  • Patent number: 10803725
    Abstract: 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.

  • Publication number: 20120255671
    Abstract: 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. The laminating nip is formed between the first embossing roll and a laminating roll.

  • Publication number: 20070178288
    Abstract: Method for producing a multi-ply web of flexible tissue material, such as tissue paper and nonwoven material, by gluing the plies. Glue is transferred in subsequent steps to a first web shaped flexible material via at least two patterned glue transfer rolls, in a pattern corresponding to the pattern of the glue transfer rolls. A second web shaped material is brought in contact with the glue bearing side of the first web shaped material in at least one press nip between at least one patterned lamination roll and an impression roll. The at least one lamination roll has a three-dimensional pattern having a shape and configuration so as to apply pressure to the combined first and second web shaped materials substantially only just opposite at least some of the glue bearing areas of the first web shaped material, and is driven in registry with the first and/or second glue transfer roll. A multi-ply product produced according to the method is also disclosed.
