  • Publication number: 20230159718
    Abstract: The present disclosure relates to a silicone rubber foam layer obtainable by a process that includes providing a substrate; providing a first solid film and applying it onto the substrate; providing a coating tool provided with an upstream side and a downstream side, wherein the coating tool is offset from the substrate to form a gap normal to the surface of the substrate; moving the first solid film relative to the coating tool in a downstream direction; providing a curable and foamable precursor of the silicone rubber foam to the upstream side of the coating tool thereby coating the precursor of the silicone rubber foam through the gap as a layer onto the substrate provided with the first solid film; providing a second solid film and applying it along the upstream side of the coating tool, such that the first solid film and the second solid film are applied simultaneously with the formation of the adjacent layer of the precursor of the silicone rubber foam; foaming or allowing the precursor of the silicone

  • Publication number: 20150273926
    Abstract: The invention pertains to a device for forming the spine region and/or the adjacent joint areas of a book case prior to casing-in the book block by means of a forming component that lifts the spine region out of the extended starting position relative to rails that hold down the case boards or the joint areas, wherein the forming geometry of the forming component can be varied by means of motor-driven adjustments, and wherein a separate adjusting drive is assigned to each of the elements that can be adjusted relative to the base element and form the book case.
