A paper or board machine forming section comprising: - a first wire loop passing over a first breast roll and forming a first single wire forming section in a first direction after the first breast roll, - a first head box for supplying a slice jet on the first wire loop at the beginning of the first single wire forming section to form a first web, - a first turning roll within the first wire loop for directing the first wire loop into a downwards inclined slope after the first single wire forming section, - a second wire loop passing over a second breast roll and forming a second single wire forming section in a second direction after the second breast roll, said second direction being opposite to the first direction, - a second head box for supplying a slice jet on the second wire loop at the beginning of the second single wire forming section to form a second web, - a second turning roll within the second wire loop for directing the second wire loop into a downwards inclined slope after the second single wire forming section, - a joining roll within the second wire loop after the second turning roll forming a joining point to the first web and to the second web between the first wire loop and the second wire loop, said joining point being below the horizontal level of the first single wire forming section, - the first single wire forming section and the second single wire forming section being essentially on the same horizontal level, and further - a pick-up unit within a pick-up fabric loop forming a pick-up point between the first wire loop and the pick-up fabric loop, wherein the first wire loop and the second wire loop are joined together in the joining point for combining the first web and the second web to be a combined web such that the first wire loop and the second wire loop are wrapped around the joining roll by a wrap angle α, characterized in that after the joining roll the first wire loop is separated from the second wire loop for transferring the combined web to the pick-up point such that the first wire loop travels in a horizontal or upward inclined direction between the joining point and the pick-up point. - a first wire loop passing over a first breast roll and forming a first single wire forming section in a first direction after the first breast roll, - a first head box for supplying a slice jet on the first wire loop at the beginning of the first single wire forming section to form a first web, - a first turning roll within the first wire loop for directing the first wire loop into a downwards inclined slope after the first single wire forming section, - a second wire loop passing over a second breast roll and forming a second single wire forming section in a second direction after the second breast roll, said second direction being opposite to the first direction, - a second head box for supplying a slice jet on the second wire loop at the beginning of the second single wire forming section to form a second web, - a second turning roll within the second wire loop for directing the second wire loop into a downwards inclined slope after the second single wire forming section, - a joining roll within the second wire loop after the second turning roll forming a joining point to the first web and to the second web between the first wire loop and the second wire loop, said joining point being below the horizontal level of the first single wire forming section, - the first single wire forming section and the second single wire forming section being essentially on the same horizontal level, and further - a pick-up unit within a pick-up fabric loop forming a pick-up point between the first wire loop and the pick-up fabric loop,
