Claim Text:
1. A method to install floor panels with a mechanical angling locking system at long edges and a mechanical locking system at short edges, the mechanical locking system at short edges comprising a tongue and a tongue groove each provided with protrusions and cavities, the method comprising the steps of: bringing a new panel and a second panel into a position where upper parts of the short edges of the new panel and the second panel are in contact, in which position the new panel and the second panel are in the same plane and in a second row with the long edges offset and with the short edges unlocked vertically and, optionally, locked horizontally; displacing one of the new panel or the second panel along the short edges until the long edges of the new panel and the second panel are aligned and some of the protrusions at one of the short edges vertically overlaps some of the protrusions at the other of the short edges to lock the short edges vertically and horizontally; bringing the aligned long edges of both the second panel and the new panel from being out of contact with a long edge of a first panel in a first row to being in contact with the long edge of the first panel in the first row; and angling down the second panel and the new panel along the aligned long edges to lock the long edges of the first panel, the second panel, and the new panel vertically and horizontally.
