned surface. The arc length forms at least a portion of a molding zone. The method also includes applying a vacuum over at least a portion of the arc length. The method further includes transferring the nascent web from the transfer surface to the permeable patterned surface of the patterned cylinder in the molding zone. The vacuum is applied during the transferring of the nascent web from the transfer surface to the permeable patterned surface of the patterned cylinder.
