A sheet producing method includes a web forming step of forming a web by accumulating fiber in a dry system, a water providing step of providing the web with water, and a compression-heating step of compressing and simultaneously externally heating the web provided with water, wherein a water content of the web provided with water in the water providing step is 12% by mass or more, and a compression degree of the web between before and after the compression-heating step is 1/7 or less.

The invention relates to a method and system for improving the application of a coating on a Yankee cylinder (CR) in tissue paper machines. The invention implements a moisture-controlled environment (12) in an area of the exposed Yankee cylinder between the take-off position (TO) and ahead of the transfer position (TP) of the web, i.e. before and/or after the application of a coating with Performance Enhancing Material (PEM), wherein the cooling effect on the Yankee surface is increased by increased evaporation rate of water in the coating or water additionally applied onto the coating.

A sheet manufacturing method includes forming a web by accumulating a mixture containing a fiber and a water-soluble polysaccharide in a dry manner, a moisture imparting step of imparting the web with moisture, and a pressurizing and heating step of pressurizing and heating the web to which the moisture is imparted, in which the pressurizing and heating step performs pressurizing and heating at the same time, a pressure higher than a pressure applied to the web in the pressurizing and heating step is not applied to the web before the pressurizing and heating step, and heating to a temperature higher than a temperature for heating the web in the pressurizing and heating step is not performed before the pressurizing and heating step.

A printing cylinder assembly for detecting existing and/or developing errors during printing comprising at least one printing cylinder which is suitable for printing on a material, and has at least one cylindrical body, at least one shaft forming a rotational axis for the body, and characterized by the printing cylinder which has at least one cavity extending from the surface of the body towards its interior volume, at least one sensor which is suitable for being placed in the said cavity, at least one communication interface which is suitable for communicating with an external device, at least one control unit which is adapted to receive data from the sensor, and transfer these data to an external device via the communication interface directly and/or by processing them, and at least one power supply which is for supplying the power needed by the sensor, the communication interface and/or the control unit.

A system for optimizing machine performance includes an optimization system and a data processing system. The data processing system records readings from data sources monitoring the performance of a machine and related aspects. The readings are processed at the optimization system and a machine learning model is trained to differentiate between data corresponding to an interval of optimal runtime performance and data corresponding to an interval of pre-error performance. The trained model is used to identify a subset of the various data sources that are most-predictive for a particular performance state of the machine, such as a pre-error performance state or an optimal runtime performance state. The subset of the various data sources are provided to a multivariate model for generating set-point recommendations for each of the most-predictive data sources. Visualizations are generated for providing real-time monitoring of deviations of the most-predictive data sources from the set-points associated therewith.
