Patent number: 10803725Abstract: A method and apparatus for determining presence of an object to be tidied in a washroom. A beam is supplied to a surface of the washroom at a first location. A reflected beam received from the surface of the washroom or received from an object in the path of the beam to the surface is detected. The presence of the object is determined from feedback from the beam based on a comparison of the feedback with a detection result when the beam reflects from the surface at the first location. An object to be tidied output signal is issued indicating that an object to be tidied is present based on the determination on the presence of an object.Type: GrantFiled: December 8, 2017Date of Patent: October 13, 2020Assignee: ESSITY HYGIENE AND HEALTH AKTIEBOLAGInventors: Anders Gustafsson, Eva-Li Saarväli, Urban Gabrielsson

Publication number: 20120255671Abstract: A method for producing a multi-ply web including at least three plies of flexible material, such as paper and nonwoven material, by means of gluing the plies. The method includes the steps of embossing first and second webs of flexible material separately between a respective embossing roll and a respective impression roll; applying glue to one side of each of the embossed first and second webs; feeding the first and second webs and a third web separately into a laminating nip. The third web is between the first and second webs, and the glue is applied to sides of the first and second webs facing the third web so that the first, second and third webs are combined in a single step.
