  • Publication number: 20200308846
    Abstract: There is disclosed a mineral-based floor panel including a mineral-based core, wherein the panel includes at least one groove. The at least one groove may be provided in a rear side of the panel. There is also disclosed other such mineral-based panels, such as a building panel, a wall panel, a ceiling panel or a furniture panel. There is also disclosed a method for forming such grooves in a mineral-based panel. Furthermore, there is disclosed a mineral-based panel including a mineral-based core and polymer-based lower layer(s) attached to the core. A locking system of the panel includes a strip extending horizontally beyond an upper portion of the panel, wherein at least a horizontal portion of the strip is entirely formed in the polymer-based lower layer(s).

  • Publication number: 20200282589
    Abstract: A method for forming grooves in a board element. An exemplary method includes arranging the board element in contact with a support member, and forming at least one groove in a rear side of the board element by removing material, such as chips, from the board element by rotating one or more cutting devices including a plurality of tooth elements configured to rotate around a rotational axis. A method further includes counteracting, such as preventing, a displacement of the board element away from the support member during forming of the at least one groove, wherein the counteracting, such as preventing, includes arranging at least a portion of the board element between an obstruction element and the support member.

  • Patent number: 6754237
    Abstract: Method and apparatus for setting up a connection between a first terminal and a second terminal over an Integrated Services Digital Network (ISDN) link having one or more bearer channels that allow a user-selected protocol are provided. The terminals support a plurality of possible software protocols for use on the bearer channels. In order to facilitate new types of ISDN protocols on an existing system, the method includes the step of separating the protocol software into a generic module containing generic ISDN encoding/decoding protocols and into protocol specific modules containing specific types of ISDN encoding/decoding protocols.
