Patent ID: 7779601

Claim:
A method for producing two different types of floorboards for making a floor with mechanically lockable floorboards, each of said two different types of floorboards along their four edge portions having pairs of opposing connectors for locking of adjoining first type and second type floorboards in both a vertical and a horizontal direction, a connector of the first type floorboard and second type floorboard designed to allow locking-together of the first type floorboard and second type floorboard in a first direction in a plane of the floorboards by at least snapping-in and locking-together in a second direction in the plane of the floorboards by inward angling and/or snapping-in, and the first type floorboard differing from the second type floorboard because the connector of the first type floorboard along one pair of opposite edge portions is arranged in a mirror-inverted manner relative to a corresponding connector along the same pair of opposite edge portions of the second type floorboard, the method comprising: linearly displacing a first floorboard blank and a first set of tools for machining a first pair of opposite edge portions of the first floorboard blank in a first direction relative to each other to produce a first pair of connectors; and linearly displacing the first floorboard blank with the first pair of connectors and a second set of tools for machining a second pair of opposite edge portions of the first floorboard blank with the first pair of connectors in a second direction relative to each other to produce a second pair of connectors, linearly displacing a second floorboard blank and the first set of tools for machining a first pair of opposite edge portions of the second floorboard blank in a first direction relative to each other to produce a first pair of connectors; and linearly displacing the second floorboard blank with the first pair of connectors and the second set of tools for machining a second pair of opposite edge portions of the second floorboard blank with the first pair of connectors in a second direction relative to each other to produce a second pair of connectors, wherein, the first floorboard blank with the first pair of connectors is directly transferred from the first set of tools to the second set of tools to produce the first type floorboard, and wherein the second floorboard blank with the first pair of connectors is rotated a half a turn in its plane and then transferred to the second set of tools to produce the second type floorboard having the second pair of connectors in the mirror-inverted position relative to the first type floorboard.
