Abstract: A method for producing an air-laid product or a non-woven product from a starting material includes: comminuting starting material into a comminuted material in at least one comminution line by at least one comminuting device; feeding the comminuted material into at least one material buffer; removing the comminuted material from the at least one material buffer; metering the comminuted material by at least one metering device; supplying the comminuted material to at least one processing line with at least one defibration system in which the comminuted material is defiberized into a defiberized material; and feeding the defiberized material into a production machine and processing the defiberized material into an air-laid product or a non-woven fabric. The at least one metering device is controlled in such a way that a continuous mass flow of defiberized material is supplied to the production machine.

Abstract: A method for producing a web of fibrous material, the method including the steps of: forming the web by a dry-laying process; pressing and consolidating the web in a press nip while the web lies between a first support element and a second support element, a contact surface of the first support element and a contact surface of the second support element respectively facing the web; forming at least one low-pressure zone and at least one high-pressure zone in the web by way of the contact surface of the first support element; and exerting upon the web in the at least one high-pressure zone a pressure of more than 10 MPa.

Abstract: A machine for the production of a fibrous web, with a forming region, including a forming roll and a permeable inner belt which at least partially wraps around the forming roll together with an outer belt for formation of the fibrous web. A press device is immediately downstream from the forming region for additional dewatering of the fibrous web in a press nip and with a downstream drying cylinder. The fibrous web is carried supported on the inner belt from the forming region until the transfer to the heated surface of drying cylinder takes place. The inner belt is textured in order to provide texture to fibrous web and the transfer roll is a shoe roll in order to provide an extended transfer nip.

Abstract: Robotic work tool (100) configured for improved turning in a slope (S), said robotic work tool comprising a slope detector (190), at least one magnetic field sensor (170), a controller (110), and at least two driving wheels (130?), the robotic work tool (100) being configured to detect a boundary wire (250) and in response thereto determine if the robotic work tool (100) is in a slope (S), and if so, perform a turn by rotating each wheel (130?) at a different speed thereby reducing a risk of the robotic work tool (100) getting stuck.

Abstract: The present invention relates to a method (300) and a system (100) for navigating a robotic garden tool (202) based on one or more operating parameters for subareas (210-218) within the working area (204) and a current location of the robotic garden tool (202). The working area (204) is provided with a signal source (104) corresponding to which a sensor unit (106) is provided in the robotic garden tool (202) for detecting the one or more signals (102) from the signal source (104). The robotic garden tool (202) may include a low-accuracy positioning device (110) for providing co-ordinates of various subareas (210-218) and at any given instant, an approximate location of the robotic garden tool (202). The robotic garden tool (202) further includes a processor means (114) for comparing the coordinates of the subareas (210-218) and the approximate position of the robotic garden tool (202) to determine a current location of the robotic garden tool (202) in the working area (204).

Abstract: The invention relates to an arrangement for fractionating a suspension of fibrous material suitable for creating a web of paper, board, tissue or some other fibrous material into a short fiber fraction with a high proportion of short and/or stiff fibers and/or vessel cells and a long fiber fraction with a high proportion of long and/or flexible fibers, comprising a screen element with screen openings which is taken past at least one nozzle which directs a jet of the fibrous material suspension onto the screen element, wherein the long fiber fraction is collected on the side of the screen element that is facing the nozzle and the short fiber fraction is collected on the opposite side of the screen element.
