  • MECHANICAL LOCKING SYSTEM FOR FLOOR PANELS
    Publication number: 20200087927
    Abstract: Floor panels are shown, which are provided with a vertical folding locking system on short edges that only locks vertically and a mechanical locking system on long edges that prevents displacement along the long edges. A locking system for primarily rectangular floor panels with long and short edges installed in parallel rows, which allows that the short edges may be locked to each other with a vertical movement without a horizontal connection and that such horizontal connection is accomplished by the locking system on the long edges including a first and second horizontal locking perpendicular to the edges and along the edges.

  • DIGITAL EMBOSSING
    Publication number: 20200079114
    Abstract: A method of forming a digital embossing on a surface by bonding hard press particles to a carrier. A liquid binder pattern is applied on the carrier by a digital drop application head. Hard press particles are applied on the carrier and the binder pattern such that some hard press particles are bonded to the carrier by the liquid pattern and non-bonded press particles are removed. The carrier with the bonded hard press particles is pressed to the surface and an embossing is formed when the carrier with the hard press particles is removed.
