A sheet manufacturing apparatus that manufactures a sheet-shaped recycled paper using coarsely crushed pieces obtained by coarsely crushing a sheet containing fibers as a raw material, includes a container loading section that is configured to load a container in which the coarsely crushed pieces are housed and which has an information carrying section for carrying information related to characteristics of the housed coarsely crushed pieces, a reading section that reads the information carried by the information carrying section, a determination section that determines whether or not the coarsely crushed pieces in the container are suitable as the raw material for sheet manufacturing by the sheet manufacturing apparatus based on the information read by the reading section, and a switching section that switches between a first state in which the container is configured to be loaded into the container loading section and a second state in which the container is prevented from being loaded into the container loading section according to a determination result of the determination section.

A sheet manufacturing system includes a coarsely crushing apparatus that coarsely crushes a paper, a sheet manufacturing apparatus that generates a sheet-shaped recycled paper using coarsely crushed pieces of the paper as a raw material, and a server that is connected to the coarsely crushing apparatus and the sheet manufacturing apparatus via a network, in which the coarsely crushing apparatus has an integration section that integrates the coarsely crushed pieces, an integration amount detector that detects an integration amount of the coarsely crushed pieces in the integration section, and a transmission section that transmits information related to the integration amount, which is detected by the integration amount detector, to the server, and the sheet manufacturing apparatus has a reception section that acquires the information related to the integration amount from the server, a display information generation section that generates display information related to the integration amount based on the information acquired by the reception section, and a display section that displays the display information.

A method for creping paper includes applying an adhesive composition to an outer surface of a creping cylinder (Yankee cylinder) to form an adhesive coating, contacting paper with the adhesive coating, removing the paper and adhesive coating from the creping cylinder, and determining a quality of the adhesive coating. Determining the quality of the adhesive coating may include measuring a degree of cross-linking of the adhesive polymer, a concentration of the adhesive polymer in the adhesive coating, a water content of the adhesive coating, an ash content of the adhesive coating, or combinations thereof. Determining the quality of the adhesive coating may also include determining a thickness of the adhesive coating by measuring light absorbed by the coating and calculating the thickness using Beer's Law. Systems and apparatuses for determining the quality of the adhesive coating and for creping paper are also disclosed.

A monitoring system comprising: (a) one or more sensors that monitor activity, amplitude, size, scale, duration of activity or a combination thereof of stock on a paper machine and (b) a control system in communication with the one or more sensors and one or more foil sections within the paper machine; wherein the control system measures the activity, amplitude, size, scale, duration of activity or a combination thereof of the stock and correlates the activity, amplitude, size, scale, duration of activity or a combination thereof to formation of fibers within the stock so that an angle, height, or both of the one or more foil sections are adjusted to change the activity, amplitude, size, scale, duration of activity or a combination thereof in the stock.

A method for an assembly of a device includes providing a nonwoven production device having a supporting structure in a first transport container, the nonwoven production device being pre-assembled, providing an auxiliary unit in a second transport container, removing the nonwoven production device having the supporting structure from the first transport container, removing the auxiliary unit from the second transport container, releasing the nonwoven production device from at least one part of the supporting structure and positioning the nonwoven production device at a top side of the supporting structure, and establishing a fluidic connection between the nonwoven production device and the auxiliary unit.

Systems for providing efficient manufacturing of paper, sheet, and/or box products of varying size and structure, often with pre-applied print (“pre-print”), are provided herein. Efficient customer ordering/tracking, job aggregation, print imposition, corrugator planning, and tracking and adjustments throughout the manufacturing process are contemplated. A reel editor is configured to edit the roll based on waste and/or errors that occurred during various manufacturing processes (e.g., during printing). A control plan defining what is on each roll of printed web product may be updated after editing. Depending on the configuration, the reel editor may be integrated with various manufacturing components. The reel editor may be configured to determine if there is enough waste on the roll to even making editing worthwhile, such as based on desired quality of the images, customer requirements, different price points, among other possible factors.

A sheet manufacturing apparatus includes a pressing unit, a separate sheet shaping unit, a transportation unit, and a cutting-off unit. The pressing unit includes a pressing roller that presses a material containing fibers and a binder, which has a function of bonding the fibers together, to form the material into a shape of a continuous sheet. The separate sheet shaping unit cuts the continuous sheet into a shape of a separate sheet. The transportation unit is provided between the pressing roller and the separate sheet shaping unit and transports the continuous sheet formed by the pressing unit to the separate sheet shaping unit. The cutting-off unit is provided between the pressing roller and the transportation unit. When transportation abnormality occurs on the continuous sheet that is being transported, the cutting-off unit cuts off, from the continuous sheet, a part of the continuous sheet where the transportation abnormality occurs.

A system comprising: (a) a steam box; and (b) a monitoring system that monitors cleanliness of the steam box and is configured to connect to a paper machine.

According to an example aspect of the present invention, there is provided a method, comprising: controlling suction with predetermined force in a known measurement area to a moving cardboard or paper web in a manufacturing process, detecting on-line measurement information on deviation of the moving cardboard or paper web in the manufacturing process caused by the suction with predetermined force in the known measurement area, and determining elastic modulus of the moving cardboard or paper web in the manufacturing process on the basis of the measured deviation.
