Abstract
A process is proposed for laying and mechanically jointing floorboards provided with tongue and groove engagements on all sides for horizontal attachment. The process involves a) jointing of a number of boards and making them engage on their transverse sides n order to lay a first row on the floor of a room, b) jointing of a first board for a second row and making it engage with one or two boards in the first row using the tongue and groove joint on the longitudinal side for the purpose of starting a second row, c) pushing the tongue (or groove) of a second board into the groove (or tongue) on the transverse side of the first board in the second row, with movement from the longitudinal side towards the boards in the first row, and d) making the second board engage with one or two boards in the first row.
